What's Up In is a family of free event calendars, one per city. Each city’s site gathers upcoming events from that area’s own public sources (venue calendars, museums, libraries, community groups, universities, ticketing pages and more) into one list you can filter by date, category, neighborhood or price. Every event links back to its original listing, so you always buy tickets or check details at the source.
This page, whatsupin.ai, is the front door: pick your city, or search every city at once for a performer, festival, conference, big show, game or race. 59 cities have a site today, out of 59 we are building; new cities start as “beta” while their local sources are still being added.
Each city is rebuilt from its sources on a schedule. Each city’s coverage page lists those sources, how fresh each one is, and how complete and accurate the listings are, measured by re-reading samples of the original listings. The cross-city numbers are on the coverage page.
There are no accounts, no paywall and no ads on this page. You can sign up for a weekly email per city if you want one, and unsubscribe from any issue. What we store and why is in the privacy policy.
AI assistants such as Claude and ChatGPT can search the same listings through our free MCP server, so an answer about what’s on in your city can come with real dates and links instead of guesses. See For AI assistants and Developers & API.
