AI Search
In one line
AI Search is the umbrella term for any search experience where an LLM writes the answer directly — covering AI Overviews, ChatGPT Search, Perplexity and the rest.
Going deeper
AI Search is the broadest label for the family of search experiences where an LLM writes the answer. It covers generative search, answer engines, AI Overviews, ChatGPT Search and similar surfaces — the same thing marketing decks mean when they say 'the AI Search era'.
In day-to-day work the term gets used at the KPI level: 'how does our brand show up across AI Search surfaces' is shorthand for measuring the whole family rather than one channel at a time.
Definitions are loose, though. Some sources include consumer chatbot answers, others restrict it to search-intent prompts. When you cite external benchmarks, check what the author actually folded under 'AI Search' first.
