“The only AI assistant we trust not to hallucinate. We’ve tried them all.”

Shaun Struwig
Documentation Engineering Manager
“Other vendors scored around 60% on accuracy. Kapa was over 99%.”

Andy Vayo
Head Enterprise Support
“Kapa knows when it doesn’t know. Nothing else came close.”

Alex Garnett
Developer Relations
“We ran two vendors side by side and let real questions decide. Kapa performed better on accuracy.”

Harness
“When it isn’t confident, it says so rather than inventing an answer. For a developer audience that’s exactly the behavior you want.”

Richard B.
Senior Developer Relations Engineer, Harness
“Our audience includes developers and less-technical users, so accuracy matters enormously. Kapa answers from our own documentation and cites it.”

“I was concerned about similarly named chip series, ESP32 vs ESP32-S3 vs ESP32-C3. It turned out not to be an issue.”

Frequently asked questions
What is Kapa?
−
Kapa is an ingestion and retrieval system for your unstructured knowledge. Ingestion assembles a unified knowledge base from 20+ types of sources, including documentation sites, PDFs, tickets, community threads and API specifications, and keeps it up to date as that content changes. Agentic retrieval searches across it to find what the agent needs, the moment it needs it. 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.
