Multi-LLM Hub is a Chrome extension designed to enhance productivity by allowing users to synchronize prompts across multiple AI models including ChatGPT, Gemini, Claude, DeepSeek, and Perplexity. This tool eliminates the need for repetitive copy-pasting by providing a unified interface to manage prompts and compare responses side-by-side. With features like a split-screen view and simultaneous multi-prompting, users can efficiently analyze the outputs of different AI systems in real time, making it ideal for developers, writers, and researchers who seek to evaluate the accuracy and creativity of AI responses.

The extension operates by letting users select their desired AI models and input a prompt, which is then sent to all selected models simultaneously. This functionality allows for a seamless workflow, ensuring that users can keep their best prompts organized and accessible. Privacy is prioritized as the extension does not store user prompts on its servers, maintaining a secure connection between the user and the AI providers. Multi-LLM Hub stands out for its efficiency and user-friendly design, making AI interactions more effective.
