WhatsApp chatbot for physiotherapy: a real calendar, not invented slots

Physiotherapists rarely sell a single visit. They sell a package of five or ten sessions, usually discounted 10-20%, because a full course of treatment typically needs ten to twelve visits spread across several weeks. That turns rescheduling into a routine event rather than an exception, and it is why so many clinic reviews repeat the same complaint: nobody answers the phone, nobody replies on WhatsApp.

Why physiotherapy does not book like a one-off appointment

With ten or twelve visits per package, scheduling stops being occasional and becomes daily work, at any hour, not just during reception hours. A fixed-menu chatbot cannot handle that: it has no idea whether the 5pm slot is still open, and it cannot parse "do you have anything Thursday afternoon?"

An AI agent for physiotherapy can. It checks the real calendar, offers slots that genuinely exist, and confirms the session inside the same WhatsApp or Telegram conversation, day or night. From here on, we mean agent, not chatbot: the distinction the market is already learning is that one answers and the other acts against your actual calendar.

The first visit is not just another session

Before any hands-on treatment, the first appointment includes a full clinical history and physical examination; many clinics ask patients to bring prior imaging or reports. The agent explains this administratively — what to bring, how long it takes, what to expect — without making any clinical call.

The agent's catalogue is loaded from your own clinic's files: real prices per session type. In Spain, for example, a standard session typically runs €35-70, junior sessions €20-30, and specialised work such as sports physiotherapy or pelvic floor therapy €50-70. The agent applies your own discount codes for packages, never invented ones.

Where the agent stops: logistics, never clinical judgement

A physiotherapist cannot diagnose over WhatsApp, and the agent does not try to either. If a message mixes symptoms with a booking request ("my knee hurts, do you have anything tomorrow?"), the agent handles the administrative part and does not interpret pain, urgency, or treatment. That boundary is what makes the agent trustworthy, not a limitation to apologise for.

There is a regulatory reason too: clinical data is a special category under GDPR, and the accepted guidance is that WhatsApp should carry only non-clinical logistics — scheduling, reminders, confirmations — never clinical content. The agent is built inside that boundary from the first message, which matters just as much for a package tracked over weeks as it does for a single visit.

What the agent still does not do

It books new sessions against real availability, but it does not cancel or move an existing confirmed appointment — that stays with reception. It can tell a patient your clinic's cancellation policy — free with more than 24 hours' notice, a 50% charge between 12 and 24 hours, the session lost and deducted from the package under 12 hours — because that is catalogue information, not an action on your calendar.

It also does not analyse photos of an injury, notify your staff internally, or connect to your clinical records system. Those stay firmly with your team. And while a ten-session package practically begs for a reminder before the next visit, that does not exist yet — it is exactly the feature we are building, and it is worth being upfront that it is not live today.

Before connecting it to your real calendar, test it with the cases that usually break a flow: requests mid-package, questions about specialised pricing, messages that mix pain with availability. A trustworthy agent asks for little, stops at anything clinical, and never invents an open slot.
