List your weekly tasks, pick the ones AI can draft, and see how many hours come back and how many turn into checking AI's work.

This is an estimate built only from your own inputs. Replace the example tasks with yours, and be honest about how long checking takes: facts and numbers need more than a skim.
Example data. The starting tasks, hours and checking times are guesses for an example office week, not measurements.
