What is Retrieval-Augmented Generation (RAG) Software for Claude Code?

Retrieval-Augmented Generation (RAG) tools are advanced AI systems that combine information retrieval with text generation to produce more accurate and contextually relevant outputs. These tools first retrieve relevant data from a vast corpus or database, and then use that information to generate responses or content, enhancing the accuracy and detail of the generated text. RAG tools are particularly useful in applications requiring up-to-date information or specialized knowledge, such as customer support, content creation, and research. By leveraging both retrieval and generation capabilities, RAG tools improve the quality of responses in tasks like question-answering and summarization. This approach bridges the gap between static knowledge bases and dynamic content generation, providing more reliable and context-aware results.

    Keenable

    Keenable is independent web search infrastructure for AI labs, inference platforms and agents. Crawler, index and ranking run in one stack, over 100B+ web documents updated in real time. The Search API gives agents two tools: search_web_pages finds pages, fetch_page_content returns a page as clean markdown. Both work through a REST API, an MCP server and a CLI on one API key. Latency is under 250ms p95 in US East. Search quality is tracked on NEEDLE, Keenable's public benchmark. It reruns daily, sends the same queries to several search providers and scores each against an oracle ranking built from their pooled results. For high-volume workloads, the Frontier Tier adds dedicated capacity, pricing from $1 per 1,000 requests at 100 RPS and above, and deployment in the cloud or on-premises. Time Machine, in early access, adds point-in-time search gated on Keenable's own crawl date: set query_time and both the corpus and the ranking rewind to that moment.
    Starting Price: $4 / 1000 requests
