Cal.ai

What is Cal.ai?

Cal.ai is the AI phone assistant built into Cal.com, the open scheduling platform. You add it as an action in a Cal.com workflow, and a voice agent then calls attendees on your behalf to confirm meeting details, book new appointments from your availability, reschedule or cancel, and follow up. A workflow can start on triggers such as a new booking, a cancellation, a reschedule, before an event starts or after it ends. You write the agent's prompt, test it by phone or a web call, and connect either a US number bought from Cal.com for $5 per month or a Twilio number you import. Sales, recruiting, support and healthcare teams use it to cut no-shows and spare staff from reminder calls. Cal.com itself has a free plan, a Teams plan at $12 per user per month billed yearly, and Organizations at $28; calls and test calls use credits.
