What is Whenn?

Whenn automates external group meeting scheduling. Add participants by email, they connect their Google or Microsoft calendar, and AutoWhenn reads everyone's live availability, finds the best overlapping slot, confirms the meeting, and sends calendar invites — without any further action from the organiser.

Unlike polling tools, Whenn reads live free/busy data from participants' calendars rather than asking them to fill in a grid. The availability used to confirm a meeting is always current, not a snapshot from days earlier.

Whenn is purpose-built for external group meetings — where participants are from different organisations and share no common calendar system. It works across Google Calendar and Microsoft 365, handling mixed-platform coordination automatically. Participants connect their calendar once with no account required.

Free tier: 3 AutoWhenn confirmations per month. Unlimited from £8/month.

For Microsoft 365 users, a full IT approval guide and permissions breakdown is available at meetwhenn.com/microsoft-approval.
