How we picked these ai chief of staff
Every tool chosen for this list needed to have a clear free path, either as a no-cost tier or a meaningful free trial, and enough feature depth to act as a true chief of staff rather than a simple chatbot. We weighed how much context each assistant builds automatically, how easy it is to reach across email, calendar, text, and phone, and how cleanly the pricing scales when you need more capability. Each pick also had to be reliable enough for real day-to-day use, with clear plans and no hidden setup requirements.
