ChatHub is a browser extension designed to provide unified access to multiple large language model (LLM) chatbots from a single interface. Users can open and interact with several AI assistants side by side, enabling direct comparison of responses from models such as ChatGPT, Google Gemini, Claude, Bing Chat, and others. The extension supports prompt libraries for saving and reusing frequently used prompts, as well as conversation history management. ChatHub aims to reduce the friction of switching between different AI platforms by consolidating them into one browser-based workspace. It is available primarily as a Chrome extension and supports both free and paid tiers, with premium plans unlocking access to additional models and features. The tool targets individuals, developers, and professionals who regularly use AI assistants and want to evaluate or leverage multiple models without maintaining separate browser tabs or accounts for each service.
