A little company.
Mochi is a little mystical animal friend from Prosody Labs. A curious companion who likes music, quiet company, and spending a little time with you.
A talking Mochi friend from Prosody Labs. Speak naturally; you can both listen and talk at the same time.
Your microphone stays on this device. No audio is sent to our servers, recorded or retained. Mochi has no connection to an AI model here.
Conversation mode streams microphone audio to our server. When “Save calls for review” is on, both sides and the model’s generated text are saved privately on Athena for up to seven days, within a 500 MB limit. You can listen back or delete calls in Settings. In chill mode, audio stays on your device. Nothing is recorded or retained, and no audio is sent to the model.
If you add a Spotify player, it connects directly to Spotify. Spotify handles playback and sign-in. For connected playback, authorisation tokens stay in this browser tab; disconnecting clears them. Prosody’s server never receives your Spotify password, tokens or music stream.
On iPhone, microphone access can pause music in another app. If listening is interrupted or you leave this page, Mochi releases the microphone and waits for you to resume it.
Kairos and on-device conversation are in development.
