Show HN: Tolaria – open-source macOS app to manage Markdown knowledge bases(github.com)
Hey there! I am Luca, I write https://refactoring.fm/ and I built Tolaria for myself to manage my own knowledge base (10K notes, 300+ articles written in over 6 years of newslettering) and work well with AI.

Tolaria is offline-first, file-based, has first-class support for git, and has strong opinions about how you should organize notes (types, relationships, etc).

Let me know your thoughts!

I run a newsletter too, so this is cool to see! Not sure if I need it yet (my "knowledge base" is still pretty small), but I'll definitely keep it in mind for the future.

Doesn’t Obsidian already do pretty much the same?

Obsidian and these newer tools share markdown + local files, but they're aimed at different assumptions about who reads and edits the vault. Obsidian's default is "human reads and curates; plugins optionally enhance." The AI-first cohort (Tolaria, Sig in the sibling comment, and several others) assumes the AI reads and writes as a first-class agent, which makes design choices like how the app reacts to files changing underneath it (cf. the Zettlr comment downthread) a core concern rather than an edge case.

Worth watching how each of these tools positions the AI: as a UX copilot inside the editor, or as an autonomous agent with file-system access via local CLI/MCP.

It would be nice if you could “see” the AI in your vault making changes. Almost like a Google doc collab session. Even if you weren’t directly interacting with the agent, and it was making change thru a CLI/MCP, its presence would be highlighted in the frontend. And then it appears as its own contributor in the git history.

And I was going to say Mac native as well, but uses Tauri. I’d love some app with the polish of Bear Notes but that just edited raw Markdown files. Ideally Obsidian with the Notebook Navigator plugin (strongly inspired by Bear Notes perhaps?) and (checks list) this very specific list of plugins that I need and should be good for everyone else thanks.

Huh, somehow I had no idea that Obsidian wasn't open source. I guess I was fooled by the open source plugins.

Zettlr would like a word.

I really like Zettlr, but I find it is always crashing when markdown changes behind the scenes and it has the document open.

It's so good for viewing all markdown in a repo, but dies all too often.

Yes, but the claim is presumably that this one is good.

Wow thanks!

Better than the one I was planning to build for myself.

Love the UI. Love the fact that the app was made with Tauri.

Nice work, will share!

A freaking web app?

Boo. Boooooooooo. Thanks but no thanks.

At least it's Tauri!

Just another disposable piece of software maintained by a single person that does 80% of what other apps do but worse.

Please cut this out. You really don't want to live in a world where individuals are discouraged from trying to build things that are good.

If you want something to stick around: you have to use and pay for it.

But if they ever choose to decommission it, they have the chance to do the funniest thing:

You're right. We should absolutely only rely on "Ask sales for price" closed-source software from megacorps, that get worse on every release, and get sunset anyway when the funding runs out.
