What is UI Copilot?
UI Copilot is a Chrome extension that gives instant AI-powered design feedback on parts of any webpage. You select an area of the screen, and the tool analyzes it to return suggestions aimed at improving the UI.
It is built for quick feedback while browsing, so you do not need to leave the page or copy content into another tool. The workflow is simple: activate the extension, capture a region, and wait for the suggestions.
The extension focuses on practical UI/UX guidance such as layouts, color schemes, typography, and general design polish. It works on public websites, localhost, and development servers, which makes it useful for both live sites and work-in-progress builds.
UI Copilot is positioned for designers, developers, entrepreneurs, and anyone who wants a second opinion on interface quality. The website also emphasizes that it is a personal design assistant for the web and that it helps users learn design principles as they browse.
