Auto-scheduling
Auto-scheduling is letting software place your tasks in your calendar for you, around the meetings already there, and move them when things change. You supply the work, its priority and its deadline; the tool decides when each piece happens.
Also called: automatic scheduling, AI scheduling
Where it goes wrong
The interesting question is never whether a tool auto-schedules, because they all do. It is what happens when two tasks want the same slot, and whether the tool will tell you why it chose. A scheduler that cannot explain a placement is asking for trust it has not earned.
Diarized schedules the work you already keep in a to-do app into the calendar you already use, and shows you why every block landed where it did.
