Ari vs Sarra

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.

Sarra is a web-based AI scheduling assistant that coordinates appointments through email. Add it to an email thread and it can suggest times, follow up, and send a calendar invitation after attendees agree. You can also name a particular time in an email for Sarra to check and book, or share the personal booking link included with each plan to show live availability. It connects with Google Calendar and Microsoft Outlook. Sarra can generate Google Meet links through a connected Google account and Teams links through an eligible Microsoft 365 work or school account. It does not connect to Zoom or create unique Zoom meetings, but can insert a Zoom URL saved in Settings. Monthly meeting allowances apply per seat, and scheduling pauses once an allowance is reached until renewal or upgrade. Free includes three meetings per month per seat, one saved meeting type, one calendar connection, and one follow-up nudge every two days. A single external sender is also limited to 10 inbound requests per day on Free, separate from the monthly allowance. Group scheduling is available on Gold and above.
