Google Tasks is Google's lightweight task manager — integrated directly into Gmail, Google Calendar, and Google Workspace — letting users turn emails into tasks with a single click and view them alongside calendar events. Simple by design, it offers subtasks, due dates, and repeat options without the complexity of dedicated task apps. For users already living in Gmail and Google Calendar, Tasks provides just enough structure to capture and track work without the cognitive overhead of switching to a separate tool.
