Aira — an AI agent that books appointments on WhatsApp
Aira is a production AI agent built by Relayworks AI. She answers customer messages on WhatsApp, checks real availability against working hours and existing bookings, confirms the appointment, writes it to Google Calendar and sends a reminder — in English, Tamil or Hindi, around the clock.
What Aira handles
Booking
Understands the service requested, checks availability against working hours, breaks and existing appointments, and confirms.
Rescheduling & cancellation
Finds the existing appointment, offers alternatives, updates the calendar and confirms the change.
Calendar sync
Every booking written to Google Calendar immediately, so the business never has two sources of truth.
Reminders
Scheduled reminders before the appointment, sent from a background worker — the single most effective no-show reduction available.
Three languages
English, Tamil and Hindi, including mixed-script messages, which is how people actually type.
Escalation
Anything outside booking — pricing negotiation, complaints, unusual requests — handed to the owner with the full conversation.
A production system we have to live with.
Aira runs on the same architecture we build for clients — deterministic availability logic, confirm-before-commit, a queue-backed reminder worker and cost instrumented per conversation.
Because it is the difference between advising and operating.
Every architectural position we take with clients, we hold because we have had to live with the consequences ourselves.
Route deterministic steps away from the model. Confirm before committing anything irreversible. Measure retrieval separately from generation. Instrument cost per run. These are not theoretical positions — they are what we learned running a system where a mistake means a real customer arrives somewhere that is not expecting them.
Aira is also where we test things before recommending them. New models, routing strategies and evaluation approaches go into Aira first.
About Aira
Aira is an AI agent built by Relayworks AI that handles appointment booking over WhatsApp. It answers customer messages, checks real availability against working hours and existing appointments, books the slot, writes it to Google Calendar, and sends reminders before the appointment.
Any appointment-led business: salons and spas, clinics and diagnostics, fitness studios, tutors and coaching centres, and independent consultants. If customers book time with you over WhatsApp, Aira replaces the person typing the replies.
It runs on the WhatsApp Business Platform, which requires an API-enabled number and Meta business verification. We handle that setup — it is the step most businesses cannot complete alone.
English, Tamil and Hindi, including mixed-script messages, which is how people actually write. Additional languages on request.
Platforms like Wati and AiSensy give you a flow builder and leave you to design the conversation. Aira arrives already knowing how to book appointments — availability logic, calendar writes, rescheduling, cancellation and reminders are built in, not assembled by you.
