Hey Product Hunt 👋
I am Usman Ghani and I found that quickly comparing multiple LLMs is very crucial as there a so many providers today and everyone has their strong and weak points.
You can compare GPT-4, Claude, Gemini, etc., tune parameters, and analyze responses side-by-side — all in one clean interface.
It’s free for now — I’d love your feedback and ideas for what to add next!
