What is it?
Mindwtr is a to-do app built around the Getting Things Done (GTD) method. It walks you through capturing tasks and ideas into an Inbox, breaking projects into next actions, tracking items you are waiting on, keeping Someday/Maybe ideas, and running a guided weekly review. The app works offline and does not require an account.
It runs on Windows, macOS, Linux, iOS, iPad and Android, and data stays on your device by default. Sync is optional and can use iCloud, Dropbox, a shared folder, WebDAV, or a self-hosted server. Tasks can also be imported from Todoist, TickTick and OmniFocus.
The project also offers a local API and an MCP server for connecting other tools, and AI assistance is off by default and can be enabled by the user.
