Hearth

A warm AI companion that lives entirely on your phone. Private, offline, yours.

Coming sooncom.offlineai.companion

Characters with their own persona and memory, who talk to you on your own phone. The conversation is not training data and not a support ticket — there is no server holding it.

Portraits are generated on-device too, so a character gets a face without a single image leaving the phone.

What it does

Characters with persistent memory and their own voice
On-device portrait rendering
Conversations excluded from cloud backup by default
No subscription, no per-message cost

The wedge

A companion whose memory of you is on your device only.
