Cogcopper von liksom

Cogcopper automatically finds vinyl record prices on Discogs when you watch music videos on YouTube. A price badge appears next to the video title showing the median price and a direct link to the Discogs marketplace listing. Click the toolbar icon to enable additional format lookups for Cassette and CD. Free, fast, and private. No data is collected. All processing happens locally in your browser.
