I like kapa.ai for its easy integration, which simplifies the process by just adding a JavaScript code to our Hudi website. I also appreciate that we can search anything in the Hudi website or Hudi GitHub and ask for sample code or configurations. It significantly simplifies our development effort.

I find kapa.ai really helpful, especially for open source projects like Envoy (including Proxy, Gateway, and AI Gateway) where it's challenging to meet all user needs as usage grows. The pace of innovation at kapa.ai is amazing, from adding more information sources beyond docs to now including actual source code to the integrations in AI coding assistants, which is fantastic. The feature that provides statistical analysis of user questions helps identify missing features and clarify ambiguous ones, which unburdens the maintainer community. It's great that kapa.ai offers a safe space for people to ask questions, which can sometimes be intimidating in open source communities. The integration with platforms like Discord and Slack is cool because it helps people get assistance wherever they are, and it actually improves interactions within the community. The initial setup of kapa.ai was really easy and only took a few minutes.

Quality of answers, how much it leans on the actual documentation and other knowledge sources instead of what's baked into the LLM.
