Licensing intermediary
ProRata
In short
ProRata sells attribution: it measures what share of an AI answer each source supplies, a basis for licensing, while saying that payment itself depends on the rights and agreements in place. Its Gist Answers engine falls back on a network of licensed titles that Gist puts above 1,600, and Gist GEO measures brand presence in AI search.

What ProRata does for this layer
From the vendor's own pages
ProRata Attribution breaks an AI answer into claims, matches each claim to supporting sources, calculates each source's proportion of the answer and shows it in an attribution bar. (prorata.ai) ProRata states that attribution does not pay rights holders by itself: "Payment depends on the relevant rights, licenses, and commercial agreements." (prorata.ai) ProRata was founded by Bill Gross, who is its CEO, and names its mission as protecting creativity in the era of generative AI through attribution infrastructure. (prorata.ai) ProRata lists Touring Capital, Mayfield, Prime Movers Lab, Idealab Studio, BOLD Capital Partners, DMG Media, Revolution and SBI Investment among its investors. (prorata.ai)
ProRata's second Gist product, Gist GEO, tracks and measures how brands appear in generative AI search. (prorata.ai)
Claims the vendor makes about itself
Gist Answers is an answer engine a publisher embeds on its own pages, drawing first on that publisher's content and then on a network Gist says holds more than 1,600 licensed titles from more than 150 publishing partners. (gist.ai) Gist states that all content in its network is licensed, that nothing is scraped, and that publisher content is never used to train AI models and can be removed at any time. (gist.ai) Gist names Woman's World, a McClatchy publication, as a publisher running Gist Answers. (gist.ai)
