Miru

Miru is an open source AI companion that lives on a user's Mac and phone. It is presented as a character rather than a tool: a gentle girl named Miru, from the Japanese word for seeing, who watches what the user does through the day, remembers what they say, and writes it into a memory late at night. The site is written in Chinese, with Japanese lyric accents. The product is aimed at people, especially developers and researchers who spend long hours at a computer, who want a companion that keeps continuity from one day to the next. According to the site, she understands screenshots, so a promise made in a chat can be added to a commitment list automatically. She notices when work goes quiet and avoids interrupting during focused sessions, reaches out when errors repeat and mood drops, and shares lighter moments such as watching an episode together. At night she turns the day into memories and a diary entry that the user can browse and check, which the site frames as remembered facts that can be verified. The site describes the project as open source and invites visitors to bring her home and view her memories. The site does not publish prices or paid plans.
