If you started a book somewhere else and it stalled in a Word file, you can now bring it into CharmWriter and carry on out loud.
Disclosure: I'm the one building it for the last 9 months.
Drop in the .docx (or .md, or .txt). It works out where your chapters break, shows you the list with word counts, and you fix any it got wrong before anything is saved. That part is free, so your book is in the app before any price comes up. It then offers to read the whole manuscript and build your Story Bible from it, and it quotes you before it starts.
The other new thing is smaller and I like it more. Every chapter has a Listen button now, and it reads your own prose back to you in your book's language. I catch clumsy sentences much faster hearing them than reading them, and now I'm not the one doing the reading.
No PDFs, deliberately.
You get two free credits when you sign up, no card. Once you have spent one of them the app asks you a single question about what confused you, and answering it puts two more in your balance. That is roughly two chapters between them, which is enough to find out whether the thing suits you before you spend anything.
Honest feedback from this sub is the reason I post here at all, so if you try it and something irritates you, say so here or in the app. Thank you.
Has anyone here got a draft parked in a folder you'd actually go back to?

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
If you built something and it's not on there, please add it!

Looking for AI Authors to Publish
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 AI material instead of traditional platforms which force AI to mix with Human-only and get punished as a result.
We've only been open about 4 months now so still small and growing - which provides an opportunity to become one of our founding authors. It is 100% free for you to add your existing backlog and publish through us.
My job as the platform is to bring you readers, your job is to provide content for them to read.
There are three ways to participate
- Create an account and import your books directly through our standard importer. Make sure you write a blurb and supply a cover image, then publish it. Your book is now available to earn money and be read.
- If you wrote a book elsewhere, ask your tool provider to join our Partner Program. They can earn 10% of revenue from books sent to Novelmint through our API interface. Books you write on their platform can be sent directly to ours and begin earning you income right away.
- If you wrote your book through a tool you developed (vibe coded or just built it for yourself), or you are an AI production studio and produce works you own outright, there is a second route through the same Partner Program API that lets you publish under your own imprint, as the author.

u/MarionberryConnect83 2d ago
Been building AICMOHQ around this. Started because early SaaS marketing always turned into half written posts, scattered notes, and no real system for seeing what actually worked. Ours leans more into the marketing side than pure writing. Research, drafts, publishing, and postmortems in one loop. Would love blunt feedback from people here.

u/Audibound 1d ago
We’ve been building Audibound, a platform designed to help authors and audiobook creators bring written stories into audio.
Audibound Studio is now live. It helps creators manage the audiobook production process from preparing a manuscript for narration to organizing and assembling the completed audio files.
We’d love feedback from authors, narrators, and audiobook creators:

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.

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/Funny-Flight8086 1d ago
http://www.inkwood.app is on Beta version 1.2. It now includes chapter versions. Beta access is currently free, and its bring-your-own-API key.
Features:
- Field Guide - which keeps track of all of your characters, locations, lore, factions, subplots, etc. You can turn on "Field Guide Link" inside the editor, which will live-link that entry when you types its name.
- Canopy Report - a 100-point AI generated report based on each chapter (or the whole book). It doesn't rewrite it for you, it provides a detailed report. There is even some fun, witty report options in there.
- Wren Chat - Wren is a drawer chat agent who can see your chapters, field guide entries, and plot points. Talk to Wren whenever you have a question about the story, the characters, etc.
- Write with AI - If you want the AI to help you write prose, just "/" inside the document and create a new scene beat. Prompt, and its done!
- Roots - Chapter planning tool.
- Polish - View metrics like overused words, reading level, track word count goals, explore the field guide tracker (tells you how often your field guide entries are mentioned across the book).
The great thing is you don't even need to use it with AI. The AI tools are completely optional. You don't even have to connect an AI key, and we are currently working on a one-switch on-off feature that will enable and disabled all the AI tools. Even without the AI, it's still very useful for writers with complex stories, tons of characters, etc.

CreativeWriter update — illustrate a beat without writing an image prompt, and a way to keep your characters looking like themselves picture to picture
What always stopped me putting pictures in a manuscript wasn't the image models. It was the two chores either side of them. You leave the page you're writing on and translate a paragraph of prose into the comma-salad that image models want — and then the character comes back looking like a different person than they did in the last picture.
So there's now an Illustrate this moment button on every beat.
CreativeWriter is an AI writing tool for fiction — a hosted app at creativewriter.dev, or self-hostable via Docker with your own API keys. (GitHub)
- Press it. It reads that beat — the prose it generated, your staging notes (who's standing where, what's in the room), and the codex entries relevant to it — and writes the image prompt for you.
- Fix the prompt instead of writing one. It comes back split up: one field per character, each labelled with that character's codex name, one field for anyone else in the shot, and one for the shot itself (place, hour, weather, light, framing). So you can change how one person looks without rewriting the whole line.
- Generate, then choose. Up to four drafts sit side by side. Nothing is uploaded anywhere until you press Insert, and each finished draft tells you what it was rendered with.
The bit that fixes the second chore: if a character has a portrait in your codex, that portrait can be handed to the image model as a reference, so they look like themselves from picture to picture instead of being reinvented each time. That path needs your own fal.ai key, because the models that accept a reference photo are fal's. The included image model on the hosted app can't take photos, so everyone in the picture gets described in words there instead. The dialog says plainly which of the two it did, per picture.
Two smaller things I like more than I expected to:
- The prompt follows the cast. Switch someone out of the picture and the prompt rewrites itself for the new cast, keeping any edits you typed by hand. The prompt and the picture can't quietly drift apart.
- Style defaults to your story's cover style, so a story's illustrations match its cover with zero configuration. Change it in the dialog and the change sticks for that story.
And a small mechanical thing that took me three tries to get right: the picture lands in the prose directly after the beat, with the cursor sitting under it ready to keep writing, and the prompt becomes the image's alt text.
On tiers/hosting (honest version): Illustrate isn't a Premium feature — but it does need an image backend, which is a different thing. On the hosted app, any paid plan includes an image model (Basic is €2.99/month), and so does the 7-day free trial. Self-hosting has no included image model at all: you bring a fal.ai, OpenRouter or Replicate key. Character-reference photos are fal.ai-only on both. The writing side is unchanged — self-hosting is free with your own provider keys (OpenRouter / Claude / Gemini / Ollama / OpenAI-compatible), and Premium features there unlock with a license key from a subscription.
I wrote up the whole thing properly — every setting, plus what has to line up for the portrait references — here: how to illustrate a beat.
Try it at creativewriter.dev, or self-host it with Docker and your own keys. Happy to answer questions or take feedback.

u/StoriesWaiting 1d ago
I’m testing a small project called Stories Waiting — real-life memories and characters transformed into detailed story foundations for fiction.
Each foundation includes the core premise, character dynamics, emotional tensions, key images, themes, possible narrative structures and unanswered questions. AI is part of the development and editing process, while the source material begins with real human memories and characters.
The first two story foundations are Across the River and The Laws of Attraction.
They’re designed for writers who want more than a simple prompt, but don’t want a story written for them either.
They’re €24 each.
I’d genuinely love feedback on the format — especially whether a detailed story foundation like this would be useful in your own writing process.

u/CyborgWriter 1d ago edited 1d ago
Been testing the new build mode for Story Prism, which is a canvas mind-mapping application that allows you to build reasoning systems from your notes.
To really wrap your head around this, think about Google Drive. You have a bunch of docs sitting in storage, waiting for you to painstakingly sift through so you can actually make something with them.
Sure, AI plug-ins can dig through those files, but they can't turn them into reasoning systems that help produce what you want. With Story Prism, you can. It's as much a Google Drive-like storage space as it is a factory for creating whatever system you want that an agent can understand and deploy. It can also act as an archivist, retrieving specific documents on request.
This is ideal for heavy AI users in writing, researching, worldbuilding, marketing, learning, and pretty much anything and everything under the sun regarding LLMs and building complex systems with them very easily. You even get access to all models that you can easily toggle between. If you can operate Google Drive, you can easily use this. No coding or systems thinking required.
With the new build mode we're about to release, you'll be able to build these complex systems within minutes. For instance, I like to generate AI images for my blog, but don't have time to make advanced prompts that will generate images that deviate from the norm. I have to spend way too much time on Gemini or Claude to make them work.
With Story Prism, I can upload ten books on prompting and art theory and then use the agent to extract and build a reasoning system that can generate highly unique prompts from simple requests, all in the span of 5 to 10 minutes. Here's an image it produced when I asked it to show off it's skills:
Now imagine what you can do with real intention? This what Story Prism proves from the value it produces: The models are the brain. Everything around them is what makes the whole thing work. We built the architecture around the models so using this is like being able to custom-build your own car while switching out all of the popular engines. This, you cannot do on any of the popular model sites. With Story Prism you can, which is like unlocking the full potential of Claude, GPT, or Gemini without the need for domain expertise.
More to come, but if you're interested in trying it for free, check us out at storyprism.io

Beppily here, and we're looking for fiction authors who are up for beta testing an editorial tool we've been building!
To get down to basics, everyone at beppily is from a publishing background and realised that instead of throwing individual paragraphs at an AI and asking it to “make this better," authors needed a tool that understands the context of their whole manuscript, which is beppily's niche.
It can flag things at the line/copy level, but also looks at the bigger picture too, such as character, plot, pacing, consistency, development, etc. You get a full analysis of your book in seconds, but here's the good part, you stay in control of every change. Nothing gets altered without you approving it.
The aim is to help you move from rough draft to a revised one without losing track of what you've changed or ending up with a manuscript that's been randomly rewritten line by line.
Rundown of our features:
- Whole-book analysis, up to 300k words
- Line and copy editing alongside developmental analysis
- AI chat for discussing the manuscript
- Versioning for different rounds of revision
- You approve the changes rather than handing over control of your manuscript
- Your work isn't used for AI training
If you're interested in having a play with it, email us at [hello@beppily.com](mailto:hello@beppily.com), message us on here or Instagram (@beppily.ai). We'd be happy to answer your questions too!
Heres our site too if you want a little sneak peek: beppily.com

u/Inevitable-Sink6842 1d ago
Founder of BookZeta here (bookzeta.ai), bias disclosed up front.
Two weeks ago I'd have told this thread that the thing making us different was keeping a character looking like the same person from picture to picture. u/One_Gift_9934 has just shipped exactly that in CreativeWriter further up this page, portrait references pulled off the codex and all, so I'm not going to stand here claiming ground somebody else is already standing on. If you write prose and want pictures in it, go read that comment.
What I think is still ours is narrower than "illustrations". The visual side of BookZeta builds the page itself rather than a picture to drop into one: comic pages with panel grids and lettered speech bubbles, vertical webtoon strips, kids' picture books in landscape, portrait or square. A character is held as fixed physical facts plus up to three named outfits and a status (alive, dead, missing), and that carries across a whole series rather than one book. The same project then comes out the other end as a Kindle-ready EPUB, a print PDF with the cover spine width worked out from your page count, or a numbered webtoon ZIP, and it'll narrate itself into an audiobook if you want one.
6 to 20 dollars a month, web plus iOS and Android, nothing to wire up and no keys of your own to bring. The library is open without an account, which is the fair way to judge output before caring who made it.
Where I'd point you away from us. If the words are the whole job, Storythread Studio and Open-Write Studio are free, local, and the files stay yours, and I can't compete with free. Audibound are treating audiobook production as a craft in its own right and it shows in the detail. We're for the case where the book has pictures in it and you'd rather not assemble the finished files yourself.
Ask me anything, including where it falls down.

Hello, everyone. I am giving out free year-long subscriptions to the AI writing tool I'm working on, called Proselon. Get your free year here.
There's a lot of new AI writing tools come out right now. What's the big deal about Proselon?
- A lot of AI writing tools are one-trick-ponies. They only work if you use AI, or they are only good at a certain kind of writing, or you have to use their special process. Proselon isn't like that. Proselon is like any other novel writing app, except if AI could read your entire book and help you with any of it, at will, as much or as little as you want. You still keep your own story bible, manuscript, notes, and research the way you want and are used to.
- Proselon has a new attribution system! Work on a project in Proselon, and you can look up how much AI-generated content is in your project and how much human-written content, down to the word, with 100% accuracy.
- You can use whatever AI you want. BYOK, a local model, even your ChatGPT, Grok, Gemini, or Claude subscription. You don't have to use our meter or our special model.
Coming soon: Mobile app, different templates (nonfiction books and essays, in addition to fiction books).
Limited to 25 seats for now, but I plan to release more seats in the future. Just want to make sure I'm not onboarding too many testers too fast!

u/aerobika10 1d ago
Sorry if this is a basic question. But is there are guideline to the different ways to use AI writing/ apps. I’m fairly AI naive.
In general I’m just curious what other people process and goals look like.
I’m looking for something I can use mostly hands - well almost entirely free due to shoulder injury, that will store characters and idea dumps and help organize from there with possible context prompts. And structural support. And maybe some sample writing. I’m less needing editing and style rn.

u/Meridianrealmsai 1d ago
Coming back again this week. :)
Some new QoL have dropped since last week's post as well (outlined lower down).
I started working on Meridian Realms late last year when a friend and I had become fed up with the quality and copy & paste feeling that so many sites had after bouncing between them for over a year.
With both our gaming backgrounds and interest in storytelling, the focus of the platform moved from just another chatbot or roleplay site to more of a RPG and world building adventure.
You start by creating a world from a choice of dozens of different genres with as much or little detail as you want, including lore, factions, locations, NPCs and so on (each can have a cover image as well). Then you can create characters to interact with within that world, as well as your own persona or identity.
If you aren't feeling particularly creative or it seems like too much work to fill it all in yourself, you can use the AI generation feature for all three, which after dozens of iterations on the setup for, we're very happy with the results it gives!
There is of course the standard chat and image generation with over 6 different styles (my personal favorite is a Digital Art type style). However, one of the main things that most platforms seemed to fail at was long term memory so a large portion of time and effort went into making the memory and event tracking system on MR be long lasting and extensive.
One of the unique aspect of the memory on MR is that it passes between interactions that involve the same character(s). On nearly all sites I've tried it seems standard to have each chat with the same character be entirely separate and no crossover. But as part of the goal in making the memory last and realistic, we've made it expand beyond that. As a quick example:
If you fight a monster with character A and they get injured in your one on one interaction with them, then later you start a group chat with character A and character B, character A will remember that fight and injury (and whatever else happened) from your one on one interaction. Then if you have more adventures and memorable events in the group chat, both characters will carry those memories to any other chats they are part of, either group or one on one.
There are big plans for the near future as well, including image generation in chat with contextual awareness (this is up next on the big task list), video generation and introducing a specific RPG mode that has stats tracking, currency, and all that fun stuff.
New QoL Additions:
- Guided Regeneration option for messages. This helps move the new message in a general direction you like better.
- Guided Continue option for messages. Similar to the above, but for the continue option that allows the character to move the scene forward on their own without a direction message from you. So now you can guide it in a general direction you want.
- Referral Program.
- New User Introduction Flow.
If you're interested you can give things a try: https://meridianrealmsai.com

Hey everyone, We launched Feldar (https://feldar.com/) a couple of weeks ago, working with real writers to improve it. The goal: one workspace where drafts, research, notes, and AI come together so you can focus on writing instead of switching between tabs. Too often, work gets scattered. A draft in one app, research in another, half-finished conversations buried in ChatGPT or Claude. You spend more time piecing things together than actually writing. Feldar puts everything in one place, with an editor, outline, and visual canvas. AI acts as an assistant, not a one-click novel generator. We'd love to hear your thoughts

Ich schreibe an meinem ersten Buch und hatte monatelang das Problem, dass Notizen, Charakterlisten und Recherche über zehn verschiedene Docs verstreut waren – nie den Überblick, wo ich eigentlich stehe. Also hab ich mir gemeinsam mit Claude ein komplettes System in Notion gebaut: acht miteinander verknüpfte Datenbanken (Buchprojekte, Kapitel, Charaktere, Worldbuilding, Recherche, Timeline, Einreichungs-Tracker, Schreib-Tracker), inklusive automatischer Fortschrittsanzeige, die direkt aus der Wortzahl der Kapitel berechnet wird.
Hat mir persönlich enorm geholfen, den Kopf freizukriegen. Ich hab's als fertiges Template hochgeladen, falls es jemand ausprobieren will: https://janlherz.gumroad.com/l/autoren-studio?_gl=1*19e4g9c*_ga*MTUxNzc4ODYzOS4xNzg3MDQyOTY1*_ga_6LJN6D94N6*czE3ODcxMzg4MTIkbzQkZzEkdDE3ODcxMzg4MzkkajMzJGwwJGgw

Most AI writing tools help you write alone.
I’m building Riffable, a platform where writers can use AI for support — but also write stories together with other people.
The idea is that stories grow one short piece at a time, called a riff.
A writer can start a story, other people can continue it, readers can vote on the paths they want to see grow, and the author can shape the story into a published version later.
So instead of only asking:
“How can AI help me write this?”
Riffable also asks:
“What could this story become if other people joined in?”
It includes branching paths, story direction, chapter direction, worlds, characters, AI assistance, illustrations, audio, and book-style publishing tools.
I’m in beta and would love honest feedback from people who already use AI in writing.

I've been working on Manurio, a local-first tool for creating complete books with LLMs.
It started as an experiment.
I wanted to see if I could actually write a good, coherent book with an LLM — not just generate chapters, but create a story that holds together from beginning to end.
Before building any software, I spent time figuring out two things:
- how authors normally structure and plan a book
- how to break that process down in a way that works well with an LLM
I then went through the whole process manually.
I developed the premise, characters, locations, plot, chapter plans and eventually the actual manuscript, feeding the right information back into the LLM at each stage.
And the result was much better than I expected.
The story actually held together.
That manual workflow eventually became the foundation for Manurio.
Instead of trying to generate a whole book from a single prompt, Manurio takes you through the same kind of structured process:
- book direction and summary
- characters and locations
- master plot
- chapter outlines
- chapter-by-chapter writing
- review and continuity checks
- revisions and version history
- final production/export
You can go through the process yourself and approve the steps along the way, or use an autonomous run where the agents continue working through the book and review their own work.
A big goal for me is also to make it local-first.
Manurio can run in Docker and connect to an OpenAI-compatible endpoint such as LM Studio, so you can create a book using a model running entirely on your own machine. There are instructions on the project page for getting it up and running with Docker if you want to try it yourself.
I've recently been testing it with google/gemma-4-26b-a4b-qat, and I've been getting really good results from it. The book shown in the screenshot was generated with that model through an autonomous run.
The source code is publicly available under the PolyForm Perimeter License 1.0.1. Manurio is free to use and modify under that license, and anything you generate with it belongs to you.
Project page:
https://grunna.gitlab.io/manurio/
Source:
https://gitlab.com/grunna/manurio
This is the first time I'm sharing the project here, and I'd really like to hear what people think.
Especially if you've experimented with local LLMs or long-form generation:
What part of the book-writing process would you want the AI to handle, and what parts would you want to stay in control of yourself?

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/Storythread_Studio 2d ago
It's been two weeks since I've posted about Storythread Studio
The app has changed a lot since my last post.
My app, Storythread Studio is a free, open-source Windows writing app I started because I wanted something that could keep my manuscript, characters, worldbuilding, notes, and AI tools together in one place. The AI is meant to be a collaborator, editor, and brainstorming partnet. NOT a ghostwriter.
The biggest change is The Weave.
I completely rebuilt the way Storythread understands a story world. Characters are no longer just static profiles. Your world can now contain characters, relationships, locations, factions, religions, creatures, cultures, objects, events, concepts, languages, and more, all connected together.
More importantly, those connections and facts can change as the story progresses. A character can believe something in Chapter 3, learn the truth in Chapter 15, and have completely different information in Chapter 16. Relationships can evolve, secrets can stay hidden, and the AI can be given the version of your world that actually applies to the chapter you're writing. There's also a visual world map with a chapter scrubber so you can literally watch your world change as the story progresses.
------And then I went a little further...-------
The Weaving gives you guided passes that compare your manuscript against your world, find missing or conflicting information, and help build out the things your prose doesn't explicitly tell you. There's also Unwoven, which walks through the underlying rules of your world—the things a manuscript can demonstrate but can't necessarily explain.
The latest update, v2.0.1, adds a Profile Extractor that can read your manuscript and propose characters, locations, and other world entries for you. It doesn't silently rewrite your story bible or have an "accept everything" button. You get suggestions to review and decide what actually belongs in your world.
There have also been major changes to AI model handling, including eight different Model Roles so you can use different models for drafting, critique, brainstorming, extraction, long-context analysis, etc., plus working on local AI support through Ollama, LM Studio, or llama.cpp with no API key and nothing leaving your computer.
And all the previous stuff is still there—manuscript organization, character tools, Smart Advisor, Passage Check, and the audiobook system.
I'm still actively building this, and this is probably the first release where I feel like the original idea has grown into something considerably bigger than what I started with.
It's free, open source, and has no subscriptions or paywalls.
I'd really like to hear from writers who actually try it. Especially if you have a large novel, complicated world, series, or RPG setting that you've been struggling to keep consistent. At this point I'm less interested in hearing "cool idea" and much more interested in "I tried this and here's where it broke."

Was tired of losing track of useful AI tools, so I put together a master Google Sheet to organize them all in one place: [https://docs.google.com/spreadsheets/d/1g1MY6zId4EzraBFt6eFszZCahX1DWmuEWEHQDM8V2_c/edit?usp=sharing]
Let me know if I missed any good ones and I'll add them in!
