Where they really differ
- Judgment and relationships. A person can read a tone, notice something is off, and build trust over years. An AI employee follows rules and will miss what is not in them.
- Availability. An AI employee works when messages arrive, any hour. A person works the hours you agreed, and takes holidays and sick days.
- Consistency. An AI employee does the 400th task like the first. A person varies with attention and mood, which is also how they catch things.
- Onboarding. A person learns by shadowing and asking. An AI employee learns from written knowledge and rules. If you have no written process, onboarding it is the hard part, and writing it down helps your human team too.
- Failure mode. A person fails by forgetting or misunderstanding, and tells you. An AI employee fails by being confidently wrong in a situation nobody wrote a rule for. This is why approvals and a never-do list exist.
- Cost shape. A virtual assistant is typically paid by time. An AI employee has a setup cost and a monthly cost that does not rise with volume the way hours do. Which is cheaper depends on your volume. Put your own numbers into the cost calculator.
Which task goes to whom
These are our recommendations, based on how the work behaves, not on a study. Adjust them to your business.
| Task | Best owner | Why |
|---|---|---|
| Sorting an inbox into needs-you, can-wait, can-be-handled | AI employee | Rule-based, high volume, easy to review. |
| Replying to a first-time enquiry | AI employee drafts, person approves | Speed matters, but tone and promises need a human check. |
| Handling an upset long-standing customer | Person | Relationship and empathy. AI can summarize the history. |
| Researching ten companies before a call | AI employee | Repeatable, sourced, and a person reviews the brief. |
| Negotiating a contract with a supplier | Person | Judgment, leverage and consequences. |
| Chasing overdue invoices politely | AI employee drafts, person approves | Repetitive, but money and tone are involved. |
| Booking a physical venue or calling a vendor | Virtual assistant | Needs a phone call or a human relationship. |
| Posting the weekly social updates | AI employee drafts, person approves | Consistent cadence, brand voice reviewed. |

Using both
The pattern that works best in practice is a division of labor. The AI employee does the repetitive preparation: sorting, drafting, researching, updating records. The person does the parts that need judgment: approving what goes out, handling exceptions, talking to people who matter. Done well, the assistant spends less time on routine and more on the work only a person can do.
That is also how we design every employee: it prepares, and a named person decides. Our executive assistant role is built to work alongside a human assistant, not instead of one.
When each is the wrong choice
An AI employee is the wrong choice when the task is rare, when most cases are exceptions, when you cannot say what good looks like, or when a mistake would be serious and irreversible.
A virtual assistant is the wrong choice when the work is a high volume of near-identical tasks that need to be done at all hours, or when the main need is consistency rather than judgment, and the cost of people-hours would outweigh the value.
How we wrote this
We build AI employees for a living, so we have a point of view. Where a point favors us, we say so. We have no customer results to publish yet, so we publish none: every claim on these pages is either reasoning you can check, a fact about how our own product works, or a clearly labeled example.
