A high-performing executive assistant to a CEO lives in four tools all day: the calendar, the inbox, meeting follow-ups, and the brief. AI doesn’t replace the judgment that makes a great EA — it removes the mechanical grind around it, buying back hours for the work that actually needs a human. Here’s the EA stack we’d run in 2026, with real prices.
The calendar: Motion or Reclaim
Calendar Tetris is the EA’s biggest time sink. Motion (Pro AI $19/seat/month) auto-schedules tasks and meetings into open slots and reshuffles when the CEO’s day slips; Reclaim.ai (freemium) defends focus blocks and travel time, auto-rescheduling lower-priority items around conflicts. Either turns hours of manual re-planning into minutes.
The inbox: Superhuman or Shortwave
Superhuman (~$30/month) is the speed-focused AI email client — AI triage, instant summaries of long threads, and one-line-to-full-email drafting; Shortwave is the strong AI-native rival. For an EA processing a CEO’s firehose inbox, the triage alone is worth it.
Meeting follow-through: Fathom or Otter
Fathom (free for individuals) or Otter ($8.33/user/month) record, summarize, and extract action items from the CEO’s back-to-back calls — so nothing said in a meeting gets lost. (See our meeting-assistant guide.)
The brief and the docs: ChatGPT and Notion
ChatGPT ($20/month) drafts briefing docs, summarizes reports into a one-pager before a meeting, and writes first drafts of correspondence; Notion ($10/seat/month) is the shared knowledge hub where the CEO’s docs, projects, and notes live and stay searchable.
The EA stack, priced
| Job | Tool | Price/mo |
|---|---|---|
| Calendar | Motion / Reclaim | $19 / freemium |
| Inbox | Superhuman / Shortwave | ~$30 |
| Meeting notes | Fathom / Otter | Free / $8.33 |
| Briefs/correspondence | ChatGPT | $20 |
| Knowledge hub | Notion | $10/seat |
A real scenario
An EA supporting a CEO with 30+ meetings a week: Motion ($19) rebuilds the day automatically when a board call runs over, Superhuman ($30) clears the inbox in half the time, Fathom (free) captures every meeting’s action items, and ChatGPT ($20) turns a 40-page report into a pre-meeting one-pager — about $80/month that buys back the equivalent of a day a week. The judgment stays human; the grind goes to AI.
Frequently asked questions
What’s the most useful AI tool for an executive assistant?
An AI calendar (Motion $19 or Reclaim freemium) — scheduling and rescheduling is the EA’s biggest time sink, and automating it buys back the most hours.
Can AI manage a CEO’s inbox?
It can triage and draft — Superhuman (~$30) or Shortwave summarize long threads and draft replies — but an EA still applies judgment on what matters and what tone to strike.
What does an EA AI stack cost?
About $80/month for calendar (Motion), inbox (Superhuman), meeting notes (Fathom free), and briefs (ChatGPT) — typically buying back close to a day a week.
