  AI-augmented search. Cited answers, consumer + Sonar API.

  Hybrid search engine that returns synthesized answers with inline citations rather than a list of links. Ships a consumer product and the Sonar API for adding cited search to your own apps and agents.

  AI insight: Its Sonar API exposes the same cited-search engine to your own app — so it's an answer product and a retrieval backend at once.

  Independent search index. Privacy-respecting, non-Google.

  API access to Brave's independently-crawled search index. Useful when you need a non-Google source, want to dodge upstream rate limits, or have privacy posture requirements that rule out scraping competitors.

  AI insight: One of the few search APIs backed by a genuinely independent crawl, not resold Bing or Google results.

  Neural search API. Find pages by meaning, not keywords.

  Semantic search engine that indexes the open web with embeddings — pass a description, get matching pages. Strong for research-style queries and find-similar workflows; formerly known as Metaphor.

  AI insight: Indexes the web by meaning, so 'find pages like this one' works as a query — formerly known as Metaphor.

  Search API built for AI agents. First-class in most agent frameworks.

  Search-as-a-tool for LLM agents — returns scrape-friendly results tuned for retrieval rather than ranking. Native integrations across LangChain, LangGraph, CrewAI, and the major agent surfaces.

  AI insight: Returns clean, scrape-ready content instead of a ranked link list — which is why it's the default search tool baked into agent frameworks.
