Neural search API specifically designed for AI applications, offering semantic search capabilities, structured data extraction, and high-quality web indexes optimized for agent workflows.
Exa revolutionizes how AI applications access web data through its neural search API that understands semantic meaning rather than just keyword matching. Unlike traditional search APIs that rely on keyword frequency and basic ranking algorithms, Exa's neural search engine finds content based on conceptual similarity and context, making it invaluable for AI agents that need to understand and reason about web information.
The platform offers dedicated high-quality web indexes for different domains including people, companies, code documentation, financial data, and news content. Each index is specifically optimized for accuracy and relevance within its domain. Exa's token-efficient content extraction uses intelligent highlighting to extract the most relevant excerpts from web pages, significantly reducing token consumption while maximizing context quality for Large Language Model applications.

Yes, Exa is good for search & discovery work. Users particularly appreciate neural/semantic search returns conceptually relevant results even when the query wording does not match the page text, which is well-suited to llm-generated queries. However, keep in mind index size and freshness are smaller than google or bing, so very long-tail or hyper-recent queries can underperform mainstream search apis.
