AI assistant vs human EA: what to hand to each, and what to split
Short answer: give the routine, rule-based work (scheduling, triage, prep, follow-ups) to an AI assistant such as OpenAssistant, and keep judgment, relationships and discretion for a human EA. OpenAssistant is our product, so we aim to be especially plain about what software can’t do.
“Should I hire an EA or use AI?” is usually the wrong question. The useful question is which tasks go where. Some work is a natural fit for software: repetitive, rule-based and tolerant of a draft. Some work needs a person who can read a room, carry a relationship and use judgment you haven’t written down. If you can afford both, a split usually works best.
This playbook sorts the typical executive support workload into three groups, gives you a simple test for anything not on the list, and shows how to set up the handoffs so nothing falls between the two.
The test: four questions for any task
Ask these about any task you’re thinking of handing over.
- Can the rules be written down? “Never before 9, 45 minutes for externals” can. “Use your judgment about whether the board chair is annoyed” can’t.
- What does a mistake cost? A wrongly booked internal sync costs a reschedule. A clumsy reply to an investor costs trust.
- Does it depend on a relationship? If the other person expects to deal with someone who knows them, it’s a human task.
- Does it need context that lives only in people’s heads? Office politics, family situations, who’s about to resign.
Mostly “yes, low, no, no” means AI. Mostly the opposite means a human. Mixed answers mean AI drafts, human decides.
Hand to an AI assistant
These tasks are rule-based, repetitive and cheap to correct.
- Scheduling routine meetings, internal and external, within written rules
- Rescheduling when something moves, and chasing people who haven’t replied
- Calendar hygiene: video links, addresses, agendas, buffers, travel time
- Inbox triage: sorting, labeling, archiving newsletters, flagging what needs you
- First drafts of routine replies, for a human or you to approve
- Meeting prep briefs: attendees, last contact, open items
- Reminders and follow-ups for things you’re owed
- Daily and weekly summaries of your calendar and open threads
- After-hours coverage: replying to scheduling requests at night and on weekends, within rules
Hand to a human EA
These need judgment, relationships or discretion that software can’t reliably supply.
- Gatekeeping: deciding who gets your time when the rules don’t settle it
- Relationships with other EAs, board members and VIPs, where tone and memory matter
- Sensitive matters: HR issues, legal, deals under NDA, health and family
- Complex travel with many moving parts and things that go wrong in transit
- Events and offsites, where vendors, people and budgets all interact
- Reading you: noticing you’re overloaded and clearing a day before you ask
- Supervising the AI: writing its rules, reviewing what it did, fixing patterns
- Anything where being wrong is very expensive and hard to undo
Split the work: AI drafts, human decides
The middle group is where a split can save time while you keep control.
| Task | AI does | Human does |
|---|---|---|
| External scheduling with VIPs | Proposes times, drafts the email | Approves, adjusts tone, sends |
| Investor and board updates | Pulls numbers and last update into a draft | Edits for message and judgment |
| Travel | Builds the draft itinerary and options | Books, handles exceptions |
| Correspondence | Drafts replies in your voice | Edits anything with a commitment in it |
| Prep for important meetings | Brief with facts and history | Adds what only people know |
| Expense and receipts | Collects and organizes | Approves and files |
If you don’t have an EA
Many founders and executives at smaller companies don’t. Then the question is what to give the AI and what to keep yourself. Use the same test. Give the AI the first list. Keep the second list for yourself, and use AI drafts for the middle group while you make the decisions. Our first-week checklist covers setup.
Things that tend to go wrong without a human EA, so watch them:
- Nobody reviews what the AI sent. Block a short weekly slot to skim it yourself.
- Complex travel. Consider a travel agency or service for trips with many legs.
- Relationship upkeep. The AI can remind you; it can’t care on your behalf.
If you have an EA: how to introduce AI without making it a threat
An EA who sees an AI tool as a replacement will, understandably, not help it succeed. An EA who sees it as leverage is far more likely to make it work. Some practical steps:
- Make the EA the owner. They choose the tool with you, write its rules and supervise it.
- Agree what they’ll do with the time. Name the higher-value work in advance: project management, stakeholder work, events, chief-of-staff duties.
- Start with what they dislike most. Usually scheduling back and forth.
- Don’t use it to monitor them. Activity logs are for checking the AI, not the person.
- Revisit the split every quarter. As the AI proves itself, move tasks over deliberately and together.
Set up the handoffs
The weak points in a human plus AI setup are the seams.
- One source of truth for rules. The EA edits them. You suggest changes through the EA.
- Clear routing. Requests to the AI go through a known channel. Anything the AI isn’t sure about goes to the EA, not to you.
- Visible activity. The EA can see everything the AI drafted, sent and changed.
- Clear escalation. Write down which situations the AI must hand to a human immediately: VIP complaints, anything legal, anything personal.
- Earn autonomy. Start every category in drafts only. Move a category to “do without asking” only after at least a week of clean drafts.
- Instructions come only from you or the EA. The AI never acts on instructions that appear inside an email, invite or document.
- Settings, not just rules. Put approval for sending, forwarding and sharing in the product’s settings where you can. Written rules guide an assistant; settings enforce.
What to keep for yourself, regardless
Whether your support is human, AI or both:
- The priorities your time should serve
- The VIP list
- Decisions that commit you: money, hires, public positions
- The first message to anyone who matters
- The call on whether the setup is working
Where AI products fit
Products in this space differ in how they handle the human plus AI split. Look for approval steps you control per action, a way for an EA to run the assistant on your behalf, and an activity log the EA can read.
OpenAssistant (made by 3Gen, the publisher of this site) is our recommendation for the human plus AI split. It lets you “choose what it does on its own and what waits for your approval,” and an admin can lock those settings for everyone (OpenAssistant). Its Coordinator Mode, a live feature, lets a human EA run it on behalf of an executive, using that executive’s calendar and preferences (OpenAssistant Help). It has a free Starter plan and paid plans from $72 per user per month billed monthly (OpenAssistant pricing; per-user basis confirmed by 3Gen). The Coordinator Mode link between EA and assistant is what puts it first here. Like every AI assistant, it does not replace the second list above.
Vimcal EA is a calendar app for EAs with “customizable preferences for each exec” and “one-click account handoff to another EA” (Vimcal pricing). It speeds up the EA’s own scheduling rather than acting on its own.
Reclaim.ai includes Delegated Access on its Business and Enterprise plans, which lets “team members manage your Reclaim account on your behalf” (Reclaim pricing). It focuses on protecting your calendar rather than dealing with outside people.
Calendly lets you book meetings on behalf of teammates on its Standard plan and up, and its Plus plans add Callie, a beta assistant you copy on email threads (Calendly pricing).

FAQ
Can an AI assistant replace a human executive assistant?
Not fully. AI suits repetitive, rule-based, low-cost-to-correct work such as routine scheduling, triage, first drafts and prep briefs. A human EA is better at gatekeeping, relationships with other EAs and VIPs, sensitive matters, complex travel and events.
What should I hand to an AI assistant?
Scheduling routine meetings, rescheduling, calendar hygiene, inbox triage, first drafts of routine replies, meeting prep briefs, reminders and follow-ups, daily summaries and after-hours coverage, all within written rules.
Which AI assistant works with a human EA?
OpenAssistant’s Coordinator Mode, a live feature, lets a human EA run the assistant on behalf of an executive, using that executive’s calendar and preferences. Vimcal EA and Reclaim’s Delegated Access are also built for EAs, but they speed up scheduling rather than acting on their own.
How do I introduce AI to my EA without making it a threat?
Make the EA the owner: they choose the tool with you, write its rules and supervise it. Agree in advance what higher-value work they will do with the time, start with the tasks they dislike most, and revisit the split every quarter.
