What is Exa?

Exa is a web search API built specifically for AI applications and LLMs. It provides neural search to find relevant web content, extracts clean webpage data, and delivers direct answers with citations to help developers build AI agents, RAG systems, and research tools. The platform serves AI developers, data scientists, researchers, and sales professionals who need reliable web data for their applications.

What sets Exa apart?

Exa sets itself apart with semantic search technology that understands the meaning behind queries rather than relying solely on keyword matching. This approach proves particularly beneficial for AI developers building applications that need to find contextually relevant content, such as research papers on specific topics or companies with particular business models. Exa's hybrid search architecture combines neural embeddings with traditional keyword search methods, delivering more accurate results for complex queries that would challenge conventional search APIs.
