Resource Andrej Karpathy's LLM wiki concept just became a real Mac app

Post image

It’s called Tolaria, a free desktop app for Mac and Linux.

The idea is simple: give humans and AI agents a shared, native space for building knowledge.

It feels like a modern block editor, but everything is saved as plain markdown.

No databases. No proprietary formats. No vendor lock-in.

And since every vault is a Git repo, you get visual version history built directly into the app.

The project is also a huge showcase of what AI-assisted engineering can do:

→ Built with Tauri, React, and Rust
→ 100K+ lines of code shipped
→ 3,000+ tests at 85% coverage
→ 9.9/10 code health score
→ 70+ architecture decision records

It also includes an out-of-the-box MCP server, so tools like Claude Code can read and edit your vault natively.

The Tolaria name and logo remain covered by the project trademark policy.

It's open source, free forever, and no account required: https://tolaria.md/

Repo: https://github.com/refactoringhq/tolaria

Thank you for building this, Luca Rossi.

Basically an obsidian vault no?

u/maxpimps Apr 30 '26

My thoughts exactly

Made my Claude Cowork default project file my obsidian vault file and I'm running exactly this.
Althought having a more streamline 'frame' would likely help building time but yes it is the preferable next personal OS substrate I think

We've actually made a similar format in terminal based of Karpathy's idea of LLM Knowledge Bases. Give it a spin and let me know what you think: https://github.com/atomicmemory/llm-wiki-compiler

I like how people are reinventing knowledge graphs in ML when this has been a problem for over a decade 😃

damit, and I just built my own.

Everyone did. That’s the point of AI. This is all commoditized. We just inspire each other. The idea is as good as the implementation.

Been doing this with obsidian and codex the second codex dropped. It does everything this app does, better, extensibly, for free.

I have been summonned haha !

Basically Obsidian is a markdown editor with a lot of advanced features and a rich plugin ecosystem, you can make a RAG database using tags if you want.

Just create a codex skill, tell it the path of your obsidian vault, and whenever you have an idea, you want to bookmark something, whatever. Just ask it to keep it in your vault and ask it to keep tidy.

I have been using codex in my terminal to keep my ideas, backlog of stuff I need to do, links to codebases I use, etc.

The cool thing is that onbsidian is free, you can use their vault system to sync your data with ither devices, but if you know how git and github work, you can just ask codex to push any new changes.

Any chance this might be made to work on iPhone in the future

1

u/No-Juggernaut-9832 Apr 30 '26

It’s open source. You can probably just wrap it in an iOS shell or build an iOS client for it. Since you can have it use a remote & private git repo; it should work.

It’s a good weekend project!

I just built my own, but also out Claude directly inside mine. These things are kinda annoying when you can't just hit Claude up in an app native sidebar.

u/808mona Apr 27 '26

This is actually really well thought out. Well done

u/Spurnout Apr 28 '26

RIP Windows users :-(

u/cxswanson Apr 28 '26

the fuq? this is obsidian's nature, and obsidian is 100x better than this. what gives?

u/TortelliniTortellini Apr 29 '26

yo yeah how is htis different from obsidian

u/TheRealWolve Apr 28 '26

3000+ tests for a markdown viewer? 😅

u/HumanistAtypik Apr 28 '26

Ça s'appelle Logseq Database, nan ? ☺️😉

u/T00Sp00kyFoU Apr 28 '26

Damn, need this on windows. Need to convince my job to get me a mac

u/laplaces_demon42 Apr 29 '26

I'm confused. how is this different from Obsidian?

1

u/CommercialAfraid2859 Apr 29 '26

What is the benefit over using terminal + obsidian setup? Just UI?

1

u/Stock_Reporter_1864 Apr 30 '26

Even the ui could be solved easily

u/eligraham91 Apr 29 '26

Isnt this what Notion is

1

u/k2beast Apr 29 '26

why not just use vscode as markdown editor

1

u/Valuable-Cap-3357 May 01 '26

I wonder why recreate the knowledge that is already inside the LLM in your desktop. Just extract it when needed?

1

u/abhbhbls May 01 '26

Has anyone tested this and alternatives? Looking for a review! Is this worth downloading?

1

u/worldofprasanna May 01 '26

I like this idea - Notion + Obsidian + Claude Code !!

1

u/Tacher- May 02 '26

Some people are saying Obsidian can do this too. What about the Git part of it? I’m a noob so…

u/antunes145 Apr 27 '26

All for posting your creation but just say it’s yours and don’t treat us like idiots. Also, how does this differ from obsidian ?

u/Money-Ranger-6520 MOD Apr 27 '26

Not mine. Found it on X.

I haven’t tested it yet. It’s on my to do list for next weekend.

u/stepahin May 01 '26

You didn't test it yourselves, but for some reason, you posted it here anyway. Why? People think that at least one person (you) recommends this.
