About Cal.ai

Cal.ai is the AI scheduling layer built on top of Cal.com, the open-source Calendly alternative, that enables users to schedule and manage meetings through natural language conversations via email, SMS, or chat. The AI agent reads scheduling requests, checks calendar availability, applies user preferences about meeting types and working hours, and books the appropriate slot—all without the user needing to touch a scheduling page. Cal.ai integrates with Cal.com's full scheduling infrastructure including availability rules, buffer times, location options, and meeting type templates. As an open-source project, Cal.ai is fully customizable and self-hostable for organizations with specific scheduling workflow requirements. It represents the next evolution of scheduling automation, replacing link-based scheduling with conversational AI for natural, flexible meeting coordination.
