Exa

Editor's Pick

Neural search engine using embeddings-based next-link prediction — finds semantically similar content, not just keyword matches.

AI search APIs are the infrastructure layer that gives large language models access to current web information. Unlike traditional search engines, these APIs return semantically relevant, structured results optimized for retrieval-augmented generation (RAG) and AI agent workflows. They're essential for any AI product that needs to answer questions about the real world beyond its training data.

Editorial assessment

The most technically differentiated search API in the category. Embeddings-based retrieval surfaces results that keyword search misses entirely, which is why Cursor and AWS use it. At ~$10M ARR with 1,010% YoY growth and a $700M valuation, execution is strong — but pricing at $5-10/1K queries adds up fast for high-volume agent workloads.
