Show HN: PolyGPT – ChatGPT, Claude, Gemini, Perplexity responses side-by-side I built PolyGPT to solve a problem I had: constantly tab-switching between ChatGPT, Claude, and Gemini to compare their responses. It's a desktop app (Mac/Windows/Linux) that lets you type a prompt once and see all three AI models respond simultaneously in a split view. Useful for: - Comparing technical explanations - Getting multiple perspectives on code problems - Fact-checking answers across models The app is free, open source, and runs locally - your credentials stay on your machine.

What other features would make this more useful? https://polygpt.app November 22, 2025 at 01:36AM
