What an AI chief of staff does
- Triages your inbox.Sorts mail into what needs you, what is drafted and waiting, and what is filed.
- Drafts replies in your voice.Learns from your sent mail so drafts sound like you, and waits for your approval.
- Tracks commitments.Notices promises such as "I'll send it Friday" in email and meetings, and follows up when they slip.
- Prepares and captures meetings.Briefs you before each call, then records decisions and action items.

Why executives need one
The load is measurable. Microsoft's research on the "infinite workday" counted it, and Gloria Mark's research at UC Irvine measured what each interruption costs.
Sources: Microsoft WorkLab, "Breaking down the infinite workday", 17 June 2025; Gloria Mark, University of California, Irvine, field study reported in 2006 (time to resume a task; her peer-reviewed 2005 figure is 25 minutes). The same report counts 153 Teams messages per weekday on top of the email.
An AI chief of staff absorbs that load. It sorts the mail, writes the reply before you ask, captures the unplanned call and remembers what was promised, so your attention goes to decisions.

Frequently asked questions
Is an AI chief of staff the same as an AI executive assistant?
The terms overlap. "Executive assistant" usually means inbox and calendar help. "Chief of staff" adds follow-through: tracking commitments, preparing for meetings and keeping work moving.
How much does an AI chief of staff cost?
Single-purpose email assistants commonly start between $20 and $50 a month and stop at the inbox. A chief of staff that also runs your meetings and tracks every commitment starts at $99 a month with Senapra, about one percent of what a human chief of staff earns. See our sourced price comparison.
Will an AI chief of staff replace my assistant?
For many founders it covers the routine work. Teams with an assistant often use it to give that person more time for higher-value work.
Is it safe to connect my inbox?
Look for encryption in transit and at rest, a Data Processing Agreement, approval before any send, and a way to delete all your data. Here is how Senapra handles each.
