We have a similar need.
We currently have two product areas, which are identifiable by URL. So we could create a chat bot for each, with knowledge base lookup.
Some articles apply to both products and some apply only to one product.
Limiting the bot to “Search specific categories” would solve a lot of headaches.
We could then have product specific categories and general categories.
Seems like a very small change for the product team @Snaedis , @goconnor ?
