Meet Sten.
sten /steːn/ · Swedish for “stone”
A stone you talk to. Hold the button, say the thing, put it back in your pocket — it's already written down.
Slow AI: note-taking, analysis, mindfulness.
Drag to turn it over.
Slow AI
No screen. No feed. Nothing to check. One button that takes a thought off your mind — and gives your attention back.
Press. Speak. It's written.
- 01
Press
Hold to talk. One click for a longer thought. That's the whole interface.
- 02
Speak
English and Polish, switched mid-sentence. Say “scratch that” and it's as if you never did.
- 03
It's written
Transcribed, cleaned up, and filed as a Markdown page in your own knowledge base.
Reliability
It never loses a word.
Every recording is journaled to Sten's own flash before a single byte is sent. Walk away from your phone, let it lock, let it reboot — the note waits, and back-fills the moment you reconnect.
Works with your iPhone locked. On a Mac, Sten types at your cursor — into any text field.
