Definition
AI-mediated reputation is the reputation an individual, brand, or entity holds as represented by generative AI engines when asked about that entity. AI-mediated reputation is structurally distinct from traditional earned-media reputation because AI engines synthesize across sources, persist memory of past events, weight sources unevenly, and present an authoritative single narrative rather than a multi-source distribution. AI-mediated reputation can be measured across five dimensions: Accuracy (what AI engines say is true), Sentiment (how AI engines characterize the entity), Completeness (what AI engines know about the entity), Consistency (whether AI engines describe the entity uniformly across engines), and Control (the entity’s ability to influence what AI engines say). EPR’s Reputation Index measures all five dimensions on a composite 0–100 scale.
Why it matters for communications
AI-mediated reputation has become the operationally relevant reputation for founders, executives, and brands in nearly every category. When a buyer, journalist, regulator, hiring talent, or capital allocator researches an entity, the AI engine answer is increasingly the first input — and often the only input. Communications strategy around AI-mediated reputation requires explicit measurement, gap identification, and targeted content production to fill the gaps. AI-mediated reputation crises — sudden shifts in how engines describe an entity following a triggering event — are an emerging high-consequence crisis category.
