Show HN: Chrome extension that types one prompt into many AI chat tabs (chromewebstore.google.com)

A new Chrome extension, developed by ChatWithMultipleAI, enables users to input a single prompt and simultaneously receive responses from various AI chat models, including ChatGPT, Claude, Gemini, and DeepSeek. This innovative tool simplifies the process of comparing outputs by allowing users to view results side-by-side in tiled windows or grouped tabs, significantly improving their workflow and efficiency when testing different models. With functionalities like saving prompts as templates for future reuse and an intuitive keyboard-first interface, the extension eliminates common inefficiencies in multi-AI interactions. This tool is highly relevant for professionals and researchers who frequently engage with AI systems, providing a streamlined approach to validate model responses for tasks such as coding challenges, campaign development, and specification reviews. Importantly, the extension prioritizes user privacy by storing data locally within the browser, ensuring no data is collected or sold. It's a game-changer for those who rely on AI for comparative analysis, enabling deeper insights and faster decision-making without the hassle of manual copying or switching between tabs.
