Deezer launches a free online tool that lets anyone scan their playlists across 20 streaming services to detect AI-generated music, after other platforms declined to license its detection technology.

What happened: Deezer, which was the first major streaming service to label AI-generated music, has released a free web-based detector. Users can visit Deezer's AI music detector site, select their streaming platform (Spotify, Apple Music, SoundCloud, YouTube Music, or 16 others), grant Deezer permission to access their account, and the tool will scan their playlists and flag any synthetic music it finds.

Why it matters: Deezer had previously offered to license its AI detection technology to other platforms, but no major competitor adopted it—Qobuz built its own system while Apple and Spotify chose a voluntary artist tagging approach instead. By releasing a free public tool, Deezer is making AI-music detection available to anyone concerned about synthetic tracks in their listening habits, regardless of which service they use.

What to watch: The tool works with 20 different platforms and uses the same underlying import technology (Tune My Music) that Deezer already employs when users switch from competitors. Users can share their detection results after scanning.
