Never miss a customer call again. CallnAI gives your business an AI receptionist that answers when you can't — on a job, with a client, after hours — takes the message, and puts every call in one inbox on your phone. Built for people who can't stop to pick up: plumbers and contractors, salons and barbers, therapists and clinics, and every small business that lives on its phone. HOW IT WORKS 1. Pick your business number in the app. It's ready to answer in about a minute. 2. Tell your agent about your business: your hours, services, prices, and what counts as urgent. Start from a template for your trade and edit it in your own words. 3. Keep the number you already have. Forward the calls you miss to your agent with a short carrier code, and the app shows when forwarding is working. EVERY CALL, AS A MESSAGE - Who called, what they need and when to call them back, in the caller's own words - A summary, the recording and the full transcript of every call - An inbox that shows what still needs you, so nothing slips through. Tap Done when it's dealt with. URGENT CALLS REACH YOU FIRST Burst pipe, same-day cancellation, a client who can't wait: you decide what's urgent, and those calls send a time-sensitive alert straight to your lock screen. YOUR AGENT CALLS FOR YOU Have your agent call a customer back, confirm an appointment or follow up, then read how it went. You get the result, the recording and the transcript. IT REMEMBERS YOUR CUSTOMERS Everyone your agent talks to is saved in Contacts with their name, your notes and what happened last time, so returning callers aren't asked the same questions twice. SPAM STAYS OUT OF YOUR WAY Robocalls and junk calls are marked as spam so they don't crowd out real customers. BOOKINGS Connect Google Calendar from the web dashboard and your agent can book appointments into your free times. CALLNAI PRO Download free and try your agent with free minutes. Pro gives you your own business number and 100 minutes a month, for incoming and outgoing calls. Payment is charged to your Apple ID account at confirmation of purchase. The subscription renews automatically unless it's cancelled at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.
