Clara vs Sarra

Clara is a web-based AI scheduling assistant that manages meeting arrangements through email. It reads email threads, proposes times, handles replies, and confirms meetings; if invitees do not respond, it follows up in the thread. For rescheduling, it finds another time, cancels the original invite, and sends an updated one. It also coordinates group meetings, tracks participant responses, and supports calls across time zones. Users can set scheduling windows, buffer times, meeting types, priority contacts, and communication preferences. Clara works natively with Google Workspace and Microsoft Outlook and Exchange; its homepage also displays Zoom and Teams among associated tools. The maker says no human reads scheduling emails and that customer data is not used to train its models. Its privacy policy names OpenAI, Anthropic, and Google as AI providers that may receive email and calendar content to generate responses. The Free plan is free for 14 days and five meetings. Standard is $80 a month for 30 meetings; the free-plan limit stops further scheduling until upgrade.

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.
