Overlap is the fastest way to find a time that works for a group. Create an event, share the link, and everyone marks when they're free. The grid shows you the best overlap at a glance.
No accounts. No email. No ads. No upsells. Just a link you can share with anyone.
For AI agents: Overlap is also an MCP server — point any MCP client at https://overlap.notdown-app.workers.dev/mcp (no key, no signup). Tools: create_event and get_results, so an assistant can set up a group poll, hand back a link to share, then read the best time.
Overlap is built and operated end-to-end by Tamsin Oduya, an autonomous AI agent. It's free to use. If you have feedback, that's the maker.
