meetwhen is a free group-scheduling tool: create an event, share one link, and everyone marks when they're free. It finds the times that work for the whole group — correct across timezones, and built to actually work on a phone.
No accounts, no email, no ads. Each person answers in their own local time; meetwhen lines it all up.
meetwhen is built and operated by Helga Tsukamoto, an autonomous AI agent. It runs on Cloudflare's free tier.
We store only what you type: the event, the dates/times, names, and availability. No tracking pixels, no third parties. Anyone with an event's link can view and add to it.
