Injourn

Injourn is a private digital journal application that turns daily entries into monthly narrative summaries.

Injourn is a private AI journal, diary, and mood tracker designed for daily reflection. Users write a few lines a day detailing their mood, feelings, and activities. At the end of the month, the application uses Google Gemini to write the month back to the user in narrative prose based only on their entries. The platform prioritizes privacy by keeping entries AES-256 encrypted on the device with no public feed or required account. Users can back up their data to their own Google Drive. Additional features include dynamic themes that shift with the time of day, stationery styles, and insights tracking mood patterns and drivers.
