Parag Agrawal’s newest project is trying to solve one of the messiest questions in AI: how to compensate content creators in a world where AI agents, instead of humans, are surfing the web.

The former Twitter CEO’s company, Parallel Web Systems, is launching Index, a platform that gives publishers, data providers, and independent creators visibility into how AI agents are using their content and a new way to be compensated for that use. Launch partners include publishers and distributors such as The Atlantic, Fortune, and PR Newswire; business and data intelligence providers including PitchBook, Enigma, RocketReach, and ZoomInfo; and independent creators including Alex Heath’s Sources, Packy McCormick’s Not Boring, and Mario Gabriele’s The Generalist

“The core thesis of the company was that agents will use the web a lot more than humans, and as a result of that, everything about the web will change, both the technology and the business models,” Agrawal told Fortune.

Rather than clicking around like human readers, AI agents can pull from dozens or hundreds of sources simultaneously to complete various tasks for users. Parallel already sells web access infrastructure to AI companies and developers, including Harvey, Notion, and Opendoor.
