ChatHub is a browser extension that lets you use multiple AI chatbots in a single interface.
The tool solves the problem of switching between different chatbot services by consolidating them into one application. It supports ChatGPT, Claude, Google Bard, Gemini, Grok, DeepSeek, Qianwen, Llama, and other open-source models. Users can chat with multiple bots simultaneously to compare their responses, and the extension provides a keyboard shortcut for quick activation from anywhere in the browser. Conversations are stored locally, with options to export, import, and share discussions as markdown. The interface includes markdown rendering, code highlighting, a prompt library for custom and community prompts, and dark mode support.
The extension suits developers and power users who regularly consult multiple AI models and want to avoid tab switching. It works well for comparing model outputs, testing different approaches to prompts, and maintaining a unified conversation history. The tool is particularly valuable for those who use both API-based services like ChatGPT and Claude alongside free web-based alternatives, or who want to experiment with open-source models without managing separate interfaces.
The project shows active development with support for a growing roster of chatbot services and regular feature additions. The codebase is maintained in TypeScript and React, with build tooling that allows users to compile from source if desired. The extension is distributed through the Chrome Web Store for straightforward installation.
