About MyBrain
MyBrain is an open-source productivity app for Android that combines tasks, notes, calendar, diary entries, bookmarks, and an AI assistant in one place. The project is hosted on GitHub under a GPL-3.0 license and is currently targeting Android.
With the app, you can create tasks with priorities, sub-tasks, due dates, and reminders, and write notes with Markdown support for headers, lists, and links. You can record daily mood entries and view a mood summary, save bookmarks through the share menu from other apps, and view calendar events in list and monthly views with a home screen widget. A dashboard shows tasks and calendar events for the day. The AI assistant can chat, work with attached items, and create or find items on request. Data stays local with no data collection, and encrypted sync is available between devices on the same local network.
It suits Android users who want a single private, local-first app for daily planning, notes, and journaling instead of using separate apps.
