Deezer on Thursday launched a free online AI music detector that lets users import playlists from about 20 major streaming platforms and scan them for AI‑generated tracks.
The tool works with roughly 20 services, including Spotify, Apple Music, SoundCloud and YouTube Music: visitors pick their streaming service on Deezer’s detector site, grant the company access, import playlists via Tune My Music and receive alerts when the scan finds synthetic tracks. Users can share the scan results.
Deezer released the detector amid internal data showing AI content is already pervasive on streaming feeds. The company says about 43% of users who switch to Deezer from competing services arrive with AI‑generated music in their playlists. Deezer reported receiving nearly 75,000 AI‑generated tracks per day and that synthetic work now makes up more than 44% of its new music delivery; earlier in 2025 the company said it was receiving about 60,000 such tracks daily. A separate Deezer‑Ipsos survey found 80% of respondents want AI‑generated music clearly labeled on streaming platforms.
The launch follows Deezer’s longer effort to police synthetic music on its own service: the company already labels AI‑generated songs internally and excludes them from algorithmic recommendations and editorial playlists. Deezer says it offered that detection technology to other platforms before building the consumer tool, and it signed a licensing agreement with the French royalty agency Sacem in January. The company also says it will offer its AI‑detection technology under license to the broader music industry.
Industry responses remain mixed. Qobuz has developed its own detection technology, while Apple and Spotify have adopted voluntary tagging systems rather than commercial licenses. Deezer frames the consumer detector as a stopgap because other companies did not take up its licensing offer; Alexis Lanternier, a company representative, said Deezer wanted to give people a way to check whether playlists include synthetic music on any streaming platform they use.
The timing is deliberate: Deezer has said the detector is an initial step to prevent synthetic tracks from significantly diluting the royalty pool. A 2024 Cisac study projected that 25% of artists’ revenue — roughly EUR4 billion ($4.6 billion) a year — could be at risk of being diverted by AI‑generated songs by 2028, a figure labels and rights organizations cite in arguing for clearer identification and royalty rules.
For users the process is simple but not invisible. Deezer’s site asks permission to access a chosen platform, pulls playlists via the Tune My Music import tool and runs its scan; results list tracks flagged as synthetic and can be shared. Deezer says the detector flags material in playlists from about 20 services, but the company has not published a public accuracy rate or a detailed list of the specific signals its scanner uses to classify a track as AI‑generated.
That gap is the story’s friction point: Deezer insists it pioneered AI labeling and offered the technology to peers but felt compelled to build a direct‑to‑user tool after others declined to license the system. The company’s move puts detection into listeners’ hands, but it also raises immediate questions that remain unanswered — chiefly which kinds of playlists and what proportion of flagged tracks the detector will reliably identify, and whether false positives or negatives will skew user trust.
Deezer says it will continue licensing its technology to platforms and rights organizations while watching adoption. For now the practical effect is clear: anyone worried about synthetic music in their library can run a scan; what is unresolved is whether that user‑level control will force a unified industry standard, prompt broader licensing of detection tech, or simply create parallel systems with different thresholds and outcomes. The detector is available now, and the next move that matters is whether other major services accept Deezer’s license or offer a shared alternative — until they do, listeners will be the primary arbiters of what counts as synthetic music in their playlists.
The push comes as music projects continue to experiment with new production tools, from mainstream releases to branded collaborations such as Ronaldinho unveils Tu Música debut CAMISA 10 with Sean Paul ahead of World Cup — — making the line between human and machine production a practical concern for fans and rights holders alike.
