In their own words
Ari
Ari is an AI scheduling assistant that users CC on an email thread to find times that work for participants and arrange meetings. With permission, it reads Google Calendar and Microsoft 365 calendars and can create, update, or cancel events. It processes email content in threads where it is copied to identify scheduling requests. Listed services include Gmail, Outlook, Google Calendar, Microsoft 365, Zoom, Google Meet, and Microsoft Teams. Ari's Mac and iPhone apps can record and transcribe meetings, summarize them, and help book follow-ups; recording starts only when the user presses record. The macOS app keeps recordings and transcripts on the device unless cloud features are used. The Free plan allows 10 meetings total and one Google and one Microsoft calendar. Basic costs $24/mo, and Premium costs $39/mo. The maker says email content is sent to Anthropic’s Claude API for scheduling-intent processing and is not retained beyond what is needed to complete the request. Ari may misunderstand intent or suggest incorrect times, so users must review and confirm meetings.
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+.
