What is Exa?
Exa is a web search engine designed from the ground up for AI agents and applications rather than human browsing.
It exposes a single API for search, crawling, and research, letting developers retrieve highly relevant web content, extract token-efficient highlights, and generate structured, citation-grounded answers that they can plug into their own AI products.
Exa emphasizes retrieval accuracy and speed, publishing benchmark results on demanding evaluations and offering configurations that range from quick lookups to deeper research passes.
It supports specialized verticals such as company search, people search, and code or documentation search, and its highlights feature can dramatically reduce token usage when feeding content to a language model.
Typical users are developers and companies building research assistants, RAG pipelines, enrichment workflows, and autonomous agents that need fresh, reliable web data with citations. Pros include high retrieval accuracy, low latency, token-efficient content extraction, grounded citations that reduce hallucination, and flexible search depth.
Cons include that it is API-first with no polished consumer search app, so non-developers cannot simply use it like a typical search website, and that production usage incurs metered costs that scale with volume.
Pricing follows a usage-based model with a free tier of credits for getting started and paid usage beyond that, scaling with the volume of queries and content retrieved.
For teams building serious AI products that depend on accurate, current web data, Exa is one of the most capable retrieval engines available. Pricing changes often, so check the official site for current plans.
