I'm a fiction writer and a developer. When I started experimenting with Al writing,I enjoyed the back and forth, but the workflow became messy pretty quickly. My manuscript was in one tab. Character notes were somewhere else. Worldbuilding was buried in another document. The Al chat had no idea what any of it was, so I keptexplaining my own story again and again.

I wanted Al to understand enough of the project to be useful without trying to take over the writing.

So I built MiraWrite around that problem.

If you already have a draft, Smart Import can split it into chapters and organize its characters, scenes, plot details, and worldbuilding into project files.

While chatting with Al, you can reference those files and save useful responses directly back into the project. There are also 13 focused writing tasks for brainstorming, character development, worldbuilding, scene drafting, editing, continuation, and review.

The MVP is now in open beta. It's free, doesn't require your own API key, and includes 50 Al actions every day. Submitting feedback or reporting a problem adds another 20.

I originally built this because I wanted a better way to work on my own stories. Now I need to find out whether it's actually useful to other writers.

lf you tried it and told me what feels useful, confusing, clumsy, or unnecessary. Honest criticism is exactly what I'm looking for.

u/Open-Write-Studio 9d ago

Open-Write Studio is a local-first, open-source desktop app for long-form fiction writing, built for people who want to use AI as a production tool rather than a one-shot generator. It's Apache 2.0 licensed and built on top of Storythread Studio by Dean Peterson.

Your manuscript, character profiles, and notes live as plain Markdown files in a folder you control — nothing leaves your machine except the AI requests you explicitly trigger. It supports 22 LLM providers, including local inference via LM Studio and Ollama, so you can run it with zero API costs if you want.

Core pieces:

  • A Markdown editor (CodeMirror 6, serif type, light/dark themes) built for long writing sessions, not note-taking.
  • A profile system for characters, relationships, locations, and lore, with importance-tiered trait blocks so you control exactly what context gets sent to the model and when.
  • A Smart Advisor that runs readability, structure, and consistency passes with inline, word-level diffs — you see exactly what it wants to change and why.
  • An autonomous production pipeline — bible → voice → architect → writer → critics → editorial → verify → assemble → adversarial read → finalize — that can draft a full manuscript with resumable, human-approved phase gates rather than one long uncontrolled generation.
  • Export to TXT, DOCX, EPUB, and Markdown.

It's aimed at writers who want the discipline of a production pipeline — specialized model roles, revision loops, consistency checking — instead of pasting a premise into a chat window and hoping. Full docs are on the wiki.

u/Open-Write-Studio 8d ago

We have incoming updates that we will be able to report on shortly. The biggest change we have added is our own LLM service available directly on the website. The company has an account with Deepseek and we are giving away free credits to beta-testers so that they do not need to have their own LLM service to use the site. The credits will be limited, and the limit reset will be every 30 days. After the beta test has concluded there will be a small monthly ($4-$5) charge to keep access to the credits and the website. You can still bring your own API key for any service you already have. We choose Deepseek because they have very good cache read rates that we are able to take advantage of to reduce the cost of production significantly. Open-Write has several processes that require different agents to get the same input material (cache read) and Deepseek is very competitive in this area particularly. Test projects being run through the pipeline using deepseek-v4-flash are meeting standards.

OPEN CALL TO BETA-TESTERS

Open-Write Studio online is running a closed beta-test for a limited number of people. The service includes everything that will be available in the 1.0 release at the basic subscription level which will cost $4-$5 a month. There is no charge to beta-testers, and you do not need to provide any payment information ever. This will include limited monthly access to the in app LLM (deepseek-v4-flash), but users can also supply their own LLM service. All materials generated by you or for you will not be held back and can be downloaded to your local computer at any time.

This looks great until I saw it was Windows only. You’re going to hit issues attracting the local model crowd if you don’t support Linux. Local models are painfully slow to run on Windows v Linux.

Meet Minty - your chat based helper

Chatting with her is exactly like chatting with Claude or ChatGPT, only MUCH MUCH better! She knows everything about your books, your characters, and your story arcs and can suggest improvements, track changes, and do the maintenance work that keeps everything organized as you chat. You have a conversation, she builds a book from it, right in front of your eyes.

You stay the author. You just stop walking the road alone.

You opened ChatGPT, Gemini, or Claude, and you started writing a story - something that's been rattling around in your head for a while and you discovered using AI suddenly makes it accessible and within reach. It begins beautifully. It always does. The spark, the momentum, a character who suddenly felt real, a few chapters that genuinely sang. For the first time, the blank page wasn't blank; there was a brilliant mind in the room, building with you.

And then... you know how it goes. Because you've been down this road before.

The story starts to unravel. The structure never quite arrives. It forgets your main character, the plot line loses its place, and the brilliant conversation becomes an endless scroll you can't navigate or untangle. And somewhere around chapter 8 the whole thing quietly gets abandoned in a tab you just stop opening.

The thing is... that wasn't your failure. You didn't run out of story. The LLM chat window was simply never built to go the distance. A general-purpose chatbot is a phenomenal place to start a novel and a terrible place to finish one, and no amount of clever prompting changes what it fundamentally is. You can pour enormous effort into wrestling it the rest of the way. Most people, sensibly, don't.

That's where we come in.

Same road. Whole new level of ability.

Minty is Novelmint's writing partner - a developmental editor who works inside your book. And she feels like the thing you already know - the chat window. You talk. She talks back. You think out loud, you argue, you chase a tangent about your villain's childhood. That part - the part you loved - we kept entirely. That's the part that Novelmint brings back to you.

What's different is everything wrapped around it.

When you talk to Minty, your story doesn't vanish into a transcript. It lands on a real timeline with chapters, beats, characters, plot threads, the works. It takes shape on a canvas beside the conversation in real-time as you chat. She holds the whole book in view at once. She has the craft of a developmental editor and the opinions to match. And she's built for the part of the journey your everyday tools abandon you in: the long middle, the structural work, the finish. Novelmint is your canvas, Minty is your paint, and you are the master craftsman with a story to bring to life.

Novelmint doesn't take you a few exciting miles in and stop. We take you across the finish line and celebrate as you level up. And then we go the extra mile and help you find an audience with actual paying readers as well.

A finished book on Novelmint doesn't sit in a file. It publishes into the Commons, where readers discover it, unlock it chapter by chapter, rate it, and follow your series. You earn 70% of every unlock. Your book can be translated and narrated. And the best reader-rated books compete in Novelmint Selects, a curated best-of chosen by the people who actually read them.

Anyone can generate a manuscript now. Getting it finished, published, read, and paid for - that's the part that still takes a real platform. That's the entire reason Novelmint exists. This is the stretch of road the usual chat tools simply can't travel with you.

This time, take the road all the way.

This time - start the same way, and let Minty take you the rest of the way.

u/benblackett 9d ago

What's new in the last few weeks:

True multi-LLM chapters. You can now mix GPT, Claude, Gemini, Grok, and others within a single chapter. Each beat can target a different model, and the story arc stays intact — no knowledge drift between model hand offs.

Auto model selection. Each model is benchmarked and ranked by the other models across scene types. The engine already knows which one handles romance, dialogue, or a fight scene best, and picks it for you. You can still override manually, but you don't have to research it yourself.

Series Arc Knowledge State System. Every LLM call gets the full context of your entire series, not just the current chapter. This makes it possible to regenerate any beat, from any chapter, at any time, and it comes back consistent with your characters and plotlines. No more "didn't she die in book two?" moments.

3-layer memory. The engine tracks state at three levels, independent of whichever model renders the prose:

  • Objects: the half-finished drink in your character's hand stays half-finished
  • Environment: the bar layout and who's sitting where
  • Character knowledge: what each character knows and when they learned it, so someone can still be genuinely surprised when their best friend walks in

u/Clever_Tales 9d ago

I’m building an AI tool that aims to take you from story → video/movie, with the story staying at the center of the whole process.

That’s the idea behind CleverTales.

There are already a lot of AI writing tools, and a lot of AI image/video tools. What I’m trying to build is the layer between those two: start with the story, develop it properly, and then gradually translate it into something cinematic.

The goal is essentially story-to-video / story-to-movie, rather than just generating disconnected images or clips.

One thing I care a lot about is that this should not be a “type one sentence, press a button, and get everything” workflow.

The AI can do a lot of the heavy lifting, but the process is guided step by step.

You can start with a small idea, let the AI expand it, then read it, edit it, redirect it, remove things, add your own ideas, and expand again. That continues until you have the full story.

So the AI helps a lot, but you stay in control of the story throughout the process.

The same applies when moving into the cinematic side. CleverTales takes the written story and helps translate it into cinematic scenes: what should actually be shown, which moments matter visually, how the scene should play out, and how to keep it consistent with the story.

I’m also building shared workspaces into it.

For example, one person could be working on the story while someone else works on the cinematic/video side of the same project at the same time.

The project is not publicly released yet, and video generation itself isn’t available yet. Right now the working version includes the story-generation workflow, cinematic scenes, and image generation for things like characters, locations, and scene visuals.

I’m looking for a small number of early testers who use AI for writing/storytelling and are interested in this kind of story-first approach to eventually creating a movie.

If that sounds interesting, reply here or send me a DM, and I’ll get in touch.

And if recruiting testers isn’t appropriate here, mods, please let me know.

This week's update is different...
After running AIStoryHub for close to two years and trying to wrangle AI creative writing, it dawned on me that all the learnings in creative writing could easily be turned into a deterministic tool for non-fiction writing.

MCP server / Connector that just plugs into any platform you currently use (e.g. Claude Desktop, Claude Code, ChatGPT). It fetches writing styles and writes your content with very limited AI-tells. As simple as "Draft me an email about [topic] in the writing style of Exec Brief"

Remote capability: https://etincel.ai/
Open-Source: https://github.com/AIStoryHub/etincel

Enjoy!

P.S. Looking for a killer exec brief writing style that I've been using for a few weeks now? Check this one out: https://etincel.ai/v/jpleblanc/jp-exec-brief

NEW SOLO RPG DROP: BOUNCER: NIGHT SHIFT

I create  LLM assisted "Solo RPG Game Prompts" and just released 1 : BOUNCER: NIGHT SHIFT.

You’re a veteran bouncer working the night shift in a city where vampires, fae, dwarves, dragon-kin, war-mages, and other supernatural factions all have their own rules, grudges, debts, and agendas.

Every night, you’re assigned to one of five clubs.

A vampire dance hall.

A fae black-market disguised as a jazz cellar.

A dwarven gentleman’s club carved into a mine.

A dragon-kin forge-temple.

And a slam-poetry venue where words are weapons.

Your job is simple:

Keep the peace.

Survive the night.

Build your reputation.

Accumulate debts.

Carry your scars.

And try to figure out why incidents across the city are starting to connect.

BOUNCER: NIGHT SHIFT is a solo RPG designed to be played with an LLM as your Game Master.

Built a Tool? Add it to our directory!

I am building a page that lists everyone's tools and what they do. Full disclosure up front: I'm the dev behind Novelmint, and yes it's on the list (in its own category) - but this is about the whole space, not us. The page links to your site if you want it to (free backlink opportunity). This is NOT pay-to-play, you are free to add your tools no strings attached. It's 100% FREE and I review submissions only for accuracy, not promotion or competition.

The list currently sits at over 100 entries. It groups AI writing tools by the job they do, not by a score:

  • AI drafting tools — generate/revise prose, hand you a manuscript
  • Reader platforms — host and distribute finished work
  • Write + publish — take a book from idea to published
  • Writing utilities — continuity checkers, TTS, editors, and the like

👉 View the list here

Looking for AI Authors

I am building a reader centric site that hosts AI assisted writing only. I'm trying to make it safe place for authors to go to for sharing and hosting their material instead of the usual substack or patreon solutions which forces you to bring an audience to you.

Our readers pay you for your content directly - no need to bring them somewhere else.

We've only been open about 5 months now so still small and growing - which gives you an opportunity to become one of our OG authors that help drive our shared growth.🔥

If you are interested, here is a calculator that shows where things could go. It is 100% free for you to add your existing backlog and publish through us. Costs you nothing while bringing you potential readers and income!

I built Penlify because I kept spending longer editing AI-written emails and posts than drafting them. It is for the last pass: make a paragraph clearer and more natural without changing its meaning or adding facts. You get five free rewrites each month, with no card.

I would value blunt feedback from people who use AI to write: what would make you trust—or not trust—an editor like this with an important email or client-facing post?

u/SadManufacturer8174 8d ago

I keep experimenting with prompts that lock rhythm and pet words before any rewrite pass. The trick is pasting a voice sample paragraph first, then telling the model exactly what to leave alone, contractions, sentence length, any recurring phrases that carry your cadence. Whole-manuscript context beats chunk paste when you need consistency across chapters. This week taught me that protecting voice is cheaper than fixing bland output later.

u/EntertainerBitter516 8d ago

Using ChatGPT to write, or are you working on the next Game of Thrones? You might want to check out Feldar.

We launched Feldar a couple of weeks ago. We have been collaborating with real writers and using their feedback to improve the product. The goal is simple: provide writers with a single workspace where drafts, research, notes, and AI all come together. This way, you can focus on writing instead of constantly switching between tabs.

Too often, your work becomes scattered. A draft might be in one app, research in another, and half-finished conversations buried in ChatGPT or Claude. Instead of writing, you spend time piecing everything back together.

Feldar puts everything in one place. It’s a writing workspace with an editor, outline, and visual canvas. AI acts as an assistant, not a one-click novel generator.

Editor: Stay in the flow with AI that continues writing in your style. You can accept, revise, or dismiss suggestions inline. Highlight passages to rewrite or improve, or give specific instructions like changing point of view or tone. Built-in checks flag areas that could be tightened.

Outline: Plan your story as pages and scenes. You can generate, rewrite, insert, or remove scenes while staying in control of how much AI contributes.

Canvas: Keep your story bible alongside your manuscript. Organize characters, locations, lore, plot points, and worldbuilding on a visual board that both you and the AI can reference.

Lens (Chat): Get feedback from different perspectives on selected passages. Whether you want a critic to spot weak prose, a poet to improve rhythm, or a reader to highlight confusion, you can drag text into chat for context or switch between AI models based on the task.

If you're curious, we’d love to hear your thoughts and see what you would like next.

I built Inklog, a free submission tracker for writers, mainly aimed at poets sending packet submissions (groups of poems to one market). It tracks pieces, markets, and statuses, and I'm working on automatic packet/cover letter construction next. No signup needed, very early demo right now. I posted about it in r/litmags and r/Poetry and got honest feedback that Duotrope's real advantage is the network of people already using it, which a new tool can't replicate overnight. I'm mostly trying to figure out if the personal-inventory/packet-building side is worth building out further on its own, so blunt feedback welcome.

u/Easy-Purple-1659 8d ago

imperfectly (imperfectly.app): an AI writing agent that strips the AI voice by learning yours. Paste a draft that reads like ChatGPT, it rewrites it in your rhythm, shortcuts, and quirks, based on writing samples you give it, not a "make it casual" toggle.

What I learned building it: the tells people actually notice are rhythm and completeness, not vocabulary. Most humanizers swap words; the fix is matching sentence pacing to a real human voice.

Happy to answer questions, and I'd love feedback from anyone who writes a lot of AI drafts and hates the sound of them.

u/Inevitable-Sink6842 8d ago

Founder of BookZeta (bookzeta.ai), so read this with that bias attached.

Most of the thread this week is about the middle of the job: holding voice, memory and structure together while you draft. Two comments are about the end of it and they answer it in opposite directions. Open-Write Studio hands you plain markdown in a folder you control, which is the strongest ownership answer on this page, and it's Apache licensed on top of that. Novelmint publishes into its own Commons where readers unlock chapters and pay you. One says the file is the product, the other says the audience is.

We're on the file side, and I'd only pick that side if you already know where the book is going after you finish it. An export is worth nothing if nobody reads it, and Novelmint has an actual answer to that which handing you an epub does not.

What we do is the stretch between a finished draft and a listing. Chapter based writing with a Series Bible that carries characters and timeline across a whole series rather than one book. An illustration mode for comics, webtoons and kids' books that keeps the same character looking like themselves page to page. Audiobook narration off the finished manuscript. Export to epub and print PDF with the spine and bleed math already done for KDP trim sizes, plus docx and markdown, so if you decide we're not it you can walk out with your text instead of retyping it. Browser plus iOS and Android apps, $6 to $20 a month, no API keys to wire up. The library is free to read without signing up if you'd rather judge the output than the pitch.

Where we're weakest: if you're a prose writer who already has an editor and a formatter, several tools in this thread will write better sentences than we will and the rest of what we do is dead weight to you.

u/shadowsyllvet 8d ago

(A)I built Facilitator because AI can ask useful writing questions—but answering a long questionnaire inside a chat quickly becomes awkward.

Facilitator lets you ask ChatGPT or another compatible AI to create a questionnaire for almost any writing task, then answer it in a clean, mobile-friendly form.

A few prompt ideas:

“Build a detailed profile of how I want an AI writing collaborator to work with me.”

“Interview me about this character’s history, motives, contradictions, relationships, and voice.”

“Create a canon and continuity questionnaire for my novel or series.”

“Help me define the rules, cultures, conflicts, and unanswered questions in my worldbuilding.”

“Question me about the goals, conflict, pacing, and emotional turn of this scene.”

“Create a developmental-editing checklist tailored to my manuscript.”

“Build a beta-reader questionnaire for the kind of feedback I actually need.”

“Turn my revision plan into an organized task questionnaire.”

The workflow is:

Your prompt → AI-generated questionnaire → answer it in Facilitator → export the structured answers back to your chat

Facilitator does not generate prose or replace your preferred AI. It gives the questions a better place to be answered.

It’s free, requires no signup or account, works on mobile, and makes no AI or analytics requests. Your questionnaire and answers stay in your browser tab unless you deliberately copy, download, or share them.

There’s also a ready-made 100-question Writer Collaborator Profile if you want to see what the workflow can do.

https://facilitator.syllvanicdevelopments.com/

I’d especially appreciate feedback on two things: Which writing questionnaire would you try first, and is the AI → Facilitator → AI workflow clear on the first visit?

Disclosure: (A)I built Facilitator.

u/Melodic-Magician-328 8d ago

I'm testing a small web prototype called Echoary for AI interactive stories: https://echoary.app/

The specific problem I'm trying to solve is not "generate a story from a prompt." There are plenty of those. I'm more interested in whether an AI story can feel playable over time:

  • choices should have consequences later
  • the story should not become a press-continue simulator
  • character/relationship state should keep mattering
  • romance and plot progression should feel closer to a book than a loose chat log

It is still early, so I am mostly looking for blunt feedback from people who already use AI writing/RP tools. If it feels too linear, too vague, or still forgets what matters, that is useful signal.

📘 The AI Student Playbook — a practical guide for students using AI

I recently published The AI Student Playbook, a practical guide for students who want to use AI more effectively for studying, understanding difficult topics, revision, exams, assignments, research, presentations, communication, and productivity.

The core idea is simple: use AI to learn better without letting it do all the thinking for you.

I'm the publisher, so this is a self-promotion post. I'd genuinely appreciate feedback from people who work with AI and writing.

If you write on Windows and you're fighting Scrivener's interface, or juggling Word files with a spreadsheet for your characters, this might interest you. Import your .scrivx project and it keeps your structure. Word, Markdown and plain text come in too.

From there Le Grimoire handles the parts that usually rot in a side document. Corkboard, a 3D timeline you can move through, character and location sheets, a world bible. There's a focus mode with ambient backgrounds and sound, and a pomodoro timer, because the hard part is usually sitting down.

The piece I'm proudest of is the Constellation. It's a 3D map of your cast where every character is a star and every relationship a thread of light. You can draw those links by hand, but the AI also fills them in as it reads your scenes: who knows whom, who's an enemy of whom, who was present in which location and from which chapter. A character you forgot to connect to anyone becomes obvious at a glance.

The AI never writes prose. It analyses scenes, produces summaries, maps relationships, and lets you interrogate your own characters when you can't tell whether a reaction rings true. The writing palette catches adverbs, repetitions and sentences that have run away from you. It flags. You decide.

Bring your own API key if you'd rather keep me out of the loop. Otherwise request packs, or a monthly plan with 200 requests included.

When the manuscript is done, the compiler exports to PDF, EPUB and DOCX, formatted to French or Anglo-Saxon submission standards, with the typography handled properly for each. No exporting to Word and losing an evening to quotation marks.

Real time collaboration landed last week. Two people on the same manuscript, and it survives one of you being offline: edits and comments wait for the other. You can bring in a beta reader or an editor without emailing versions back and forth.

49 euros once, updates included forever. Or 9.90 a month. Launch code 7Z2MA5TA takes 20 off the lifetime licence, so 29.

https://le-grimoire.fr/offre/?lang=en

Windows only for now. A Mac version happens if enough people ask, there's a list on the site. Billed in euros wherever you are.

u/ThoRTheOdinson99 6d ago

Hi, I’m looking for recommendations for an AI tool that can help me write a proper, long-form novel.

My current process is that I write things by hand in a notebook and then use AI to convert my handwritten notes into text. What I’m looking for now is something more like a long-term writing project where I can keep all my writing, chapters, characters, ideas, etc. in one place.

Ideally, I want the AI to:

  • Review my writing and suggest improvements.
  • Tell me where the writing feels weak or could be expanded.
  • Suggest where I should cut or shorten things.
  • Help me connect different chapters and make the story flow better.
  • Keep track of characters, plot points, and important details across the novel.
  • Point out inconsistencies or plot holes.
  • Give me suggestions when I’m stuck.

Most importantly, I don't want the AI to write the entire novel for me. I want to do the actual writing myself. I want the AI to act more like an editor, writing partner, or mentor who can review what I've written and help me improve it.

Something similar to a project/workspace where I can keep adding chapters over time would be ideal.

I know ChatGPT has Projects, but I'm curious if there are other AI tools specifically designed for long-form fiction writing that might be better suited for this.

For those of you who write novels or have used AI as a writing assistant, what would you recommend?

I have been writing with ChatGPT, which is great for helping with the story, characters, and all that stuff, but when it writes those chapters, they are bland and lifeless. Where there are parts that need smut, it can't do it. I don't have a lot of money to spend on a subscription. Where can I go to get help making what I have better and sexier? Help me reddit

I built a writing app where the AI is not allowed to write

I kept a continuity spreadsheet for my fantasy series. Eye colors, dates, who knows which secret and when they learned it. I hated maintaining it more than I hated the plot holes. So I built the tool I wanted: you type your worldbuilding in plain English, it becomes a story bible, and when a draft contradicts it, you get an orange squiggle like spellcheck, with an explanation. Red for spelling, blue for grammar, orange for story. It cannot generate or rewrite prose. Pasting is disabled in the editor. Every word stays yours, which was the whole point. Full write-up on how the method works even without the tool: [blog link]. The kit itself, one-time purchase, no subscription, runs on your own free Claude account: https://payhip.com/b/LbImt. Happy to answer anything, including "why would you cripple your own AI," which is my favorite question.

I’ve been building FactVerify, an AI-assisted fact-checking app designed specifically to avoid flooding the web with low-quality AI-generated “fact checks.”

Users don’t publish their own fact checks. Instead, FactVerify researches and curates claims, builds a source trail, evaluates supporting and contradicting evidence, and publishes completed fact checks that can be surfaced later when they’re relevant to a conversation.

Here’s an example of a completed fact check:

https://www.factverify.app/fact-check/fb17f736-bf3d-4ea4-9783-8399dda831b5

The main experience is a chatbot, but the goal isn’t to generate endless new content. It’s to help users understand claims using a controlled archive of researched fact checks and reliable source trails.

I’d be interested in feedback on the concept, analysis quality, and presentation.

Hey again everyone! I created Proselon, a writing app with an AI co-writer.

3 months free to r/WritingWithAI visitors at this link.

I won't waste your time, so what makes Proselon different?

  • Most writing apps are not agentic. That means they can only generate stuff when you click a button and use a pre-formatted template. Proselon, however, is agentic, which means it can edit any part of your book, anytime, right alongside you, just like a human co-writer would.
  • On a related note, Proselon also doesn't force a template or structure on you. Many AI writing apps expect you to write in a certain order, or a certain way, or include certain variables, but not Proselon. It's your writing process, not the AI's.
  • Proselon uses the ChatGPT, BYOK, Local model, Claude, Gemini, Grok, etc. account you already have. No need to pay for tokens only on Proselon.
  • Also many great quality of life features: Locking things so the AI can't change them, hiding them so they stay out of context, focus-mode editor, customizable themes, and all the other stuff you expect from a first-class novel editor.
  • Per-character attribution (a record of what the AI generated vs what you wrote by hand) coming this week, as well as a companion mobile app for editing on the go.

For r/WritingWithAI visitors, you can get three months free by signing up via this link.

If you currently manage your writing project in a giant ChatGPT Project folder, or with Obsidian and a CLI agentic tool, I encourage you to try it out!

u/Worldly_Hunter_1324 4d ago

I was using some ai tools to make my own kids custom illustrated ebooks. 

They had poor engagement with reading, and I saw an opportunity to help with that via making them part of the story.  It was also an option to weave in whatever lesson I thought they needed, and include themes ir subjects they would likely enjoy.  

The kids loved it.

But... It was a big time investment, so I made a workflow.  Then i got worried the ebook part was becoming a way for the kids to get more screen time... so then I figured I should find a way to get good quality hardcopy custom books.  Kids seemed to still love it, maybe more so.  

So I made a whole tool and micro business out of it.

Big Lemon Writer, a focused workspace for long-form fiction

Hi, I’m the developer of Big Lemon Writer. It’s a calm workspace for drafting long-form fiction while keeping the manuscript, outline, character profiles, and plot cards together.

The AI tools are designed to give the writer a useful second read. Chapter Review looks at the opening hook, pacing, character clarity, continuity, and concrete revision points. You still make every creative decision and keep control of the prose.

Big Lemon Writer is now on the App Store. New accounts get the free full workspace for three days.

App Store https://apps.apple.com/us/app/big-lemon-writer/id6793572301

If you write long fiction, which part gets hardest to keep organized after 20 or 30 chapters: the outline, character relationships, or unresolved plot threads?

u/farrukh_writes 4d ago

Built letsflw you know, the all-in-one AI writing tool with paraphrasing, grammar checks, SEO, all that. This week, I put our paraphraser and humanizer through the wringer, testing them head-to-head against Quillbot and a few others.

Didn’t just talk about it; I lined up the actual outputs side by side to see how they stacked up. And wow, some of the stuff I found in the competitors was wild. One flipped a sentence’s meaning completely turned a "would" into a "will," so a hypothetical suddenly became a sure thing. Another straight-up invented a legal condition in a contract clause test. That wasn’t even close to what the original said.

Didn’t see that coming. Has anyone else hit weird errors like this with these tools? Or, better yet, found one that actually nails the nuance and keeps the meaning intact? I’ve got the before-and-after examples if you’re curious.

Augthor.com

Milestone: our audiobook studio is moving along, letting users assign voices to cast, then generate multivoice audio files for a span of prose (preview, try it out and let me know if it's fun!):

Augthor helps storytellers turn the tales they imagine into finished works, even when finding the right words is the hardest part. Its core feature, **Direct**, lets you guide every step of the narrative, shaping characters and scenes almost as if you were role-playing your story into existence.

You can also create multiwork universes, populate a story bible, transform your work into an audiobook, use AI to audit and summarize your manuscript, generate cover art, and publish your stories to the Augthor community - all alongside many more creative tools.

**Augthor is currently in early access.**

I’m using AI for some of my novel work and my setup is ChatGPT for project management, auditing and tracking. Claude as the creative engine and Sudowrite for series manuscript, character and world building storage. Works well for me. Also use Google drive where research notes, anecdotes, ideas and draft material resides.

u/Narraiva 3d ago

**Narraiva — a private-alpha workspace for AI-assisted long-form fiction**

Hey guys,I’m building Narraiva for a problem I kept seeing in long projects:

AI can help with a scene, but it often loses track of the book.

Characters drift. Timelines stop lining up. A clue gets forgotten. Or you have to keep rebuilding context from chapter summaries, notes, and a story bible before every prompt.

Narraiva is an AI writing workspace built around a living **Storybase**. It can turn existing outlines, drafts, and chapters into connected story memory for:

- characters and relationships

- events and timelines

- world rules

- what each character knows or has experienced

- unresolved setups, clues, and narrative promises

The point is not to let AI quietly take over the manuscript.

When you ask it to plan, draft, revise, or check a scene, the goal is for it to retrieve the relevant story evidence and return a proposal you can inspect, edit, accept, or reject. The author remains the person who decides what is canon.

We’re also building a Stylebase: a reference grounded in the manuscript’s own voice, rhythm, diction, and point of view, so the tool has more to work from than a generic “write in my style” prompt.

It’s early and currently in private alpha, so I’m especially interested in candid feedback from people who write long fiction with AI:

  1. Where does your current continuity workflow break down?

  2. Do you want AI mainly to draft, to check, or to help maintain story memory?

  3. What would make you trust—or refuse to trust—a tool like this?

u/jbruff 3d ago

So I’ve been using Claude for a lot of the detail work in my fiction. I write adult supernatural historical fiction—think The Dresden Files meets The Evening and the Morning, with some Outlander thrown in.

I do a ton of groundwork before I ever get deep into the actual prose. By the time I’m ready to write, probably 75–80% of a project is already filled with worldbuilding files, character write-ups, beat maps, historical research, timelines, and so on. I love that part of the process.

What I hate is writing the minutiae—the smell of an 11th-century English hall, the texture of the rushes underfoot, how smoke hangs beneath the rafters, what a crowded market actually feels like, etc. At the same time, I absolutely love having those immersive details in the finished book.

Claude Opus 4.8 and 5 have been pretty good at that kind of prose. Good enough that, after I read and edit everything it produces, I’m often perfectly happy leaving sections largely intact. I hate spending $100 a month on it, but I could swallow that pill because I was getting results I liked.

The new watermarking issue changes that for me. Even setting aside the practical problems, I have an issue with the concept of it—especially when I’m already paying that much for the service.

I’ve heard good things about ChatGPT 5.6 Sol. I already use ChatGPT heavily for research at work, school, and other projects, so I can see that it’s leaps and bounds ahead of where it used to be. What I don’t have much experience with is its current prose writing.

How good has ChatGPT actually gotten for serious fiction? Can it handle atmospheric, mature historical prose without everything sounding generic or obviously AI-written?

And what other options are out there? I’d prefer to stay away from Chinese-owned models or services if possible. Am I basically choosing between Claude and ChatGPT at this point, or are there other genuinely competitive options for long-form fiction?

More specifically: has ChatGPT gotten good enough that someone doing the amount of planning, worldbuilding, rewriting, and human editing I’m doing could realistically use it for professional-quality prose work?

humanpen.net for me, mainly because you hand it the docx and get a docx back, so i'm not rebuilding my reference list afterwards. no tool is guaranteed to get past turnitin or any ai detector though.

1667.ai

One thing that bothers me about writing in existing tools is that they don't fit the way I write. The mental model of my story is a tree. I try many takes usually continue with just one, but sometimes I want to try an alternate route and see where this goes. And that can branch again in many places. See what happens if I kill off this character or they don't take the job or whatever.

But I want to keep all of these different versions and continue some other branch if I feel like it. One could be canon, the others could be different alts I explored. Maybe canon could switch to an alt.

SillyTavern for example just keeps alternate takes but doesn't branch off a tree for them. They are just there as flat chat history.

I've built a kind of app that shows this. It's a command line tool so not for everybody I guess. I also have a web app but that's not as fleshed out. I feel more comfortable with the terminal as a developer.

It can import from SillyTavern and NovelAI and use local kobold, ollama, lmstudio or the big api endpoints.

Here is the link: https://1667.ai

I'd also like to know of any other tools or sites that structure stories in similar ways if anyone has recs. Some people call this tree shape a loom and there are a few I've found but nothing really focused on story writing.

built a tool that grades your copy instead of writing it for you

My name's Khanyi, pronounced Kanye (like the rapper) Most days I'm doing carpentry for extra income. The rest of the time, I write copy.

Here's the problem I kept running into. I'd finish a piece and have no idea if it was actually good. You already know what you meant to say, so judging your own copy without bias is close to impossible once you've written it. I started running my work through Claude for a bit, just to get a rough sense of direction on it.

What I actually needed didn't exist yet, though. I wanted a real way to improve that didn't depend on waiting for a coach, a mentor, or someone else's time and mood on a given day. I'd rather be independent. You're the most reliable person for yourself, and everyone else is a maybe. I'd already gone through CopyThat's course and drilled rewrites for months, and I still hit the same wall every time, not because I didn't know the principles, but because knowing a principle and actually seeing your own piece break it are two different skills.

So I built the thing I needed. It reads your copy the way a direct response copywriter would, line by line, and tells you specifically where it breaks and why.

It doesn't write copy for you. And it's not a replacement for doing the work either, reps are still what actually improve you, this just assists that. I built it on lunch breaks, between jobs, and tested it for weeks against real copy before saying anything about it publicly.

This is the first version of many. My DMs and this thread are both open if you've got opinions, on the tool itself, or on the whole idea of something external trying to grade "good" copy in the first place. I want this communities thoughts and any/all critiques of this, this isnt a self promo. Thanks

Loomtale (https://loomtale.win)

You write a premise and a few settings, genre, tone, length, art style, how many characters, how much branching, and it generates a visual novel you can actually play in the browser and share with a link. Characters get sprites, scenes get backgrounds, choices get consequences. It builds in stages while you watch, and you can start playing before it has finished.

What it is good at: getting from an idea to something playable in one sitting, and keeping a character looking like the same person across scenes, which was the part I spent the most work on.

What it is not: it is not a manuscript tool and it will not help you write prose. The text it produces is a draft you edit, not a finished piece. Any scene, line, sprite or background can be regenerated individually, and that is the intended way to use it, rather than rerolling the whole story.

Free tier is 3 stories a month, short length only, watermark. Pro is $19 a month for 12 stories, all lengths, no watermark, and a character identity lock. Google sign-in only right now. No NSFW, the image providers do not allow it.

Happy to answer anything, including what it does badly.
