Deezer has built a free tool that will tell you how much of your music was made by a machine, even if you stream it somewhere else. The French service has opened its AI-music detector to the public, letting anyone scan their playlists on Spotify, Apple Music, and around 20 other platforms for AI-generated tracks.
By its own count, 43 per cent of people who switch to Deezer from a rival already have AI songs in their libraries.
It works like a quick audit. You go to Deezer’s detector page, connect your streaming account, let it scan your playlists, and see, or share, the results. The tool runs in 27 languages and is built on the detection technology Deezer has used in-house since early 2025, which can flag fully AI-generated tracks from the most prolific tools, Suno and Udio.
‘A vast majority of people want to know if AI music is being recommended to them,’ said chief executive Alexis Lanternier, who expects the tool to be ‘an eye-opening experience for listeners around the world’.

The figure underneath the tool is the eye-opener. Deezer says it now receives nearly 75,000 fully AI-generated tracks every day, more than 44 per cent of everything uploaded, and it tagged over 13.4 million of them across 2025. Yet the flood is far smaller in what people actually play: fully AI-generated music makes up just 1 to 3 per cent of streams.
That gap is the point.
Deezer says up to 85 per cent of the streams those AI tracks did pull last year were fraudulent, the work of bots and stream farms uploading synthetic music to siphon royalties, which is why it strips detected AI tracks from its recommendations and editorial playlists and discards fraudulent streams from artist payouts.
The free detector is also a competitive jab. By scanning rivals’ libraries, Deezer is casting itself as the transparency option in a market where Spotify has faced criticism over AI ‘artists’ and slop, and where viral episodes, such as the AI band that racked up streams before listeners realised it was not real, have unsettled fans.
Deezer was the first platform to tag AI music, in June 2025, and now licenses the detection tech to the rest of the industry. Its case is backed by a survey it commissioned from Ipsos: 80 per cent of 9,000 people across eight countries said fully AI-generated music should be clearly labelled, and 97 per cent could not tell an AI track from a human one in a blind test.
There are limits.
The tool catches tracks that are entirely AI-generated, not songs where AI was one instrument among many, and the headline figures are Deezer’s own. But the direction is hard to dispute, and the stakes are real: a CISAC study Deezer cites estimates that a quarter of creators’ income, as much as €4bn, could be at risk by 2028.
Music made by software is no longer a novelty on streaming services. The open question is whether listeners, once they can finally see it, will care.
