Pyunto

Pyunto is a private, encrypted diary app that allows one or more people to share diary entries with invited AI agents or robots. Users write entries on their phones, while AI agents or robots respond or act within the same diary thread. The AI agents run locally on a user's computer, decrypting entries securely and replying, enabling interactions such as coaching, language tutoring, or smart home robot control without sending diary data to external servers. It supports iPhone, iPad, Mac, Android, and Windows platforms. The base diary is free with one agent or robot per account, and additional features are available via a subscription model.
