So email threads but on a web page, and filtered by subscription instead of senders/receivers. Clever.

How can I add this to my website?

How do you facilitate discovery? IE, what if I want to know about replies people have made without subscribing to their /social page?

It depends on the model. Deepseek-R1 says it supports tool use, but the system prompt template does not have the tool-include callouts. YMMV

docling might be a good way to go here. Or consider one of the existing full text search engines like Typesense.

What sort of monetization model would you like to see? What model would you deem acceptable?

For my projects that require a distinct unit of functionality, I typically reach for a JS library that I can include as a payload (no npm, no deps, just a JS file). SortableJS is a good example, so is MarkdownJS if I want the browser to handle MD rendering.

This only goes so far, though. At some point, an app developer might want to integrate these distinct units of functionality, and I'm not sure how I would go about that. I haven't gotten to that point.
