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?

Ninja Chat offers this.

Open Web UI already provides this as a self hosted web solution.

One good feature I like is ability to generate multiple responses from different models and merge it using one default model.
