The booking flow

One thread,
from hello to booked.

  1. 1

    They text your number

    The same number that’s already on your door, your Google listing, your business card. Nothing new to learn or install.

  2. 2

    Slotsetter answers with real openings

    Cynopic’s AI reads your live calendar — honoring your hours, buffers, and staff — and offers slots that actually work.

  3. 3

    The slot books itself

    Confirmation, calendar invite, reminders, and rescheduling — all handled in the same thread while you keep working.

Two-way sync

Booked once.
Everywhere at once.

The moment a slot is confirmed by text, it exists on every calendar you and your staff live in — and if you block time anywhere, Slotsetter stops offering it. Both directions, in seconds.

Service setup

Your services,
your rules.

Durations, buffers, prices, and who does what — set once in the app. The AI never offers a 4:45 exam when Dr. Patel needs fifteen minutes of chart time, and never books the hygienist for a crown she doesn’t do.

  • Buffers are sacred. Chart notes, room turnover, and travel time are built into every offer.
  • Provider-aware. Patients can ask for Dr. Patel by name; Slotsetter checks her calendar, not just the practice’s.
  • Priced up front. Quotes land in the thread before the booking, so nobody’s surprised at the front desk.

Who it’s for

Made for calendars that
fill up by hand today.

handled in the same thread.

Orthodontists, med spas, financial advisors, real estate agents, pool services, pet clinics… if your week is a wall of appointments and your customers already reach you by text, Slotsetter speaks their language — from first hello to last-minute change.
