What does an AI receptionist do?
An AI receptionist answers incoming business calls on behalf of a human receptionist. It greets the caller with your business name, identifies the reason for the call, answers common questions from your FAQ or website, books appointments directly into your calendar, takes messages with the caller's name and phone number, and transfers urgent calls to a team member's cell phone. Modern AI receptionists run 24 hours a day, handle multiple callers simultaneously, speak 30+ languages with automatic detection, and integrate with CRMs and scheduling tools. Unlike a traditional answering service, an AI receptionist doesn't read from a script — it holds a real conversation and adapts to what the caller actually needs. how different AI receptionists handle calls.

What an AI receptionist actually does on a call
On every inbound call, the AI greets the caller, identifies why they called, and decides what to do next based on rules you set during setup. The decision is one of four: answer the question directly, book an appointment, take a message, or transfer to a human.
If the caller asks a question your FAQ answers (hours, address, services, pricing), the AI responds verbatim from your trained knowledge. If they want to book, the AI checks live calendar availability and writes the appointment immediately — no email confirmation loop. If they need a human, the AI transfers to the right team member's cell phone or routes to voicemail with a written summary.
Modern AI receptionists also detect call intent in the first 5–10 seconds. Spam, robocalls, and AI-to-AI loops (where another AI calls yours) get classified and disconnected before they consume your call quota.
AI receptionist vs. human receptionist vs. traditional answering service
The category is most often confused with traditional answering services (which are humans reading from a script) and live virtual receptionists (which are humans on a per-minute model). Here is how the three differ on the dimensions that actually matter for a small business.
| Dimension | AI receptionist | Live virtual receptionist | Traditional answering service |
|---|---|---|---|
| Pricing model | Per-call (predictable monthly bill) | Per-minute (highly variable bill) | Per-minute or per-call with overages |
| Hours | 24/7 | Business hours typical, 24/7 available at premium | 24/7 |
| Concurrent calls | Unlimited | Limited by staffed agents | Limited by staffed agents |
| Booking | Writes directly to your calendar in real time | Takes message, you book later | Takes message, you book later |
| Languages | 30+ with auto-detection | Usually English, sometimes Spanish | Usually English |
| Spam filter | Built-in, ends spam in seconds | Agent must screen manually | Agent must screen manually |
| Starting price | $24.95/mo (Aira) or comparable | $200–$400/mo for 100–200 minutes | $50–$300/mo with usage overages |
Pricing reflects 2026 published rates. Per-minute pricing exposes the buyer to billing surprises on long calls; per-call models cap the per-call cost regardless of duration.
What an AI receptionist can't do (yet)
An AI receptionist can't physically handle a package delivery, walk a guest into a back office, or recognize a regular customer by face. It can't make complex judgment calls that require knowledge outside what you trained it on (legal liability decisions, medical triage that requires a license, emergency dispatch).
It also can't replace the warmth of a long-tenured human receptionist who knows your top 50 customers by name and their backstory. What it can do is answer every call you would otherwise miss, at any hour, in any language — and most small businesses miss 20–40% of incoming calls today.
How Aira handles each of these capabilities
Aira is an AI receptionist built specifically for small businesses with high call volume and predictable billing pressure. Plans start at $24.95/month for 30 calls. The setup takes under 10 minutes — you paste your website URL and Aira ingests your business automatically. The spam filter is on by default. Bilingual (English + Spanish) support is on every plan, and the full 30+ language set is on every plan above Starter.
Aira charges per call, not per minute, so a long call never wrecks your bill. The classifier ends spam and AI-to-AI loops in the first few seconds before they eat into your plan. See the full feature list, pricing breakdown, and side-by-side comparison against the major alternatives.
