I added Azure’s QnA bot to the help section of my app, I updated all the help topics and added some pictures. It goes by keywords assigned to a topic but also I added the General Conversation ability through an upload. So you can talk to it as well.

It works really nice and I add a header to the page with some hints at what to ask the bot to get help on a particular topic which should help get people started.

I call it a spoon-fed AI as you need to set the trigger words or phrases to reply with a knowledge base article but it works really well.
