What is ChatHub?
ChatHub is a browser extension that lets you use multiple AI chatbots side by side in one interface, so you can compare answers without switching apps. It supports services like ChatGPT/GPT-4o, Gemini, Claude 3.5, Llama, and more. The product is positioned as an all-in-one AI chatbot client for people who work with AI regularly and want a faster workflow.
The extension includes several ways to connect to AI models. You can use your own account if you are already logged into supported services in the browser, use your own API key with official APIs, or use ChatHub’s own AI service through a subscription. That makes it useful both for casual users who want convenience and for power users who want control over model access and billing.
Beyond multi-chatbot comparison, ChatHub adds workflow features like a prompt library, local chat history with full-text search, Markdown support, code highlighting, dark mode, smart web access, custom chatbots through OpenAI-compatible APIs, and keyboard shortcuts. Those features make it more than a simple chat wrapper; it is aimed at people who want organization, speed, and better readability while using AI tools.
Overall, ChatHub is best suited for researchers, developers, writers, and AI enthusiasts who want to compare model outputs and keep their prompts and chats organized. It is also useful for users who already have subscriptions or API access to multiple AI platforms and want to bring them into one place. The extension is designed for browser-based use and emphasizes convenience, flexibility, and side-by-side model evaluation.
