The short definition
An AI receptionist is a program that picks up when a customer calls, chats or messages a business, understands what they say, and replies in natural language, by voice on the phone (the phone part is sometimes sold as an AI voice agent) and by text everywhere else. Instead of following a fixed script or a press-1-for-sales menu, it uses a language model to hold a real conversation.
What separates a receptionist from a plain chatbot is the front-desk job: answering questions about the business, taking the caller's details, booking appointments and knowing when to get a person. An AI receptionist is built to do those things, on every channel a customer might use.
What an AI receptionist does
Day to day, an AI receptionist like Frontivo.io handles the same tasks a front-desk employee would:
- Answers calls and messages instantly, 24 hours a day, including nights, weekends and holidays, with no hold queue or busy signal within the plan allowance.
- Answers questions about hours, prices, services, service area and policies, using the business's own information.
- Qualifies leads by asking what the customer needs, how urgent it is and where they are, and saves the answers with their contact details.
- Books appointments by checking real open times on the business's calendar and confirming the details back to the customer.
- Recommends products and services the business offers and captures the buyer for the team to close.
- Hands off to a person when the customer asks for one or the situation calls for it: a live call transfer, or a detailed message and an alert.
- Keeps a record: every conversation is transcribed and summarised in an inbox the team can read and take over from.
How is it different from a chatbot, an IVR or a virtual receptionist?
The term gets used loosely, so it helps to separate the things it is often confused with.

| Option | Who answers | Channels | Books appointments | Cost model |
|---|---|---|---|---|
| Phone menu (IVR) | Recorded prompts, press 1 or 2 | Phone | No | Part of the phone system |
| Website chatbot | Scripted or AI text replies | Website chat | Sometimes, via a link | Monthly software fee |
| Virtual receptionist | Live people at an answering service | Phone (sometimes chat) | Usually into a shared calendar link | Per minute or per call, plus a monthly base |
| AI receptionist | Conversational AI trained on the business | Phone, website, text and messaging apps | Yes, on the real calendar | Flat monthly plan with usage included |
A virtual receptionist is a human service: real people answer on the business's behalf, usually from a shared team, and bill by the minute or the call. An AI receptionist is software, so it answers instantly, handles many calls at once and costs the same each month. The two can be compared in detail in AI receptionist vs virtual receptionist.
A chatbot usually lives only on a website and often follows a script. An AI receptionist speaks on the phone as well, and treats chat, text and social messages as the same conversation with the same knowledge.
How does an AI receptionist work?
Under the hood, four pieces work together on every call or message. The full walkthrough is in How AI receptionists work; here is the outline.
- 1Speech recognition turns the caller's voice into text in real time (on chat and messaging this step is skipped).
- 2Retrieval searches the business's private knowledge base (services, prices, hours, policies, FAQs) for the information that matches the question. This is called retrieval-augmented generation, or RAG, and it is why a good AI receptionist doesn't make things up: it answers from what the business wrote down.
- 3A language model composes the reply, asks the next qualifying question, or decides to book, transfer or take a message.
- 4Text-to-speech reads the reply back in a natural voice on the phone, while chat and messaging get the text directly. Meanwhile the transcript, the lead and any booking are saved to the business's dashboard.
Who uses an AI receptionist?
Any business that loses customers when the phone isn't answered. That is most local service businesses: plumbers, HVAC and electrical companies, roofers and contractors, cleaning and pest-control companies, auto repair shops, salons, dental and medical offices, veterinary clinics, law and accounting firms, insurance agencies, real estate teams and property managers, restaurants and online stores.
What they have in common is that calls turn into appointments or jobs, staff are busy doing the work rather than sitting by the phone, and a lot of calls arrive after hours. Frontivo.io publishes an industry page for each of these with a sample conversation and setup notes.
What an AI receptionist can't do
Being clear about the limits is part of choosing well.
- It is not a person. It never pretends to be one, and a customer who wants a human should be able to get one, which is why handoff matters.
- It only knows what it has been given. If the business hasn't entered its prices, the receptionist can't quote them; a good one says so rather than guessing.
- It doesn't replace the work. It books the job, qualifies the lead and writes up the call; the team still does the plumbing, the consultation or the haircut.
- Some products don't take payments or sign healthcare business associate agreements. Frontivo.io, for example, does neither today (it shares your own secure payment link instead), and says so on its Why Frontivo.io page.
How much does an AI receptionist cost?
Most AI receptionists are sold as a flat monthly subscription with an included allowance of minutes or conversations, rather than per minute like a human answering service. Frontivo.io's all-in-one plans run from $299 (Starter) to $549 (Growth; opens soon, reserve it at no charge) per month, single-channel plans start at $99, and every plan starts with a 14-day free trial. The cost guide, How much does an AI receptionist cost?, explains what drives the price and how to compare plans.
Is an AI receptionist right for your business?
It is worth trying if you miss calls during the day, get calls after hours, book appointments over the phone, or answer the same questions many times a week. It is a weaker fit if every call needs a human decision on the spot, or you want live people answering under your brand.
The quickest way to find out is to talk to one. Frontivo.io's own AI receptionist answers the live demo on the homepage, and a 14-day free trial with no credit card is at /signup.
