ONE CIRCUIT.
NO MORE CONFLICTS.
A circuit copies events from one calendar to another, blocking that time across all your accounts. Set it once; no double-bookings.
Or try the demo below. Pick two calendars and see how a circuit works.

LET OTHERS
BOOK YOUR TIME.
Share your availability without handing over calendar access. Enable public booking with one toggle and Switchboard generates a link you can send to anyone. Slots already blocked by your other calendars are automatically marked unavailable. No manual sync, no access requests.
