description: kapa.ai is an AI assistant and answer platform that turns technical
  documentation, GitHub content, forums, and developer products into a retrieval-augmented
  chat experience. The kapa.ai Query API lets teams ask questions, run threaded
  conversations with streaming answers, perform semantic retrieval and search, and
  pull analytics over projects and threads via a REST interface authenticated with
  an X-API-KEY header.
