About Kapa AI

Kapa.ai is a platform that transforms technical documentation into intelligent, customer-facing AI assistants. It indexes content from a wide variety of sources—including documentation sites, GitHub repositories, Slack channels, PDFs, Zendesk help centers, YouTube videos, Notion pages, Confluence wikis, Discord forums, Q&A threads, and Stack Overflow—to build assistants that can answer complex technical questions with high accuracy. The platform emphasizes grounding every answer in the provided sources and is designed to say "I don't know" when it cannot confidently respond, which helps reduce hallucinations. It offers multiple deployment options such as embedding in documentation pages, support forms, or via API/SDK, making it suitable for both external customer support and internal knowledge bases. Kapa.ai is trusted by companies like n8n and OpenAI, and is rated highly on G2 (4.9/5 based on available information). The platform appears to offer a free trial, but exact pricing and free-tier limits should be verified on the official website.
