What is ChatHub?
ChatHub answers a question every AI user eventually asks — which model is right? — by letting you ask several at once. Type a prompt and watch GPT, Claude, Gemini, Llama and other models answer in parallel panels, making differences in style, depth and accuracy immediately visible. A browser extension brings the comparison view to any page, and chat-with-files and web access round out daily use.
It is a practical tool for writers, developers and researchers who sanity-check important answers against a second model, and for anyone deciding which subscription deserves their money. Free use covers a couple of models with daily limits; the paid plan unlocks all models, higher quotas and multi-model panels. ChatHub will not replace a primary assistant for long projects, but as a comparison instrument it is excellent.
