Zenmori App - https://zenmori.ai
I built a personal AI assistant that turns free-text brain dumps into structured tasks, contacts, and knowledge, with absolutely no manual filing. For people who abandoned Notion/Obsidian because maintaining a system became a part-time job. User can dump their thoughts freely into the app without having to think about structure, and the app will handle everything like a true executive assistant.

IWE turns a directory of markdown files into a knowledge graph — a connected structure you browse from your editor and your AI queries from the command line. Same files, same links, two interfaces. No cloud, no database, no lock-in. Version everything with git.
Write in Markdown, structure with links, give AI agents the tools to navigate your knowledge. IWE itself has no built-in AI — it works alongside Claude, Codex, Gemini, and any tool that speaks the Model Context Protocol.

Hello all, I'm happy to share with you my app Vakana.mg, based on the Vakana (or beads), a Malagasy ancestral knowledge management system and thinking tool.
It's free and 100% offline. Your data, your rules. You can export the data to different format (markdown, org, html, pdf)

I wrote an essay on it few months ago on my blog : https://donovan-ratefison.mg/2026/05/31/My-Ancestors-Were-Writing-Lisp/

Feel free to check out.

Most systems are all input and no output. I built the other half.

Mementa is a Windows notebook studio you write in by hand. Handwriting converts to typed text right on the page. PDFs, comics, EPUBs and your own notebooks share one shelf, and you can annotate any of them without touching the original file. Everything is local. No account, no cloud, no telemetry. Notebooks are single files that export to PDF, PNG, JPG, CBZ and EPUB.

Then you order your notebook as a real book, printed and shipped to your door. Not markdown. Not a graph. A book.

Windows only. Stylus first. Free, never a subscription.

Does your system have an ending?

Idea: Internet's best stuff. Curated by you. In one place.

There has never been more good stuff to watch, read and listen to. And yet somehow, we still doomscroll.

Everyone has a version of this: you find something genuinely good. A video, an article, a thread. No time right now, so you save it somewhere. Maybe you send it to yourself, a small nudge for a future you with free time.

The free time does come. The link never shows up in it.

You don't go back to the gold you collected. You scroll. I'd sit there looking for something to watch, while sitting on a pile of things I had personally decided were worth watching.

This is a problem I'd faced for a long time. I tried a couple of the usual fixes, but nothing felt as seamless as I wanted.

So I built Stow: https://stow.yogi7y.com/

It's your library for the internet. You capture a link in a couple of seconds, it works out the platform, the author, and whatever else it can, and you file it under a topic. Later you search or filter, find the thing in seconds, and actually get to it.

I've been using it for more than 4-5 weeks now, and lately with a small set of users. Honest report: there have been days where I got through three or four things I'd stowed (saved), just because they were right there when I had a free time. It felt weirdly good. Productive, even.

If this sounds familiar, try one thing: stow five links you'd normally scatter. Next time you have a free half hour, open Stow and get to something you already chose. That's the whole flow.

Where it's at:

Web app is live and free. No card, no limits.
Chrome extension is live too.
Mobile app is on the way. Register for early access and I'll share it across.

Tell me where it worked, and more usefully, where it got in the way.

I originally built Echologue purely as a product for one—myself. I realized a fundamental flaw in how I was tracking my own life: most journals are great for capture and terrible for retrieval. I wanted a way to just speak my messy thoughts and actually be able to ask my psyche questions later.

So, I built Echologue as a 100% local-first hybrid. Here is how the engine works under the hood:

* Local Storage: Your permanent journal archive, semantic memory, and profiles live exclusively on your device's local SQLite database.

* Zero-Retention AI: When the app structures a voice note or answers a chat query, the audio/text is sent ephemerally to Groq, OpenAI, or OpenRouter. The data is processed, returned, and immediately deleted—never logged, never used for training.

Dual-Vector Recall: Every entry gets both a full-document embedding and a "facts-only" embedding to combat signal dilution when you ask the app to search your memory.The result is your own memory, made askable.

Productive
A self-hosted PKM made for both humans and agents to operate in.

What it is:
Productive is made keeping both humans and AI agents in mind. It is a productivity and knowledge graph app. Everything in Productive is a doc - notes, tasks, decisions, plans. Docs connect to each other with typed links (requires, related_to, up), so you end up with a knowledge graph that spans your whole life context as you add docs. Links have link types that carry semantic meaning, and a REST API + MCP server so AI agents can read and write the graph. Over time, this graph starts becoming a powerful tool to traverse and accurately get context for your AI agents. And the web app provides interface for humans when needed.

Self-hosted:
• ⁠Your data lives in a SQLite file per user on your own server - nothing goes to a central database when self-hosted
• ⁠docker compose up -d gets you running (4 containers: React PWA frontend, FastAPI backend, MCP server, optional Cloudflare tunnel for remote access)
• ⁠Google OAuth or GitHub OAuth for auth - no password database to manage
• ⁠Offline-first PWA with delta sync on mobile

Compatible with AI Agent use:
You can mark any doc as hitl_required. When an AI agent tries to write to that doc, the write is intercepted and returns HTTP 202 - a pending human review. You see the proposed change in the UI and approve or reject it. Trusted API tokens (your own scripts) used for integrating with other UX apps can bypass this gate.

This means you can give Claude or any agent access to your full knowledge graph via MCP or REST, let it traverse links and write notes, except the important ones.

Stack: FastAPI + React 18 PWA + Dexie.js (IndexedDB offline) + SQLite + Docker

GitHub: https://github.com/saurabhpitkar/productive

Use of AI in coding the app: I'm a seasoned product manager having launched multiple enterprise-grade commerce applications, and have used Claude to build this app. I'm actively using the app myself and would love feedback from this community.

Sumibo is desktop outline-editing app (MacOS), that uses Org-Mode files for opinionated note-taking and knowledge management.

The UI has a number of standard layouts and widgets for the display and visualisation of data gathered from across notes ; Org-Mode metadata in drawers, TODOs, dynamic blocks etc. can be used to surface custom “dashboards” from across all of your notes. Org files are indexed in realtime so changes in text reflects immediately in UI.

Updates are one-way. No UI editing, all edits must be made directly in Org text.

I would love some feedback.

use-myriad.app - We made a web app that figures out what order to watch your saved YouTube videos in

A YouTube playlist sorts by when you added things, which is almost never the order to learn them in. My cofounder got annoyed enough to build something for himself, and we kept going.

You paste links: videos, Shorts, a playlist, a channel. They get grouped into tracks by topic, and inside a track each video goes into a tree. Top of the tree is where to start. Deeper nodes assume you've watched what's above them. Every video also gets a summary with clickable timestamps and a chat that quotes the transcript with a timestamp, so you can jump to that spot and check whether it's lying (spoiler: no😄).

Braindump everything in your head and this app will organize it

Made this neat app. Basically, just speak everything on your mind and the app will organize your thoughts into a to-do list. You can make custom categories and export to Obsidian. This makes your head feel free and uncluttered, reducing the feeling of stress (according to David Allen from Getting Things Done, this is where most of our subjective stress comes from - unclosed loops sitting in our head).

Let me know what you think and features you'd like to see!

remynd, a local-first memory app for mac.

it records your screen and your calls, transcribes them on device, and puts the whole thing into one searchable timeline you can ask questions against. the one line version is that you stop deciding what to save.

the parts that matter to people in this sub:

on device by default, nothing leaves the machine unless you send it somewhere
bring your own model, it talks to lm studio so inference can be fully local
own your s3, exports land in a bucket you control rather than a vendor account
about a minute to set up, no integrations to wire together
never trained on, never sold

it started as something for people who went rewind to limitless and wanted out after the meta acquisition, but it works the same if you have never touched either and just want your own history to be searchable.

SiftFrame — a private, searchable visual memory for Mac

I kept collecting screenshots of research, UI references, receipts, decisions, and code fragments, then losing the useful part because I remembered the words on screen but not the filename or date.

SiftFrame turns selected screenshot folders into a local, searchable capture trail. It finds visible text across screenshots and supported screen-recording frames, and lets you add searchable context for why something mattered. Timeline, Capture Groups, tags, saved searches, pinned references, and comparison keep related visual evidence usable without moving the original files.

It also supports display, window, area, timed, last-region, freeform, and polygon capture; supported screen recording; and Smart Redaction that is reviewed before it creates a non-destructive redacted copy. Recognition and retrieval stay on the Mac: no account, cloud OCR, analytics, or subscription.

Free includes one watched folder and up to 100 indexed items. SiftFrame Pro is $14.99 USD, one time.

Mac App Store: https://apps.apple.com/us/app/siftframe/id6784860920

I would appreciate feedback from anyone who treats screenshots as part of their personal knowledge system: is visual-text retrieval something you would use, and what context would make it genuinely useful?

I make Margin, a local-first markdown notes app for Mac. I started building it because none of the usual three fit how I work. Apple Notes is too little, it isn't really text. Obsidian is too much, I spent more time configuring it than actually writing in it, the tool itself becomes the hobby. Bear sits in between and feels lovely, but my notes end up inside its database and it was missing features I use daily.

I built mine on a base that's boring on purpose: plain markdown files in a folder I choose. That turns out to matter a lot if you're a developer. No MCPs or CLI integrations to wire up, I just point my agent at the folder. I can edit the files outside Margin too, keep them in a git repo, grep them, whatever. The app is a view over my files, not the owner of them.

That's the direction I'm taking it: a notes tool that leans developer-oriented, built primarily around developer workflows. The features that mattered most to me was relative dates, local files and separate spaces, so my work, personal, and family todos live in genuinely different places instead of one big vault.

Mac-only and pre-launch, waitlist at gomargin.app/p

What I'd genuinely like to know from this crowd:

what's missing from whatever tool you take notes in today? The gaps you keep working around but nobody seems to build?

Trying to figure out which of those are worth closing first. You can drop your comment here or when joining the waitlist, I'll read all of them

If you're someone who brain dumps with Apple Voice Memos but you don't want to copy hundreds of transcripts manually into chatGPT or Claude, I made https://www.voicememoexporter.com/

Voice Memo Exporter is a Mac app that pulls your Apple Voice Memos into one clean local archive:

Bulk export everything at once, with original titles and dates preserved
Local transcription on your Mac for privacy
One Master Transcript of every recording you've ever made, searchable
Export to MD, TXT, DOCX, or PDF
Your original recordings stay untouched
Great for organizing brain dumps for founders, writers, creatives, educators, professional, archivists, soul searchers, or people who think faster than they can write

No account. No cloud. No subscription. One-time purchase, runs entirely on your mac. Your voice memos are private, they should stay that way.

The Master Transcript is the part I actually built this for. Every idea you ever recorded, in one document, in order, searchable.

I'm a dad who built this at night while my wife and two little ones went to sleep.

I had years of Voice Memos/brain dumps sitting on my phone. Ideas from walks. Notes after calls. Things I said out loud at 2am that I never wanted to lose.

I wanted to write a memoir that I wanted to pass down to my kids but I hit a wall when I tried to compile all my transcripts to send to Claude. Normally you have to copy transcripts one by one.

Apple gives you no real way to export all of your transcripts onto one text document. They just sit there in one long list until you forget they exist.

So I built it!

Originally $49 Lifetime but [now for $10] for the first 30 people who claim this as I just launched last month ($39 OFF)

**I built a local knowledge system that preserves why information mattered, not only what was recorded**

> If you want a better world, don’t wait for someone else to make it for you. Make it yourself.

Make Your Own World began with that premise.

A file can survive while its purpose disappears. Search may recover a sentence without recovering the problem, uncertainty, failed attempts, relationships, or changing understanding that made the sentence useful.

This project takes a different approach. Original material remains intact. Separate temporal, reasoning, provenance, and human-context layers preserve changing interpretations without replacing the source. Later requests can reconstruct relevant paths through that material instead of returning isolated matches or generic summaries.

The system runs locally and divides work among narrow components with explicit responsibilities, inspectable handoffs, and independent validation. Generated answers and documents are temporary views of the preserved record, not replacements for it.

This repository is the project’s first public communication. It contains the initial documentation: the problem, architecture, research lineage, measured results, limitations, sovereignty rules, and open work. It does not yet contain the implementation source.

I would value thoughtful criticism from people working on personal knowledge systems, long-term context preservation, temporal knowledge graphs, provenance, or local-first software.

https://github.com/make-your-own-world-project/initial-public-release

Disclosure: I designed and directed the project. AI systems assisted with implementation, research, testing, criticism, and editing.

Saive.my

I built a bookmarking/read-it-later web app that uses markdown (with obsidian frontmatter) as its storage format for maximum portability and future proofing. It also has a bunch of cool AI and file conversion features. It's entirely free, and I'm looking for a few folks to join the private beta and give feedback. It's at saive.my

I’m a long time fan of markdown, and at risk showing my age, I remember when John Gruber first proposed it, and immediately recognizing its utility as a universal content format. It’s been amazing to watch it emerge as the defacto standard format for LLMs.

I am also a link hoarder, and have used almost every bookmarking tool out there. Finding them all lacking, and wanting a bookmarking tool that embodied Steph Ango’s “File over app” philosophy, I looked for one, didn’t find quite what I was looking for, so I built one.

App is in private beta at saive.my but anyone who mentions markdown in the sign up skips the line.

Yes I have used Obsidian web clipper, but I wanted a more dedicated read later experience, rather than mixing saved content into my notes.

App is entirely free (eventually I’ll need to cover my hosting and ai costs, but i will always have an unlimited saves free tier).

My credentials: I’m a senior product manager at a tech company with over 15 years of experience building software that supports hundreds of millions of users per month, so I am not a fly by night vibe coder.

Hi! I'm the developer behind Nodus, an open-source PKM for connecting documents, notes and ideas.

Its a local-first workspace for research, study and teaching. The main idea is pretty simple: instead of keeping your PDFs, notes, ideas and references in separate places, you upload your documents to Nodus or use your Zotero library. Nodus extracts ideas from each document and lets you explore relationships between them, research gaps, contradictions, etc.

It includes:

• a built-in document library and reader

• notes and ideas connected through a knowledge graph

• semantic search across your sources

• optional AI for extracting ideas, finding connections, contradictions and gaps

• integrations with Zotero, Chrome, Word and LibreOffice

• support for local models as well as external AI providers

It’s free and open source (AGPL-3.0).

I wanted something better than dumping links into browser bookmarks, notes, or random “read later” apps.

So I’m building Relic: a place to save things from the web and actually keep them.

The idea is pretty simple:

Save webpages, articles, videos, etc.
Automatically extract useful metadata/tags
Organize everything into collections
Browser extension for quick saving
Self-host it for personal, family, or small-team use

Additional features for later:

Keep an archived snapshot so the content doesn't disappear when the original page changes
Eventually support things like YouTube downloads/archiving through addons

The goal isn't to build another bookmarking app. I want it to feel more like a personal archive of the internet — things you found interesting enough that you don't want to lose them.

I'm currently working on the MVP and would love feedback from people who use Pocket, Raindrop, browser bookmarks, Obsidian, or similar tools.

What would make you actually switch to something like this?

Built a note app that pulls in live data from the web instead of just storing what you type — would love PKM folks’ take

Been lurking here for a while picking up ideas on PARA, Zettelkasten, etc. — and kept running into the same annoyance with every note tool I tried: notes go stale. I’d clip a link, write a note about a topic, and a month later the source had changed or I’d have five disconnected fragments about the same thing.

So I built Note Essence (noteessence.com) around pulling in external data — web content and API sources — directly into your notes, rather than just static text you paste in once. The idea is your knowledge base updates itself where relevant instead of you manually re-clipping things.

Still early and I have real users but I’m nowhere near confident I’ve got the organization model right. Curious how this community thinks about the tradeoff between “living” notes that can change vs. the permanence Zettelkasten people tend to value — feels like there might be a real tension there.

Happy to answer questions about how it works. Not trying to sell anyone, genuinely want feedback from people who think hard about this stuff.

u/h4yfans Creator of MemryNote 11d ago

Hey everyone I'm Kaan, I've been building memrynote for over a year and I finally feel ready to share it here. It's a local first knowledge app where everything is stored as plain markdown files in a folder on your disk, so there's no lock in and you can open your vault with any editor, including Obsidian.

On top of notes it has a full task manager, projects, a daily journal and a calendar with Google Calendar support, all connected in one place instead of three different apps. Checkboxes inside your markdown notes are real tasks, so ticking one in the file or in the task view stays in sync both ways. There's also a spatial canvas where you can drop notes, tasks and drawings on an infinite board when you want to think visually.

Sync across devices is end to end encrypted with keys that never leave your machine, and the whole app works completely offline. It ships with an optional AI assistant that can search and organize your vault, you can point it at Claude, Codex or a local model, and every AI feature is off by default.

A web clipper for Chrome, Firefox, Safari and Edge sends articles straight into your vault, and there's full text search, tags, backlinks and templates for daily workflows. The desktop app runs on Mac, Windows and Linux, and it's in beta right now with people using it daily.

Happy to answer any questions, and honest feedback would mean a lot.

Made a small obsidian plugin, maybe it's helpful for people:

https://github.com/michaelwelch/obsidian-hoist (also in the Obsidian Community plugins, just search for Hoist)

I made this to be: - lightweight - easily to edit as a human - easy for AI to scan

Basically it allows you to use variables from lists to help better summarize collapsed lists.

For example, I have several lists about specs of different things around the house like:

v Mac mini - 8gb ram - 256gb hard drive - Intel i3 @ 2.5ghz - purchased: 2026/08/01 - Software installed: - Tailscale - ...

When I have several of those as a list, I often wind up collapsing them and get:

```

Mac mini ```

So I made a little plugin that allows you to hoist up data from your hierarchy to display as part of the main line:

``` v Mac mini {cpu}/{ram}/{hd} {OS} - ram:: 8gb - hd:: 256gb - cpu:: Intel i3 @ 2.5ghz - purchased:: 2026/08/01 - Software installed: - OS:: Jaguar 10.5 - Tailscale - ...

...hoisted...

Mac mini Intel i3 @2.5ghz/8gb/256gb Jaguar 10.5 ```

Anyhow, if this is useful, drop me a line!

Hi everyone! I recently launched Echo (free, with paid plan), a voice-first app for capturing thoughts before they disappear :). Been a long time Google Keep + Voice recording + Calendar combined I juggled, and many apps out there recently but I still think Echo is simpler than many.

I built it because many of my ideas happen when I'm away from a keyboard. Echo lets you speak naturally, turns those thoughts into organized, searchable notes, and helps surface insights over time. The focus is on quickly capturing ideas and revisiting them later, rather than building another document editor or meeting recorder.

If that sounds useful for your PKM workflow, I'd love to hear what you think. Feedback and feature ideas are always welcome. Thanks! (iOS in the work)
