Exa
Neural search API optimised for LLM retrieval — find content by meaning, not keywords.
Exa is a neural search API optimised for LLM retrieval — find content by meaning, not keywords. Uses neural embeddings to search by semantic meaning rather than keyword matching.
About Exa
Exa is a neural search API that finds content by semantic meaning rather than keyword matching.
Its distinguishing trait is that it targets LLM retrieval directly: the API is built for retrieval-augmented generation and LLM pipelines, and it adds content extraction and similarity search so results can be fed straight into a model.
It fits developers building RAG systems and LLM apps who want meaning-based retrieval. It is a poorer fit if you want a browser-style search box, since the primary interface is an API rather than a traditional search UI, and the free tier caps query volume and rate limits.
Among AI web apps in the search space, Exa sits on the developer/API side rather than the consumer-search-engine side.
