Exa

Exa (formerly known as Metaphor) offers an AI-powered search engine that can connect to the vast knowledge of the internet. Exa delivers highly relevant search results from a comprehensive database spanning companies, news, research papers, web content, and more. You can refine your search with a number of useful settings, including the option to filter specific website results.

Developers can easily integrate Exa’s capabilities into their AI apps and models through simple APIs and SDKs, which also includes the functionality to filter domains, specify timeframes, find similar websites, extract summaries, and even allow your AI to engage in open-ended conversations using the retrieved information.
