## Definition

ChatGPT is OpenAI's conversational AI assistant — one of the primary AI search surfaces where brands can be cited, recommended, or discussed. It combines a large language model with optional real-time web retrieval, producing responses that draw from both training data and indexed web content.

## Why It Matters for AI Search

ChatGPT is one of the highest-traffic AI search destinations. A brand's representation in ChatGPT responses is shaped by both its training corpus presence and its retrievability via web search. Brands that appear accurately and frequently in ChatGPT responses for relevant queries have strong AI citation presence on the platform with the broadest consumer reach.
