Chorus

Chorus is a native macOS app that allows users to send a single question to multiple AI chat services at once, viewing their answers side by side for easy comparison. It supports built-in AIs like ChatGPT, Claude, and Gemini, and allows adding any OpenAI-compatible model or AI accessed through their websites. Chorus types the question into each AI's site and fetches responses directly, without needing API keys. It includes features like quick prompt access, focus mode, and image input support.
