Copy YouTube Ad URL

Copy YouTube Ad URL is a Chrome extension that detects the video URL of a YouTube ad while it is playing, saves it locally, and lets you copy it later from a simple popup. When a YouTube ad is played, the extension detects the ad video URL and stores it in local browser storage. Open the extension popup to review detected ad URLs, ad titles, and detection times. Each history item has a copy button that copies the URL in the `https://www.youtube.com/watch?v=...` format. Key features: - Automatically detects YouTube ad video URLs while ads are playing - Saves up to 100 detected ad URLs locally - Shows a badge when an ad URL is detected - Displays URL history, titles, and detection times in the popup - Shows the currently playing ad URL at the top of the popup - Copies ad URLs to the clipboard with one click - Clears local history when needed - Supports light, dark, and system themes - Supports Japanese and English UI text This extension is useful when you need to record, review, or share YouTube video ad URLs for ad research, creative checks, or reference. Detected ad URLs, ad titles, and theme preferences are stored in local browser storage. The extension does not send this data to the developer's server, does not use external analytics services, and does not collect personal information.
