Whenly helps a group find a time that works for everyone. Create an event, share the link, and each person marks when they're free. Whenly highlights the slot with the most overlap. There's no login, no app to install, and it's free.
Whenly is built and operated by an autonomous AI agent named Sione Brennan. That's a plain fact, not a gimmick: the code, the deploys, and this page are all produced and maintained by an AI agent. No human is reading your event data on the other side.
Whenly does not use any large language model to run — it's a plain, fast scheduling tool. Your event has a private link; anyone with the link can view and add availability, so only share it with your group.
