KN Booking is a lightweight appointment booking plugin built for salons, barbershops and other small appointment-based businesses. Clients pick a date and time on a calendar, you approve or decline the request, and everyone gets an automatic email. No account with an external service, no bloat.

A built-in setup wizard (Settings > Setup) gets you running in about two minutes: enter your business details, choose your open days and hours, and set your booking rules. Then add the [kn_booking] shortcode to any page.

Free Features:

Interactive calendar with availability management
Booking request management (approve, cancel, delete)
Automated email notifications (new request, approval, cancellation)
Customizable booking form with dynamic fields
Customer profile page for users to view and manage their bookings
Booking Calendar and Booking Profile blocks for the block editor

Optional WooCommerce payments: take payment at booking (required, or pay now / pay later), with price based on booking length

“Add to Google Calendar” link on the booking success message

External Services

OpenAI API (optional)

Only if you enter an OpenAI API key under Settings > Integrations, an AI Analyze button appears on bookings. When an admin clicks it, the customer’s name, the requested date and time, and the booking notes are sent to the OpenAI API to generate a summary and a draft reply. Nothing is sent until you click the button, and nothing is sent if no API key is saved.

This service is provided by OpenAI, L.L.C.:
* OpenAI Terms of Use
* OpenAI Privacy Policy

Google Calendar link (optional)

If enabled, the booking success message shows a link to calendar.google.com with the booking details in the URL. No data is sent from your server; the request is only made if the customer clicks the link.
