AI scheduling agents for Slack, Telegram, email, and phone
Install a Cal.com agent in Slack or Telegram to check availability, book, reschedule, and cancel meetings without leaving the conversation.
Trigger outbound calls that confirm bookings, remind attendees, and reschedule no-shows, with custom prompts controlling tone, personality, and call goals.
Trigger AI phone calls from the events you already automate, such as form submissions, no-shows, and cancellations, and blend them with email and SMS steps.
Transcripts attach to the booking record, and metrics cover call completion, booking rates, and customer sentiment for script optimization.

Ask a question in plain language and get a cited answer assembled from documents, tickets, wikis, and messages across every connected system, with permissions respected.
Reusable agents handle multi-step workflows such as onboarding, account research, or incident follow-up by orchestrating actions across business apps.
Glean automatically picks and routes requests to the right model and reasoning level, giving teams access to 40+ LLMs through a single governed gateway.
Draft on-brand documents, summarise meetings, analyse data, and create content grounded in company context rather than generic model knowledge.
