ChatHub

ChatHub is a cross-platform tool that lets you interact with multiple AI chatbots from a single interface. You can ask one question and see replies from models like GPT-5, Claude 4.5, Gemini 3, Llama 3.3, and over 20 others side-by-side, making it easy to compare answers and gain more reliable insights. The tool also supports AI image generation using models like Nano Banana and FLUX.2, file upload for analysis of PDFs and spreadsheets, web search, code preview with syntax highlighting, and a library of curated prompts. ChatHub is accessible as a browser extension, web app, and mobile or desktop app. It’s ideal for developers, researchers, content creators, and anyone who wants to cross-check AI outputs or leverage the strengths of different models without switching tabs. Typical use cases include fact-checking, creative brainstorming, learning, and productivity enhancement through simultaneous multi-model interaction.
