Deezer Launches Free AI Music Detector for Playlists on 20 Streaming Platforms

Deezer has released a free online tool that lets users scan playlists on major streaming services for AI‑generated music. The detector, announced on June 11 2026, supports 27 languages and works across 20 platforms, including Spotify, Apple Music, and YouTube Music.

The new service builds on technology that Deezer first deployed on its own platform in 2025. Users visit a dedicated page, connect the streaming service of their choice, and the tool analyses tracks for “specific artifacts” left by generative AI models such as Suno and Udio. According to the company, the detector achieves 99.8 % accuracy. Results identify tracks that are likely AI‑generated and can be shared by the user.

Deezer’s move follows a sharp rise in synthetic music on streaming services. The company reports receiving roughly 75 000 AI‑generated tracks daily, which represents more than 44 % of all new uploads to its catalog. While AI content accounts for only 1–3 % of total streams on Deezer, the volume of new synthetic tracks is growing rapidly. About 43 % of users who switch to Deezer from competitors already have AI‑generated songs in their saved playlists.

Listener studies released by Deezer show a strong demand for transparency. In blind tests, 97 % of listeners could not tell the difference between AI‑generated and human‑created tracks. Eighty percent of respondents said AI‑generated music should be clearly labeled, 73 % wanted platforms to indicate when AI music is being recommended, and 52 % believed AI tracks should not appear in the same charts as human‑made music.

Deezer has been the first streaming service to label AI‑generated tracks with an “AI” tag. The company also excludes such tracks from algorithmic recommendations and editorial playlists to protect human artists and prevent dilution of royalty pools. Up to 85 % of streams on identified AI tracks have been flagged as fraudulent and excluded from royalty calculations. Since January 2026, Deezer has licensed its detection technology to other industry players, including rights organizations such as Sacem.

In a statement, Deezer CEO Alexis Lanternier said the company’s leadership on AI transparency had led to the launch of the detector. He added that most listeners want to know when AI music is being recommended and that the tool would provide an “eye‑opening experience for listeners around the world.”

The broader industry context underscores the importance of such tools. A CISAC and PMP Strategy study estimates that up to 25 % of creators’ revenues could be at risk by 2028, potentially amounting to €4 billion globally. As generative AI tools become more sophisticated and accessible, the ability to identify synthetic content will be critical for maintaining trust between platforms, artists, and listeners.

Deezer has also applied for two patents related to detecting synthetic audio signatures, indicating a continued investment in the technology.

The free detector is now available to anyone with playlists on the supported platforms, offering a practical way for listeners to audit their music libraries and for the industry to move toward greater transparency in AI‑generated content.
