From what I was thinking of bulding:

Packaging it up as a nice widget that can be embedded on your site easily.

So you just upload your docs and have a snippet of JavaScript for your website that gives you a help bot.

Hi, I took a quick look at trainmyai. I would say we are focused on this specific usecase. Making it easy for users to interact with help and support docs and knowledge. We will keep improving and getting better in this specific use case.

You get custom/fine-tuned models with Twig that only you have access to. You also get to train on private/behind-login information that is available to only your users.

Think of it as use-case-specific solutions vs generic solution.
