First AI Employee vs. Aira: flat price vs. call caps

What happens to the thirty-first call on the day your phone finally won't stop? Aira and First AI Employee are both AI receptionists for small service businesses that book jobs and send you a summary after each call. They split on two things: who does the setup and how you get charged. Aira is self-serve and bills per call with hard call caps on every plan. First AI Employee is built and run for you at one flat price with no call caps and overage off by default. If you have ever lost a customer because you were under a truck or on a job, the cap is the detail to look at first.

The short version

First AI Employee is the stronger choice when you want the work handled and a bill that does not move, and the cap is the reason. In fairness, Aira starts low at $24.95 a month and is month-to-month with no setup fee, which we'll grant. But that entry plan caps you at 30 calls, and 30 calls is one busy day for a lot of trades. Every Aira plan carries a hard call cap (Starter 30, Premium 90, Pro 300, Scale 600), and once you pass it Aira bills per-call overage on top, from $1.50 a call on Starter down to $0.70 on Scale. There's also no free trial stated to test it first. So the cheapest plan holds up right until the day you need your receptionist most, then starts charging by the call on top of the monthly fee. First AI Employee is done-for-you: the team builds your receptionist, has it answering your calls in minutes, and runs it, all for a flat $99 to $399 a month (Essential is $99 for 400 minutes) with no call caps and no setup fee: you size the plan by minutes, and no overage bills unless you opt in. Flat beats cheap-and-capped the moment the phone gets busy, and the calls a cap turns away are jobs going to whoever picks up instead.

What the call caps leave out

As of June 2026, Aira's pricing page sells its plans in fixed blocks of calls: Starter is $24.95 a month for 30 calls, Premium is $59.95 for 90 calls, Pro is $159.95 for 300 calls, and Scale is $299 for 600 calls. Once you hit the cap, per-call overage kicks in on top of the monthly fee, from $1.50 a call on Starter down to $0.70 on Scale. That means the cheapest plan is fine right up until the day you actually need your receptionist most, and then every extra call carries its own charge. First AI Employee has no call caps at all. You pick a plan by the minutes you expect (from 400 up to 2,000) and a busier month does not change the price you agreed to; overage exists only if you opt in. The full plan list is on the pricing page.

Done-for-you vs. setting it up yourself

Aira is self-serve, so the build and the upkeep are your job. First AI Employee does that for you: the team sets up the receptionist around your business, has it answering your calls in minutes, and keeps it running. If you would rather spend the afternoon on paying work than configuring a phone agent, that is the practical difference. The how it works page walks through it.

The integrations are part of that upkeep. As of June 2026, Aira states on its own ServiceTitan setup doc that the connection 'runs through Zapier' and that 'a native ServiceTitan integration is on the roadmap.' Today every integration is Zapier-mediated, so getting calls into trade software means a separate Zapier account, field mapping and often a paid plan. First AI Employee also uses Zapier as a fallback, while several managed tools connect from the dashboard. Its direct Jobber adapter is built but not open to customers yet, and Housecall Pro has no direct customer connection yet. We say which route is live and which vendor plan it requires before you reach the mapping screen.

Texting customers and trying it first

Aira texts booking links and summaries, but it does not publish a texting allowance you can size a month against. First AI Employee includes one shared inbound-and-outbound SMS pool, 2,000 messages on Basic and 4,000 on Standard, inside the same flat price, so a confirmation or a follow-up on a missed call is a number you can count. First AI Employee does not offer an AI text conversation. Aira also does not appear to offer a free trial anywhere on its site, while First AI Employee gives you a 7-day free trial before you commit. See what is included on the features page.

One more thing for an owner who lives on the phone: as of June 2026, Aira lists no phone support. Its pricing page lists support as chat and email on the lower plans and 'priority support' on Pro and Scale, but no voice line on any tier, including the $299 plan. A company that answers your phones is one you can reach only by chat or email when the agent needs a human mid-shift.

In fairness: Aira's entry price is low at $24.95 a month, it is month-to-month with no setup fee, and you get the same features on every plan.

If you want a receptionist with no call caps, built and run for you at a flat rate with published minute allowances, you don't have to commit on a pricing page. Put it on your own line for seven days, free, and hear it answer your callers before any cap can get in the way. Start the free trial and decide with your own ears.
