What's the difference between an AI chief of staff and an AI executive assistant?
The EA owns the mechanics — calendar, inbox, travel, expenses. The Chief of Staff owns the judgment — meeting prep, follow-up ownership, decisions log, leadership sync facilitation. EAs execute; CoS translates priorities into workstreams. Most founders end up with both, and the AI versions compose well — the EA handles the logistics, the CoS handles the substance, and they pass tasks between each other fluently. Think of it as the difference between 'schedule the meeting' and 'why are we meeting in the first place'.
