Deezer launched a public AI music detector on June 11, 2026 that scans playlists hosted on rival streaming services, including Spotify, Apple Music, SoundCloud, and YouTube Music. The tool is compatible with 20 different platforms in total and is free for any listener to use, regardless of whether they hold a Deezer subscription. The move follows roughly a year of failed attempts to license the underlying detection technology to competitors.
Deezer was the first major streaming service to label AI-generated tracks inside its own catalog, and it offered the same tech to peers shortly after. Qobuz declined and built its own detector. Apple Music and Spotify went a different route entirely, opting for voluntary tagging in which uploaders self-declare whether a track was made with generative AI — a system with obvious gaps when the incentive runs the other way.
With no licensees signed, Deezer is going around the platforms and straight to their users.
“No other company has followed our lead yet, so we decided to make it possible for everyone to check if their playlists include synthetic music, no matter which streaming platform they use.”— Alexis Lanternier, Deezer CEO
Key facts
- 01Deezer's AI music detector now works across 20 streaming platforms, including Spotify, Apple Music, SoundCloud, and YouTube Music.
- 02The tool launched June 11, 2026, after rivals declined to license Deezer's detection technology.
- 03Qobuz built its own detector; Apple and Spotify chose voluntary tagging instead.
- 04Playlist imports run through Tune My Music, the same service Deezer uses for library transfers.
- 05Users grant Deezer access to their account on a rival service, then receive a scan report they can share.
The workflow is straightforward. A listener visits Deezer's AI music detector site, picks their streaming service from the list of 20, and grants Deezer permission to read their account. Deezer imports the playlists — seemingly through Tune My Music, the third-party service it already uses to migrate libraries from competitors — runs them through its classifier, and returns a report flagging any tracks it identifies as synthetic. The results can be shared.
The competitive read is that Deezer has decided detection is a wedge product rather than a back-end license. Selling detection-as-a-service to Spotify or Apple Music would have meant ceding the relationship with the listener. Releasing it as a consumer-facing tool keeps Deezer's brand on every scan and turns a technical capability into a marketing channel — one aimed directly at users frustrated that their primary service won't tell them what's real.
It also raises the cost of doing nothing. Spotify and Apple Music can still point to their voluntary tagging policies, but listeners now have an independent second opinion that bypasses both. If Deezer's classifier flags a meaningful share of tracks on a Spotify playlist that Spotify itself never labeled, the gap becomes a story the larger services have to answer for.
The pressure on platforms to act on AI-generated music has been building. Warner Music Group acquired Sureel AI in recent weeks to track how generative models use its catalog, and Google is currently defending a musicians' lawsuit over training its Lyria model on YouTube uploads. The labels want attribution; the platforms want plausible deniability; the listeners, increasingly, want to know what they're paying for. Deezer is the first to give the third group a tool that doesn't depend on the first two cooperating.
How accurate the classifier is in practice will determine whether this lands as a credible utility or a marketing stunt. Deezer has not published a public false-positive or false-negative rate for the detector, and AI-music classifiers in general struggle with hybrid tracks where a human vocalist is paired with AI-generated instrumentals, or with traditionally produced songs that happen to share statistical features with synthetic ones. A high-profile mislabel of a human artist on a Spotify playlist would damage Deezer's credibility more than it damages Spotify's.
Still, the strategic logic is clean. Deezer is the smallest of the major Western streaming services by paid subscribers, and competing on catalog or price against Spotify and Apple Music is a losing game. Competing on a feature the larger players have actively chosen not to ship — and that a meaningful slice of musicians and listeners genuinely want — gives Deezer a reason to exist in the conversation. Whether the detector grows into a paid product, a labeling API the labels themselves pay for, or just a steady source of brand attention, it costs Deezer little to find out.
