Musixmatch has signed Suno as the first customer of Sentinel, its copyright detection service for AI and user-generated content platforms.
Suno has integrated the technology to identify when copyrighted compositions, lyrics, and music may be present, Musixmatch said on Thursday (August 6).
Sentinel monitors prompts and AI-generated output, detecting copyrighted lyrics at any stage of generation, according to the product’s website.
For Suno, Musixmatch says that Sentinel will provide “greater visibility into copyrighted material within user prompts,” informing the AI company’s own moderation, compliance, and product decisions.
A press release confirming the Suno partnership said that Sentinel “can rapidly identify durable matches with millisecond-level latency.”
Sentinel also maps user-generated content to rightsholders’ works through lyric matching, which enables detection of cover versions and royalty attribution.
Rio Caraeff, Co-President of Musixmatch, said: “Suno is enabling extraordinary new levels of creativity and expression, but the broader landscape calls for robust infrastructure to help platforms understand what is being created and whether copyrighted material is being submitted.”
“Sentinel was purpose-built to provide that visibility at the highest level of quality and hyper-scaler production readiness. We’re delighted that Suno is the first platform to adopt Sentinel, as part of their broader approach to responsible AI innovation,” added Caraeff.

Phil Castro, General Counsel of Suno, said: “As AI technology continues to evolve, building products responsibly is critical.”
“One of our guiding principles is to ensure our tools enable original music creation, not imitation, and Musixmatch has been a key partner in helping us identify and prevent misuse,” Castro added.
“Adding Sentinel will only strengthen our capabilities for protecting artists and human creativity, and is one of several measures we’re adopting to further support creatives while combatting fraud and abuse.”
Musixmatch says Sentinel returns decisions in under 100 milliseconds, integrates via API, and is built for EU AI Act and DMCA compliance.
The European Union‘s rules requiring AI-generated content to be labeled took effect on August 2.
Musixmatch says Sentinel draws on the world’s largest proprietary music database, trusted by more than 250,000 rights owners and music publishers across more than 250 languages.
The Sentinel deal lands on the same day that Suno published a blog post setting out its principles, in which CEO and co-founder Mikey Shulman wrote that the company has “never allowed prompts for specific artists or copyrighted songs.”
When a prompt names an artist, Shulman wrote, Suno strips the name out and redirects the request toward descriptive musical characteristics.
In addition, Shulman wrote: “We also work with Audible Magic, ACRCloud, and Musixmatch to screen uploaded audio files and lyrics for potential unauthorized use of artists’ work.”
Suno told MBW it disagreed with the ruling, which it said “rests on a fundamental mischaracterization” of how its technology works, and that it was weighing an appeal.
The company remains in copyright litigation with Universal Music Group and Sony Music Entertainment in a case coordinated by the RIAA, in which it argues that training on copyrighted works is fair use.
Warner Music Group settled its claim in November 2025 and entered a licensing partnership that included Suno‘s acquisition of Songkick.Music Business Worldwide
