Match people who want to exchange letters or messages based on shared interests and languages.
The prompt
Copy this prompt and paste it into Claude, Cursor, ChatGPT, Codex, or any AI tool connected to Hatchable via MCP.
Build a penpal matching service. Users sign up with: name, age range, location (country), languages spoken, interests (select multiple from a list like Reading, Travel, Cooking, Music, Science, Art, Sports, etc.), and a short bio about what they'd like to write about. A matching algorithm suggests compatible penpals based on shared interests and complementary languages. Users can browse suggestions and send a "let's connect" request. When both parties agree, they're matched and can exchange messages through an in-app messaging system. Include a profile page and a matches list. Warm, letter-writing-inspired design with a vintage postal aesthetic. Deploy it on Hatchable when done.
