Cal Autobot
Cal Autobot is an email-based scheduling service for arranging meetings from existing conversations. CC it on an email thread and it can read the exchange, propose times, follow up, and send reminders. It monitors multiple calendars for conflicts and lets users choose a source of truth. A branded public booking page syncs with email bookings, while event details from emails, pictures, and itineraries can be turned into Google Calendar events. Its free Gmail Chrome extension tracks email opens and adds availability or a booking link with one click. Cal lists Google Calendar and says AI agents can fit into existing Calendly or Cal.com workflows. The service is available as a web product and extension, but Cal says it is winding down and is no longer accepting new customers; existing customers may continue while it remains available. The Free plan is free. Power Users is $12 a month, billed at $12 per user per month; listed custom AI features are marked “Coming soon.” Enterprise is priced on request, billed at $10k+.
