HarchSignal

A text the day before, a text an hour before. Dead simple — and it's what drops no-shows the most.

Every appointment booked by the AI triggers two automatic reminders: the morning before, then an hour before the scheduled time. The customer confirms, reschedules, or cancels by simply replying — and a cancellation frees the slot for the waitlist, in real time. You track nothing: the calendar drives.

FAQ

Questions we get

Can the customer just reply "I can't make it"?

Yes: the AI confirms the cancellation, offers to reschedule if the customer wants, and frees the slot. The slot goes to the waitlist right after.

What if I book an appointment outside Signal myself?

As long as it's in the connected calendar, the reminder goes out. Those appointments only get reminders, no AI intake — no risk of double processing.

Two reminders — isn't that too much?

It's the field-tested dosage: day-before to organize, hour-before for immediate memory. No other message is sent to the customer without their action, and STOP is processed in under 24 h.
