CommonGround
Find shared places and taste compatibility by comparing Google Maps lists

CommonGround lets two people compare their saved places from Google Maps to discover what they have in common. Users paste their shared list URLs, swipe through locations, and see matching results across categories like places they've both visited, want to go, or nearby vibes. The app requires no signup and runs entirely in the browser.
Designed for dating or friendship matching, it analyzes actual visit history rather than profile text. The maker built it using AI coding tools in about an hour, demonstrating how place data can reveal compatibility better than traditional dating app prompts.
