Deezer's new tool scans rival playlists for AI music

If you suspect your daily mixes have been infiltrated by synthetic soundscapes, Deezer is ready to name names—and it doesn't care if you listen on Spotify or Apple Music.

On Thursday, the French streaming platform launched a free online AI music detector. Instead of keeping the tool locked inside its own ecosystem, Deezer opened it up to scan playlists across 20 competing services, including Spotify, Apple Music, SoundCloud, and YouTube Music.

If rivals won't buy the tech, give it away

The setup is dead simple. Users head to Deezer’s detector site, pick their current streaming platform, and grant account access. The tool pulls in playlists—seemingly utilizing Tune My Music, the same utility Deezer uses to onboard switchers—and scans the tracks for synthetic generation. If it flags anything, you get an alert and a ready-made option to share the breakdown on social media. The tool currently supports 27 languages.

Deezer isn't hiding the petty brilliance behind this move. The company spent the last year and a half aggressively tagging and scrubbing AI tracks from editorial recommendations. It even tried to license its proprietary detection algorithms to rival platforms. Nobody bought it. Qobuz built its own system, while streaming heavyweights like Spotify and Apple Music leaned into voluntary self-tagging honor systems.

Since no competitors wanted to pay up, CEO Alexis Lanternier decided to bypass corporate boardrooms entirely and drop the tool straight into users' hands.

Millions of tracks, almost entirely fraud

The floodgates Deezer describes are frankly terrifying. The streamer recently revealed that a staggering 44% of all new music uploaded to its library is synthetic.

That translates to nearly 75,000 AI-generated tracks every single day, topping two million per month. Yet despite the tsunami of content, real humans barely stream any of it. AI tracks represent just 1% to 3% of total listening on Deezer, and roughly 85% of those streams are flagged as artificial fraud and demonetized.

Basically, the platform isn't dealing with creative musical experiments; it's fighting automated farming operations gaming royalty pools. Deezer noted it's now weighing even stricter supplier rules, potentially following Bandcamp, which banned AI music outright earlier this year.

Why it matters

For everyday listeners, this is an entertaining and genuinely useful privacy check. We've all felt the eerie blandness of generic background filler slipping into algorithmic feeds, and running a quick scan gives users a rare peek behind the curtain without costing a dime.

For the music business, it is a masterclass in guerrilla marketing. Spotify and Apple Music have taken a hands-off, voluntary-disclosure approach to AI tracks, which largely avoids alienating tech partners but leaves catalogs vulnerable to slop. By handing consumers a free audit tool, Deezer effectively weaponizes transparency, turning rival libraries into potential PR liabilities.

There are real operational risks, of course. Automated detection algorithms notoriously produce false positives, and mislabeling an avant-garde human artist as an algorithm could trigger severe backlash. Still, Deezer successfully shifted the conversation from internal streaming politics into the court of public opinion.
