Deezer Launches Free Tool to Detect AI-Generated Music Across Streaming Platforms
When you hit play, you may wonder whether the track you’re listening to was composed by a human hand or a machine. Deezer’s new online detector promises to answer that question. The French music‑streaming service has rolled out a free, multilingual tool that scans playlists for songs created with artificial intelligence (AI). Supporting 27 languages and 20 major streaming platforms—including Spotify, Apple Music, YouTube Music and SoundCloud—the system claims to identify AI‑generated music with more than 99 % accuracy.
The detector works by examining a playlist that a user selects from a supported streaming service. Deezer’s algorithm hunts for subtle artifacts that AI music‑generation software tends to leave behind, such as specific rhythmic, harmonic or timbral patterns that differ from human‑composed pieces. When a track is flagged, the tool labels it as synthetic, allowing listeners to see which songs in their collection were produced by AI.
The launch follows a rapid rise in AI‑generated tracks on the platform. According to Deezer’s own data, 44 % of all new tracks uploaded to the service last month were created with AI—roughly 75 000 synthetic songs per day. That figure represents a sharp increase from 28 % in September of the previous year and from 10 % in January. The company also reported that 97 % of people surveyed in November 2025 could not distinguish between real and AI music.
User research conducted by Deezer shows that 43 % of listeners who migrated to the service from other platforms already had AI tracks in their playlists. In addition, 80 % of users expressed a desire for AI‑generated tracks to be clearly labeled. CEO Alexis Lanternier said the detector “provides transparency for listeners worldwide and is a tool that can be used by anyone, regardless of the streaming service they use.” He added that the company has been “at the forefront of transparency in music streaming” and that no other service has yet offered a comparable solution.
The release comes amid broader industry developments. Last month, Spotify and Universal Music Group announced a licensing agreement that will let Premium subscribers generate AI covers and remixes of licensed songs, a move intended to give fans new creative options while ensuring that artists receive royalties for derivative works. Regulatory attention to AI‑generated content has also increased. Pope Leo XIV has called for stricter regulation of AI technologies, urging developers to prioritize the common good. In the entertainment sector, filmmaker Martin Scorsese has faced criticism for advising an AI product that assists in storyboarding. Meanwhile, artists such as Backrooms director Kane Parsons and musician Jack Antonoff have publicly expressed concerns about the cultural impact of AI music.
Deezer’s detector could influence how streaming services handle synthetic content. By identifying AI‑generated tracks, the tool may help platforms enforce royalty rules, prevent fraud and give listeners the choice to avoid or seek out synthetic music. The company has made the detector available to other streaming services, though it is unclear whether competitors will adopt it.
At present, the tool is free for all users and does not require a subscription. Deezer has not announced any plans to monetize the service, and it remains to be seen how the broader industry will respond. The company’s next steps may involve expanding the detector’s capabilities, integrating it with playlist recommendation engines, or collaborating with regulators to establish labeling standards.
The launch marks a significant step toward greater transparency in the rapidly evolving landscape of AI‑generated music. As the proportion of synthetic tracks continues to rise, tools like Deezer’s detector will likely become an important resource for listeners, artists and industry stakeholders alike.
