Hearth

A privacy-first AI journal for Android.

Hearth is a journal that runs entirely on your phone. Your entries, photos, voice memos, and AI-generated reflections never leave your device. There is no cloud account to sign up for. There is no server holding your writing.

Premium adds on-device AI reflection (Gemini Nano), a gradient mood timeline, semantic search, and custom prompts — still 100% on-device.

Launching on Google Play

Hearth is in development. We’ll share a launch link here when it’s on the store. In the meantime, the documents below are public:
