Two-way
The AI books. Your team takes the rest.
With Booking by text on, the AI answers appointment texts by itself, and hands anyone who asks for a person to your team. For other texts, including photos and voice notes it reads and transcribes, it drafts a reply for your team to send.
I can do 4:00 PM or 5:15 PM tomorrow. Which would you like?
Thanks, I’ve passed this to the team. Someone will text you back soon.
Thanks for the photo — that looks like a leak at the trap. Want us to book a plumber’s visit?
Number provisioning
Your number, your sender.
Text from a number you own — a new one, or one you already have on Twilio.
Buy a number in the dashboard
Search for a number and buy it from the dashboard. Every text comes from the same number, so customers recognise you and can reply.
Good for
US, Canada, UK and Australia numbers
Link your existing number
Already have a number on your Twilio account? Bring it in with Sync Twilio and link it to an assistant — no new number for customers to learn.

A2P 10DLC & opt-outs
Registration support for A2P 10DLC, plus STOP/START opt-out handling and a do-not-contact list built in.

Business texting in the US · staying carrier-compliant
Yes. Buy a number in the dashboard (US, Canada, UK or Australia), or bring in a number you already have on your Twilio account with Sync Twilio. Every text comes from that number. US business texting also needs A2P 10DLC registration, which you can submit from the dashboard.
Yes. A customer can reply hours later and Aiva Chat picks up from the thread: it reads the recent messages, including the reminder they are replying to.
Aiva Chat replies in the language the customer writes in. For suggested replies, it can also read images and transcribe voice notes sent by MMS.
Only to appointment texts, and only once you turn on Booking by text for an assistant (it answers texts sent to that assistant’s numbers). It is off until you switch it on. You choose whether it answers appointment texts only (the default) or every text. Other texts wait in your inbox, where Suggest a reply drafts an answer for a person to read and send. Every AI reply is marked in the inbox, and the AI runs on your own OpenAI key. It also sends booking confirmations and appointment reminders by itself (up to two of 24 hours, 2 hours or 1 hour before, inside 8 AM–9 PM quiet hours). US and Canadian numbers need approved A2P 10DLC registration.
Yes, with Booking by text switched on. Customers text your number and the AI finds a free time, books it, moves it, cancels it or adds them to the waitlist, then confirms in the same thread with their own link to the booking. It finds bookings by the number they text from. Services that take a deposit aren’t booked by text: the reply sends your booking page link so they can pay there. Reminders then say they can reply to change or cancel, and replying C still confirms.
Yes. Any conversation the AI is handling can be taken over from the inbox. When someone on your team replies, the AI pauses on that conversation for 2, 12 or 24 hours (your choice), and Let AI reply hands it back. If a customer asks for a person, the AI tells them the team will text back, marks the thread Needs you and notifies you. Limits keep it in check: up to 20 AI replies per customer a day by default (you can set 5 to 50) and 300 per assistant.
Twilio. Your number lives on Twilio, and we support A2P 10DLC registration for business texting in the US.
Yes. Replies of STOP and START are handled automatically, and you can keep a do-not-contact list on top.
Aiva Chat is a flat plan from $49/mo with SMS included on every plan. The texts themselves run on your own Twilio account, so Twilio bills you directly at its published rates — Aiva Chat adds no per-message charge or markup.
