Clara vs Lumo

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.
