Mnemosyne OS

For Notion people

Keep Notion for building.
Take a memory that you own.

Notion is great for building. But your knowledge lives there in someone else's cloud. Export it to markdown — native in Notion — and Mnemosyne turns it into a local, encrypted memory you can query by meaning. Yours. Offline.

One step, honest

Notion exports to markdown. Mnemosyne takes it from there.

In Notion: Export → Markdown & CSV. You get a folder of .md files on your disk. You point Mnemosyne at it, and it vectorizes them locally.

Let's be clear: this isn't magic real-time sync via the Notion API. It's an export you redo whenever you want to freeze the state of your knowledge. Simple, and no surprises.

What you gain

Knowledge you own, and that answers back.

The day Notion raises its prices, changes its terms, or pushes an AI you don't control — your knowledge is already on your machine, in the clear, readable without a subscription. It's insurance, not a migration.

And on your disk it becomes queryable by meaning, not just by keywords — and it feeds the AI that you plug in, locally or with your key. What you've accumulated finally starts working for you, without leaving your machine.

You wrote it all in Notion. Take back its memory.
