Pex

Pex is a digital rights technology company that builds automatic content identification (ACR) and Music Recognition Technology (MRT) used to identify recordings, compositions, and AI-generated music across the internet. Founded in 2014 with the stated mission of delivering a more transparent and equitable internet, Pex spent years refining its core identification technology until it could identify audio and video at scale. Its technology has been used to enable content identification on over 40 digital platforms, supplying data on social media usage and helping open up "black boxes" of unclaimed royalties. Pex's product suite centers on identification and data. Discovery lets users upload audio or video files or public URLs to find where content has been re-uploaded across major social platforms including YouTube, Facebook, Instagram, X, and TikTok, matching even heavily modified versions and short samples. The company also offers compliance search, AI song detection, and market-share reporting. Its identification registry contains more than 120 million recordings, including catalogs from Sony, Universal, and Warner. Pex serves several customer groups: platforms that need to identify music and manage copyright risk; music distributors checking catalogs before release; music publishers seeking new uses of their songs and market-share data; brands auditing social media and influencer content for unlicensed music; rightsholders seeking to reclaim control of altered or unauthorized content; and parties interested in detecting fully AI-generated songs. In 2025, Pex was acquired by Vobile, a global leader in digital content protection and transaction services founded in Silicon Valley with operations across North America, Asia, Australia, and Europe. Under Vobile, Pex continues to operate as a content identification and UGC data brand, with its MRT positioned for fraud prevention, commercial licensing, black box royalties, and AI song detection.

Pex was founded in 2014 with the mission to deliver a more transparent and equitable internet. According to the company's own account, it spent years refining and improving its core identification technology until it could identify audio and video better than anyone else. Combined with its search capacity, Pex enabled content identification on over 40 digital platforms, supplying never-before-seen data on social media giants and opening up black boxes of unclaimed royalties. Through its Digital Rights Management platform, Pex offered transparency to creators and rightsholders, allowing them to find all uses of their content online so they could increase revenues and prevent losses from digital copies. In 2019, regulatory changes created an opportunity for Pex technology to bring credit to all rightsholders on a global scale, and the company unveiled new offerings around that opportunity. Over the following years Pex expanded its product line to include Discovery for tracking uploads across social platforms, compliance search, market-share reporting, and AI song detection. Its identification registry grew to contain more than 120 million recordings, including catalogs from Sony, Universal, and Warner. In 2025, Pex was acquired by Vobile, a global leader in digital content protection and transaction services. Vobile was founded in Silicon Valley and has operations worldwide across North America, Asia, Australia, and Europe, serving entertainment companies, platforms, music labels, sports leagues, and publishers. Under Vobile, Pex continues to provide Music Recognition Technology for fraud prevention, commercial licensing, black box royalties, and AI song detection, and its technology powers real-time content identification and UGC data across the internet.
