AI Search — AI Glossary
Search systems augmenting or replacing keyword search with LLM-powered semantic understanding, synthesis, and conversational interfaces.
Overview
AI search (Perplexity, You.com, Bing AI, Google AI Overviews, Exa) generates natural-language answers from retrieved web pages rather than returning a ranked list of links. Combines web retrieval with LLM summarization. Challenges: source attribution, hallucination risk, and freshness. AI Overviews integrate into 40%+ of Google searches as of 2024.
