JOIN THE HUB:first, see why — The Linux WindowFAQs
We have questions too
Is it really free?
Yes. The whole app is free for everyone, under the GNU GPL v3 or later. No trial, no ads, no account.
So how is it sustainable?
[Answer from the Business thread — N22.] Our direction: whatever costs money to run — sync, certified timestamps, support for schools — is paid for by those who need it. Supporters keep the lights on, and an open ledger shows the numbers.
What does it run on?
Debian 13 (trixie) on amd64, as a .deb package. A Flatpak is planned; other distributions follow your votes.
Do I need the internet or an account?
No account, ever. Your notes stay on your computer. The internet is used only when you say yes — to download a speech model, for example.
Whose AI is it?
Yours. Speech recognition, read-aloud and the local AI run on your own machine by default. If you prefer, you can plug in your own Anthropic API key.
Can I bring my OneNote notebooks?
Yes. OneNote .one files import one way, without loss. Nothing is ever written back to them.
Is there a phone app?
Compendium Companion for Android reads your notebooks and takes dictation offline. It has no internet permission at all — and anyone can check.
Is it really gluten-free?
Yes. Side effects may include finished homework and a headache of Olympian proportions. Zeus had it worse — that’s how Athene was born.
MIRA: THE IMAGINED STUDENT WE BUILT IT FOR. FICTIONAL STUDENT, REAL LIFE FEATURES.
“I study physics in Paris, my lab is in Berlin and my grandmother lives in Budapest — so my notes live on trains and airplanes. I record the seminar, and by Budapest the transcript has told the voices apart. I say an equation out loud and it comes back as math; I sketch the circuit right next to it. No account, no signal, nothing to pay. When my eyes are tired, it reads my notes back to me aloud. It can summarize it all if I need, it’s the first notebook that thinks the way I do.”
Mira, 24 · Physics MSc · Paris ⇄ Berlin ⇄ Budapest
