AI search
AI search answers a query with generated text and cited links instead of a ranked list of pages, as Google's AI Overviews and AI Mode and Perplexity do. This page covers how those answers pick their sources, how they get gamed, what users can switch off, and the search APIs developers use to build their own.
- AI Overviews US rollout
- Announced May 14, 2024: "AI Overviews will begin rolling out to everyone in the U.S."
- Google's AI Overviews fixes
- May 30, 2024: Google traced a bad answer to satirical content, limited satire, humor and user-generated content in some answers, and added triggering restrictions
- Turning AI Overviews off
- Google calls them "a core Google Search feature" that "cannot be turned off"; the Web filter shows text links without them
- What site owners need
- "No additional requirements" to appear in AI Overviews or AI Mode; nosnippet, data-nosnippet, max-snippet and noindex limit what is shown (page last updated December 10, 2025)
- Perplexity citations
- "Each answer includes numbered citations linking to the original sources"
- Perplexity Search API price
- $5 per 1,000 requests; $1 per 1,000 with Fast Search
- Anthropic web search tool price
- $10 per 1,000 searches, plus token costs; citations always enabled
- Grounding with Google Search (Gemini API)
- 5,000 free search requests a month shared across Gemini 3 and newer models, then $14 per 1,000
