What is AI search?
Quick answer
AI search is a way of finding information where an AI engine understands your question and generates a direct answer — often citing sources — instead of returning a list of links. ChatGPT, Google Gemini, Google AI Overviews, Perplexity and Microsoft Copilot are all forms of AI search.
What AI search means
AI search is the use of artificial intelligence — particularly large language models — to answer queries conversationally and directly. Rather than making you scan ten blue links, an AI search engine reads your question, retrieves relevant information, and composes a single answer, often with citations. It’s a fundamental change in how people find and choose things.
How does AI search work?
Most AI search combines two techniques: retrieval (finding relevant, current information from the web or a database) and generation (using a language model to compose an answer from it). This “retrieval-augmented generation” lets engines give up-to-date, sourced answers. The engine decides which sources to trust and cite — which is exactly what GEO and AEO aim to influence.
The main AI search engines
- ChatGPT (with search) — conversational answers with web citations.
- Google AI Overviews & AI Mode — AI answers at the top of Google results (AI Overviews guide, AI Mode guide).
- Google Gemini — Google’s conversational AI.
- Perplexity — an answer engine built around cited sources (Perplexity guide).
- Microsoft Copilot — AI search across Bing and Windows.
Why AI search matters for brands
As users get answers without clicking, being cited in the answer becomes the new visibility. Brands that aren’t mentioned by AI search engines lose reach even if they rank in classic search. That’s why measuring and improving AI search visibility is becoming essential.
