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.
