What is Cal.AI?
Cal.ai is Cal.com’s AI scheduling assistant that automates meeting coordination through phone calls and calendar workflows. It can book new meetings, confirm details, reschedule, cancel, and follow up with participants on your behalf. The product is built to reduce back-and-forth scheduling and keep your calendar current even when you are unavailable.
It is designed to work inside Cal.com workflows, where you choose triggers like a new booking, a canceled event, a reschedule, or an upcoming meeting. You can connect a phone number, configure the agent prompt, and test the assistant before putting it to work. The website also notes that both web calls and phone-number calls consume credits.
Cal.ai is aimed at people and teams who spend time coordinating meetings, especially those who want scheduling handled automatically rather than manually. It is also useful for teams that already use Cal.com and want an AI layer for voice-based outreach and follow-up. Because it can operate 24/7, it is positioned as a hands-off scheduling tool for busy calendars.
Cal.com also presents related scheduling agents across channels like Slack, Telegram, Email, and the command line, but Cal.ai itself focuses on workflow-based scheduling through calls and prompts. The website emphasizes privacy, calendar sync, and native integration with existing calendar tools. In practice, that makes it a fit for users who want an assistant that can act on scheduling tasks, not just suggest times.
Cal.AI pricing
Pricing model: Freemium
Cal.ai uses a credit-based pricing model. The help page says calls are charged at 29 credits per minute, which equals $0.29 per minute. Testing also consumes credits, including both web calls and phone-number calls. For phone numbers, Cal.com says you can buy a US phone number for $5 per month, but only US numbers are sold directly; for other countries, you must import your own Twilio phone number. The website does not describe a free tier for Cal.ai itself on the help page, but it does note that some agent integrations like Slack and Telegram are free to use or free to install while requiring a Cal.com account.
