Overview
Numbered markers inside an answer that preview their source on hover, plus the list of sources below it. It comes from the AI chat kit and also works on its own. Keyboard and screen readers: Each marker is a real link named "Source n: title, domain", so it reads well out of context. The preview opens on hover and on keyboard focus, and never holds content that the link name lacks. With reduced motion, extra sources and previews appear without movement. Built with React 19 and TypeScript, Tailwind CSS 4, Base UI, Lucide icons and Motion. Light and dark themes come from CSS variables you can edit, and every demo uses believable sample data you replace with your own. Included: the component source, its sample data, light and dark theme variables, a runnable demo page, and setup guides for people and for AI coding agents.
