Frequently asked questions
Is my recording uploaded?
Raw audio and local projects stay in your browser. When you use Jev, structured note data and your configured API key are sent to TypeSafe through this site's server.
How are local AI continuation and Jev note choice different?
Local AI generates a short continuation; Jev selects one next note from candidates, and the browser handles playback.
