# ProRata > Review edition. This file is an informational summary, not a guarantee of AI-search visibility. Custom-domain launch and indexing are pending approval. ProRata builds the trust and transparency layer for generative AI. ProRata Attribution identifies discrete claims in an AI answer, verifies matching claims in the sources used to generate it, calculates the proportion provided by each source and creator, and displays an attribution bar as a nutrition label for the answer. Source attribution is not limited to licensed sources. Readers, organizations, and creators can understand the evidence behind AI output. Its three core audiences are Publishers & Creators (including rights holders), Enterprise Businesses, and Generative AI Platforms. ProRata is committed to consistent, transparent, auditable attribution that enables trust and a sustainable ecosystem.

It does not establish a legal payment entitlement. Audio, music, image, and multimodal capabilities are future development directions, not availability claims. Publisher A 61.6%, Publisher B 21.2%, Publisher C 5.1%, and other contributing sources 12.1% are one illustrative whole-answer example, not live data.
