Deezer just handed everyone a way to find out how much AI-made music has crept into their playlists. The Deezer AI Music Detector, a free web tool launched on June 11, connects to your account on around 20 streaming services, including Spotify, Apple Music, and YouTube Music, and flags tracks generated by tools like Suno and Udio.
The process takes three steps. You open the detector page, connect a streaming account, and let Deezer scan your playlists. The results are shareable, and the tool works in 27 languages. Under the hood, it runs the same proprietary detection technology Deezer already uses on its own catalog.
Deezer has been tagging AI music since early 2025
The French streamer started labeling fully AI-generated tracks on its own platform about a year and a half ago, and so far no major rival has copied the approach. “By detecting and tagging AI generated music over the past year and a half, Deezer has been at the forefront of transparency in music streaming,” said CEO Alexis Lanternier.
The numbers explain why the company keeps pushing. Deezer says it now receives about 75,000 fully AI-generated tracks every day, which works out to 44 percent of all new uploads. In 2025 alone, it detected and tagged 13.4 million AI tracks. Although AI music drives only 1 to 3 percent of total streams, Deezer ties as much as 85 percent of those plays to fraudulent activity.
Listeners want labels, and most can’t spot the fakes
Deezer’s own research suggests the tool will surprise people. In a blind test, 97 percent of survey respondents could not tell AI-generated music from human-made tracks. Meanwhile, 80 percent agreed AI music should be labeled, 73 percent want those tags shown on streaming platforms, and 52 percent said AI songs should stay out of the main charts. The company also found that 43 percent of users who join Deezer from other platforms arrive with AI music already sitting in their playlists.
The detector lands in the middle of a broader fight over AI’s place in music. Streaming rivals have mostly leaned the other way, and Spotify is even building an AI covers tool with Universal Music rather than labeling synthetic tracks. For now, Deezer’s scanner is the only way for listeners on any major platform to see exactly what the machines have slipped into their rotation.
