About this extension
Louistify YouTube is a lightweight browser extension that adds random transparent Louis image overlays to YouTube thumbnails.
It works on YouTube pages and dynamically loaded thumbnails, including home feeds, search results, video sidebars, channel pages, and infinite scrolling.
The extension runs locally in the browser. It does not collect, store, sell, share, or transmit user data. All JavaScript, CSS, icons, and overlay images are bundled inside the extension package, and no remote code is used.
