# PeakMetrics > PeakMetrics is a narrative intelligence platform that shows communications, public affairs and risk teams how stories about their organization spread across news, social media and AI answers, and flags when those narratives are coordinated or manipulated. Its AI Perceptions product measures how ChatGPT, Claude, Gemini, Perplexity and Grok describe a brand, which is the practice usually called Generative Engine Optimization (GEO). The company's position is that press coverage and AI visibility are different things, and that comms teams need to measure both. PeakMetrics sells to communications, public-affairs, risk and government teams.
