Show HN: Chorus – Ask multiple AIs at once on Mac

Score: 4.8/10 (Innovation: 3, Technical: 5, Documentation: 7, Utility: 4)

Chorus is a native macOS app that sends a single prompt to multiple AI chat websites (ChatGPT, Claude, Gemini, etc.) side by side, using existing browser logins without API keys. It automates each site's UI to type and submit questions, then detects when answers complete, and includes comparison and scoring features. The approach is practical for power users but relies on brittle web automation and faces high maintenance from site redesigns.

Target audience: Mac power users and AI enthusiasts comparing chatbot outputs
