AI product read

Download, copy, or open high-resolution thumbnails and cover art from YouTube, SoundCloud, Spotify, and YouTube Music

Makes it easy to extract and save the full-resolution thumbnail/cover images from music and video streaming platforms, which otherwise don't provide a direct download option for cover art.

1. User installs extension and optionally configures grab method (Open/Download/Copy) and context menu items in the options page. 2. User navigates to a supported page (YouTube video, Spotify track/album, SoundCloud track, YouTube Music). 3. User triggers the extension via: clicking the extension icon, using a keyboard shortcut, or right-clicking and selecting a context menu item. 4. Extension detects the platform from the URL, extracts the thumbnail/cover image URL using platform-specific DOM selectors or known URL patterns. 5. Extension performs the configured action: opens the image in a popup overlay, downloads it as a file, or copies it to the clipboard (converting to PNG if needed).

Target users: Content creators who need thumbnails for references or thumbnails / Music enthusiasts who want to save album/track cover art / Designers and marketers collecting visual assets from media platforms / General users who want to quickly save video thumbnails or music covers

Content script relies on specific CSS selectors for Spotify and SoundCloud which may break when those platforms update their DOM structure.
Cannot confirm if oEmbed fallback works for all sites without live testing.
