It's built for enhancing LLMs by providing relevant web content and minimizing hallucinations. The company offers flexible pricing, with pay-as-you-go options for individuals and small teams, and custom plans for high-volume needs.

FAQs
What is Exa?
Exa is a new search engine offering both proprietary neural search and industry-standard keyword search. It excels in finding precise web content, retrieving clean/rich web content, and can even identify similar pages based on input URLs. These technologies make Exa ideal for enhancing RAG pipelines, automating research, and creating niche datasets.
What's different about Exa's Neural Search?
We use a transformer-based model to understand your query and return the most relevant links. Exa has embedded large portions of the web so you can make extremely specific and complex queries, and get only the highest quality results.
How is Neural Search different from Google?
Google search is mostly keyword-based, matching query words to webpage words. In contrast, Exa's neural search understands meaning, returning actual company URLs. Additionally, Exa's results are not influenced by SEO, unlike Google/other engines.
How is Exa different from LLMs?
Exa is a new search engine built from the ground up. LLMs are models built to predict the next piece of text. Exa predicts specific links on the web given their relevance to a query. Exa connects these intelligences to the web.
How can Exa be used in an LLM?
Exa enhances LLMs by supplying high-quality, relevant web content, minimizing hallucination and outdated responses. An LLM can take a user's query, use Exa to find pertinent web content, and generate answers based on reliable, up-to-date information.
How does Exa compare to other search APIs?
Exa.ai offers unique capabilities: Neural Search Technology, Natural Language Queries, Instant Content Retrieval, Large-scale Searches, Content Highlights, Optimized for AI Applications, Auto Search.
How often is the index updated?
We update our index every two minutes, and are constantly adding batches of new links. We target the highest quality web pages.
How does similarity search work?
When you search using a URL, Exa crawls the URL, parses the main content from the HTML, and searches the index with that parsed content. The model chooses webpages which it predicts are talked about in similar ways to the prompt URL.
What security measures does Exa take?
We have robust policies and everything we do is either in standard cloud services, or built in house. In addition to this, we can offer unique security arrangements like zero data retention as part of a custom enterprise agreement.
What's our roadmap?
Support arbitrarily complex queries, Build a (much) larger index, Solve search.
