Welcome to the Kapa documentation

If you are building agents, most of them need access to knowledge to do their job. Kapa is the agentic retrieval you build them on: it indexes your unstructured knowledge, documentation sites, PDFs, tickets, community threads, API specifications, and gives any agent the most relevant content from all of it, the moment it needs it. That goes for the agents you build into your product and workflows, and just as much for the ones your users already work in, like Claude Code or Codex.

Kapa is an ingestion and retrieval system. Ingestion assembles a unified knowledge base from 20+ types of sources and keeps it up to date as that content changes. Agentic retrieval searches across it to find what the agent needs. You hand Kapa to your agent as a search tool via MCP, or call it directly through the API. And for the cases where you do not want to build an agent at all, Kapa offers Prebuilt Agents for common use cases, out of the box.

Quickstarts

Index your first sourceStart here: connect your sources and let ingestion build the knowledge base

Connect an AI agent to your knowledgeHand an agent search over your knowledge as an MCP tool, in one API call

Explore by use case

These are common use cases that all rest on retrieving your knowledge. You can build any of them on Kapa's agentic retrieval, and for many of them a Prebuilt Agent ships the solution out of the box:

Knowledge for your in-product agentGive the agent inside your product access to your documentation, whatever framework it is built with

Ask AI on your documentationUsers answer their own questions, across evaluating, setup, and troubleshooting

Automate support with your knowledgeAnswer tickets automatically from your knowledge and reduce the human ticket load

Offer a public MCP serverLet your users' agents, from Claude Code to ChatGPT, search your knowledge through MCP

Build a company brainYour employees self-serve answers about your product, processes, and policies

Answer your community's questionsYour users get answers in Slack and Discord around the clock
