How does an AI planner work with my existing calendar?

AI planners connect to your calendar through secure integrations, read your existing events, and schedule new tasks around them automatically. After you grant access, the AI identifies your meetings, busy blocks, and free windows, then places your goals and tasks into realistic open slots. When something changes, like a meeting running long, the AI reshuffles affected tasks instead of leaving you with an impossible list. Orby follows this model closely: you dump your goals, it syncs with your calendar on iPhone, iPad, or Android, and it rebuilds your week whenever reality shifts, sending warm reminders rather than alarms. Motion uses the same core idea tuned for workplace deadlines, while Sunsama layers manual review on top of calendar data. Basic apps like Todoist or Structured display calendars but lack true automatic placement. Most AI planners, including Orby, offer trials so you can test the integration first.
