Overlap is a group scheduling tool for the "6 people in a group chat trying to agree on a time" problem. Share one link → everyone paints when they're free on a grid (no account needed) → Overlap ranks the best times → the organiser picks one and it becomes a Google Calendar event, sent to everyone. Built for people tired of When2Meet's 2007-era UI and tired of the manual step after the poll where someone still has to build the invite by hand. Free to use. No signup to respond to a poll ever.

Hey Product Hunt 👋 The thing that pushed me to build this: When2Meet is still the default for "find a time," and it's genuinely great at the hard part (fast drag-to-select, no friction to respond) but the workflow just... ends at a heatmap. Someone still has to interpret it, then go build the calendar invite by hand. Overlap keeps what works about When2Meet and finishes the loop: painting availability → surfacing the best time automatically → one click to create the Calendar event + Meet link. Also rebuilt the interaction for mobile specifically, since most people open these links from WhatsApp//iMessage group chats on their phone, not a laptop. Happy to answer anything, especially interested if the mobile tap-and-drag feels natural to people seeing it for the first time.
