Our Take
Deezer is taking its detection tech direct-to-consumer because competitors rejected licensing deals, turning a failed B2B play into a free audit tool.
Why it matters
As AI-generated music floods streaming platforms, users have little visibility into what they're listening to. Spotify and Apple rely on voluntary artist tagging, which leaves gaps—Deezer's open tool fills that gap and quietly makes the case that voluntary labeling isn't enough.

Platform leads: audit your own detection claims against Deezer's tool this week so you know what your voluntary labeling is actually catching.
Deezer opens its AI detector to all platforms
Deezer launched a free web tool that scans playlists across 20 streaming services, including Spotify, Apple Music, SoundCloud, and YouTube Music, to flag AI-generated tracks. Users visit Deezer's detector site, select their streaming platform, grant permission, and receive a list of synthetic music in their library with the option to share results.
The tool uses Tune My Music, Deezer's existing import mechanism, to pull playlist data. The company built the underlying detection technology in-house and first began labeling AI music on its own platform. When Deezer offered to license the tech to competitors, it found no buyers. Qobuz built its own detector. Spotify and Apple opted for a voluntary artist tagging system instead.
"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," Deezer CEO Alexis Lanternier said in a press release.
Voluntary tagging leaves visibility gaps
The streaming industry's reliance on artist self-reporting creates a fundamental accuracy problem. Artists have no incentive to tag their own work as AI-generated if they believe it will hurt discoverability or credibility. Spotify and Apple have not published detection rates or error margins for their voluntary systems, leaving users without independent verification of coverage.
Deezer's move is a tacit admission that the industry's approach isn't working. By making detection available to users across platforms, the company sidesteps licensing negotiations and positions itself as the only major player offering cross-platform visibility. It also puts pressure on Spotify and Apple to either adopt detection or publicly defend why they won't.
Verify your own labeling claims
If you lead a streaming platform, music label, or rights management operation, test your detection or tagging claims against Deezer's tool on a sample of your catalog. Measure false negatives (AI tracks you're not catching) and false positives (human tracks flagged as synthetic). Use the results to calibrate public statements about AI music coverage. If you rely on voluntary labeling, document what percentage of your catalog is untagged and unverified.
