Cal.ai is the AI phone-calling feature built into Cal.com, the open-source scheduling platform founded in 2021 by Peer Richelsen and Bailey Pumfleet. Rather than a standalone product, Cal.ai is a Workflows add-on that places outbound calls on a user's behalf to handle scheduling-related conversations.
The feature uses voice agents to call leads who have not booked, confirm upcoming appointments, and follow up with no-shows, adapting tone and script to match a business's brand instead of reading a fixed script. It plugs directly into existing Cal.com booking workflows, so a call can reschedule or cancel a meeting on the calendar in the same action.
Cal.ai fits teams already running scheduling through Cal.com who want to cut down on manual reminder calls, sales teams, clinics, and service businesses handling no-show-prone appointments. Cal.com itself is free for individuals, with Team ($15/user/month) and Organization ($37/user/month) plans; AI phone minutes are billed separately at $0.29 per minute on top of whichever plan a workspace runs.
