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.

Would love feedback from the HN community. What other features would make this more useful?

But this would require API access instead of embedding web apps
