[Exa](https://exa.ai/) is an AI-powered search engine designed specifically for developers and researchers, providing highly relevant and up-to-date information from across the web. It combines advanced semantic search capabilities with AI understanding to deliver more accurate and contextually relevant results than traditional search engines.

With Exa, you can:

- **Search with natural language**: Find information using conversational queries and questions
- **Get precise results**: Receive highly relevant search results with semantic understanding
- **Access up-to-date information**: Retrieve current information from across the web
- **Find similar content**: Discover related resources based on content similarity
- **Extract webpage contents**: Retrieve and process the full text of web pages
- **Answer questions with citations**: Ask questions and receive direct answers with supporting sources
- **Perform research tasks**: Automate multi-step research workflows to gather, synthesize, and summarize information

In Sim, the Exa integration allows your agents to search the web for information, retrieve content from specific URLs, find similar resources, answer questions with citations, and conduct research tasks—all programmatically through API calls. This enables your agents to access real-time information from the internet, enhancing their ability to provide accurate, current, and relevant responses. The integration is particularly valuable for research tasks, information gathering, content discovery, and answering questions that require up-to-date information from across the web.
