What is Exa?
Exa is a neural search engine designed for developers and AI applications, providing a search API that retrieves semantically relevant results rather than keyword-matched pages.
Unlike traditional web search, which ranks content primarily by link signals and exact-match queries, Exa understands the meaning behind a search query and surfaces documents that match the conceptual intent even when the wording differs significantly.
The API is built for programmatic use cases: powering retrieval-augmented generation (RAG) pipelines, enabling AI agents to search the web in real time, and giving developers a clean interface to high-quality, up-to-date web content.
Exa supports both neural and keyword search modes and allows filtering by domain, date, and content type, making it flexible enough to serve a wide range of information retrieval scenarios.
Exa has become a popular choice for teams building LLM-powered applications that require access to current information beyond a model's training cutoff.
Its clean JSON responses, generous rate limits, and developer-friendly documentation make it straightforward to integrate into production AI workflows from research assistants and news aggregators to competitive intelligence tools and automated reporting systems.
