Hey Product Hunt! šŸ‘‹ I'm Nathan, and I built PolyGPT to solve a frustration I had every day: switching between ChatGPT, Claude, and Gemini tabs to compare their answers. **What is PolyGPT?** A free desktop app that lets you query multiple AI models at once and see their responses side-by-side in real-time. **Why I built this:** - Tired of tab-switching between AI tools - Wanted to compare different models' perspectives on the same question - Needed a faster workflow for coding, research, and problem-solving **Key features:** āœ… Side-by-side comparison of ChatGPT, Claude, and Gemini āœ… Type once, get 4 responses simultaneously āœ… 100% free and open source āœ… No login to my app - use your own credentials āœ… Completely private - runs locally on your machine āœ… Cross-platform: Mac, Windows, Linux **Tech stack:** Electron **What's next:** - More AI models (suggestions welcome!) - Better diff/comparison tools I'd love your feedback! What features would make this more useful for your workflow? šŸ”— Website: https://polygpt.app šŸ’» GitHub: https://github.com/ncvgl/polygpt Thanks for checking it out! šŸ™
