Mnemosyne OS

For people who write in markdown

Your notes are files.
Give them a memory.

Obsidian, Logseq, Zettlr, Foam, or a plain folder of .md — if your notes are markdown files, Mnemosyne reads them. Right where they live, they become a memory you query by meaning, across years of writing, and 100% local. It doesn't replace your editor; it plugs into it.

We speak the same language

Local-first, plain files, zero lock-in.

That's your DNA. It's ours too. Your notes are markdown files on your disk — Mnemosyne reads them right where they are, no account, no server, no mandatory cloud. You can unplug everything tomorrow: your files haven't moved a single byte.

No proprietary lock, no export to negotiate. The same standard that made you pick files over a closed database.

What changes

From "where did I already write this?" to "just ask".

Keyword search finds what you already remember. Retrieval by meaning finds what you forgot you wrote — the note from two years ago that answers today's question, even without the right word.

And this memory doesn't sit in a corner: it feeds the AI you plug in — yours, local, or via your own key. Your assistant stops starting from scratch. It works from what you've already thought.

You already write everything down, in plain text. Only the memory was missing.
