Exa is a web information organization tool designed for AI applications. It helps users quickly retrieve the information they need through semantic search, content extraction, and similarity search, avoiding information overload and inaccurate information. Exa's semantic search understands the semantic meaning of search terms, rather than just keyword matching, providing more precise search results. Additionally, Exa supports extracting complete and cleaned content from any webpage, as well as finding similar results via URL or long text. Exa also provides powerful filtering capabilities, allowing users to search based on domain name, date range, or data category. Exa's API supports programming languages such as Python, Javascript, and Curl, making it easy to integrate into existing systems.
