Suno, the AI music generation service, has announced new tools to watermark and fingerprint tracks made on its platform, limit downloads, and update community guidelines to prevent copycat songs. The changes come as the company faces numerous lawsuits from labels and artist bodies.
In a blog post, co-founder and CEO Mikey Shulman said the platform wants to promote original creation while enabling more people to make music with its AI tools. The company said it will use audio watermarking and fingerprinting to prevent misuse on other streaming platforms, though it did not specify whether it will adopt an existing system like Google's Synth ID or develop a new one.
Suno also signed an agreement with lyrics provider Musixmatch to use its Sentinal system for copyright detection. Shulman said the tools are designed to be durable and resistant to tampering, without affecting the listening experience, and are not intended to judge whether a song is good or sufficiently human.
The company plans to add a new download policy to bar mass distribution on streaming platforms, but declined to provide details. It has also updated its community guidelines to explicitly prohibit 'deceptive audio presented as real' and using a real person's voice or likeness without permission.
Suno, which raised $400 million in a Series D funding round in June, is fighting legal battles on several fronts. It is in a lawsuit with Universal Music Group and Sony Music Group, coordinated by the RIAA. Late last month, a German court ruled in favor of licensing agency GEMA, saying Suno was breaking copyright rules.
Separately, 404 Media reported a data breach in November 2025 that revealed the platform scraped YouTube, Deezer, and Genius to train its models. Have I Been Pwned said the breach affected 55 million users, and a class action lawsuit in Massachusetts alleges the company overlooked security measures to focus on profit.
