Trevor AI is an AI-powered daily planner that uses time blocking to schedule tasks directly into your calendar. It estimates task duration, suggests when to do each task, and stays in real-time sync with Google or Microsoft Calendar.

Our take
Trevor does one thing: turning a task list into a scheduled day by placing tasks into real calendar time. That constraint is the point, and people who struggle with time estimation rather than task capture get the most from it. It will not fix an over-committed calendar; it will make the over-commitment visible, which is genuinely useful and slightly uncomfortable.
Worth it if
People whose problem is planning when work happens rather than remembering what to do.
Look elsewhere if
Team project management — this is a personal planning tool, not a coordination system.

A to-do list holds an unbounded number of items; a calendar holds a finite number of hours. Time-blocking forces the two together, which surfaces the fact that a twelve-item day does not fit. That confrontation is the actual mechanism, and it is why people either find this approach transformative or abandon it in a week.
Does it handle a day that goes off plan?
Rescheduling is supported, and the harder part is behavioural rather than technical. Time-blocking systems fall apart when a plan breaks and the user stops trusting the schedule. The practical habit is to re-plan the remaining hours rather than abandoning the day, which most people need to learn deliberately.
