Exa is a neural search engine built specifically for AI applications that retrieves semantically relevant content from the web using meaning-based embeddings rather than keyword matching. Unlike traditional search APIs that return noisy results, Exa returns clean, structured data ideal for grounding LLMs with fresh, factual information. Developers building research agents, news aggregators, and RAG applications use Exa to get high-quality web data that dramatically improves the accuracy of AI-generated outputs.
