Summary

Happenstance is an AI people-search engine that searches an existing network and surfaces paths for introductions. It scores relationships using email headers, meetings, connections, follows, and contacts, then ranks people by how well they know one another. Results identify matched people, explain the match, and show a direct, friend, or group path. Supported sources include Gmail, Outlook, Google Calendar, Google Contacts, LinkedIn, Twitter, and Instagram. Friends mutually share networks, while groups pool networks for teams, funds, cohorts, or communities; groups are free and unlimited. Happenstance also provides a REST API, MCP server, OpenAPI specification, and CLI, and works with ChatGPT, Claude, Claude Code, and OpenClaw. Its iPhone app offers natural-language search, ranked paths, saved lists, introduction drafting, and network updates. Email and direct-message content and attachments stay off its servers; it uses sender, recipient, and timing metadata. The Free plan has Chat usage limits. Pro is 24.00 USD per year, while Team is 24.00 USD per seat per month.
