I started with small internal tools, and now I’m “vibe coding” multiple highly personalized apps. As I iterated between Claude Code (implementation) and ChatGPT (ideation / thinking), I kept running into the same problem.

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.
