Diarized
Time blocking around a calendar that is mostly meetings
Six hours of meetings and a to-do list written by somebody who believed there would be time between them.
What Diarized does about it
Diarized only ever writes into genuinely free time and never touches an event it did not create, so your one-to-ones and your team's holds stay exactly where they are.
Reads the app you already use
Microsoft To Do
Asana
ClickUp
Those are the ones people in this situation tend to keep. Diarized reads 11 task apps in total, and your tasks stay in whichever one you already use.
What it will not do for you
It will not move your meetings, decline anything, or defend your calendar. If the meetings leave no room, it will honestly leave the work unscheduled rather than pretend.
Everything else that was looked at and refused, with reasons.
