Deezer has licensed its AI detection technology to EJI, the Hungarian collecting society for performers' rights. EJI says the deal makes it the first collective management organisation in Hungary able to detect generative AI in published recordings, which matters because it does not pay royalties on recordings made with generative AI. Under the agreement EJI takes usage rights to Deezer's AI Detection product, which flags AI-generated recordings automatically.
The streaming service said in January it would sell the tool to the wider industry and brought it into its rebranded Deezer for Business unit in March. French society Sacem was already a customer. Deezer, which first deployed the detector in early 2025, says it remains the only streaming platform that actively finds and labels AI-generated music.
Its own figures explain the interest: in January Deezer was receiving about 60,000 fully AI tracks a day, roughly 39% of daily deliveries, and up to 85% of streams on them were judged fraudulent and removed from the royalty pool. Chief executive Alexis Lanternier said rights holders need protecting because music is a human creation, and that Deezer wants to offer the detector to the whole music business.
EJI director Pál Tomori welcomed the tool but said filtering is not enough on its own, and that AI training should need artists' consent and payment in the first place. The two organisations fought a court case in Hungary in 2016 and say they have since cooperated for nearly a decade. Deezer recently reported its first annual profit, €8.5 million for 2025.
