Deezer launches free AI music detector covering twenty streaming platforms
Deezer has released a free online tool that identifies tracks generated by artificial intelligence in playlists from twenty of the most widely used streaming platforms, including Spotify, Apple Music, YouTube Music and SoundCloud. Available in twenty-seven languages and open to anyone regardless of which streaming service they use, the detector requires no Deezer subscription to operate.
The tool works by having the user connect their streaming account, after which the detector scans their playlists for the specific artifacts that AI generation software leaves embedded in audio files. Deezer states the accuracy rate exceeds 99%. Results can be saved and shared. The underlying technology has been running internally on Deezer’s own platform for a year and a half — over the course of 2026, the system identified and tagged more than 13.4 million AI-generated tracks.
The numbers surrounding the launch underscore the scale of what the tool is up against. In April, Deezer disclosed that 44% of the music uploaded to its platform daily is now AI-generated, amounting to roughly 75,000 tracks per day. In January 2025, that figure stood at around 10%; by September of the same year it had climbed to 28%. Of those synthetic uploads, up to 85% of their streams were classified as fraudulent — a pattern in which AI-created content is used to manipulate recommendation algorithms and divert royalties away from human artists. A joint survey by Deezer and Ipsos across eight countries found that 80% of listeners believe AI music should be clearly labelled, and 73% want that label to appear directly on streaming platforms. Deezer’s own internal data shows that 43% of users who migrated from other streaming services already had AI-generated songs in their playlists.
Deezer CEO Alexis Lanternier explained the decision to make the detector publicly available by pointing to the lack of action from competitors: “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.” The technology had already found commercial traction before the public launch: in January 2026, Deezer licensed it to Sacem, the French royalty collection society representing over 300,000 music creators and publishers. Meanwhile, Spotify has moved in a different direction, signing an agreement with Universal Music that allows Premium subscribers to create remixes and cover versions using AI tools.
The detector is available free of charge on Deezer’s official website.
