Exa AI

Exa is an AI-native web search API that retrieves web content based on semantic similarity to a query rather than keyword matching — finding pages that express similar ideas to a question, not just pages containing specific words. Developers use it to build search experiences, research tools, and knowledge applications.

Developers building AI products that require high-quality web retrieval use Exa to access the web as a knowledge layer rather than a link list. The semantic retrieval approach is more useful for nuanced, conceptual queries than keyword-based search APIs.

Exa is primarily a developer product — it has no consumer interface for end users. Integration requires API access and development resources. Pricing is consumption-based and oriented toward production use. Researchers and developers building retrieval-augmented AI applications are the primary audience.
