Help center
Learn the main workflows, troubleshoot common problems, and contact support.
Organize your tasks
Capture new tasks in Unsorted, then use Today, Week, Starred, All, and Completed to focus the list. Open any task to add notes, subtasks, due dates, reminders, comments, assignments, or attachments.
Work with shared lists
Open a list’s actions to invite collaborators, review members, rename the list, change its background, archive it, or delete it. Shared-list permissions determine which actions are available.
Use Thunderlist offline
Thunderlist keeps recent workspace data available for offline use and queues supported edits until a connection returns. Leave the app open briefly after reconnecting so pending changes can sync.
Troubleshoot a problem
If something is not working, note the route, device or browser, action you attempted, and what happened. Send those details to support@bayonai.com; never include a password or verification code.
