Exa is a modern AI search engine with SERP API, website crawler tools, and deep research API. Power your app with web search AI and web crawling API.
Our vision

The next generation of search

Dear curious internet wanderer,

Welcome to Exa. Exa is an applied AI lab building a perfect search engine unlike the world has ever seen.

We spent years building massive-scale indexes and researching new retrieval systems for the agentic world we knew would arrive. That world has now arrived.

Today, Exa is the highest quality search API at every latency. We power search for Cursor, Cognition, HubSpot, OpenRouter, Monday.com and over 400,000 developers.

In the next few years the number of searches from AI agents will be 1000x more than Google searches today. Before us lies an opportunity to reinvent how the world gets information.

Information is critical civilizational infrastructure for our new AI reality. Politics is fragmenting, wars are raging, and AI is accelerating — we need tools we can trust that deeply inform us what's going on. If we can achieve perfect search so that every AI has the highest quality information, then every human will too.
