What is it?
ChatHub is a browser extension for Chrome and Edge that lets you talk to several AI chatbots from a single app. It supports web-based bots like ChatGPT, Gemini, Claude, Grok, DeepSeek and Qianwen, as well as ChatGPT and Claude through their APIs, along with open-source models such as Llama.
You can send the same prompt to multiple bots at once, which makes it straightforward to compare their answers side by side. A global shortcut opens the app from anywhere in the browser. Conversations are stored locally, and the extension includes a prompt library, Markdown and code highlighting, dark mode, and export and import of your data.
The project is written in TypeScript with React. It can be installed from the Chrome Web Store or built from source with Yarn and loaded as an unpacked extension.
