ChatHub: All-in-One Multi-AI Chatbot Client

ChatHub is a powerful browser extension that consolidates the fragmented world of AI chatbots into a single, unified interface. Instead of juggling dozens of browser tabs, users can access ChatGPT, Bing Chat, Google Bard, Claude, and a growing roster of open-source models—including advanced options like GPT-4.1, Gemini 2.5 Pro, and DeepSeek R1—all from one convenient dashboard. This makes it effortless to run the same prompt through multiple LLMs at once and compare their responses side by side, helping users identify which model performs best for a given task. Beyond simple multi-chat functionality, ChatHub is packed with productivity features designed for power users. A robust prompt library lets you save, organize, and pull from community-created prompts, while conversation history ensures nothing gets lost. Built-in tools like an AI Image Generator, Webpage Summarizer, and AI Translator extend the extension's utility far beyond text chat, turning it into a genuine all-purpose AI toolkit accessible right from your browser toolbar. Whether you're a developer debugging code with syntax highlighting, a researcher cross-checking answers, or a writer brainstorming ideas, ChatHub streamlines the entire AI workflow. Its lightweight, keyboard-shortcut-activated design means you can summon it instantly on any webpage, making it a seamless companion for anyone who regularly relies on multiple AI models to get work done.

Install the ChatHub extension on a Chromium-based browser like Chrome, Edge, or Brave. Activate it from anywhere using a simple keyboard shortcut. Type a single prompt and watch it run simultaneously across multiple selected LLMs, then compare the outputs side by side. Build and save custom prompts in the prompt library, or browse community-submitted prompts for inspiration. Use the dedicated tools panel to generate images, translate text, or summarize the webpage you're currently viewing.
