It's really nice to have something like this baked in. I can see this being handy if it's connected to external learning resources / sites to have a more focused area of search for it's answers. Having hard defined walls in the system prompt to prevent just asking for the answer seems pretty handy to me, particularly in a school setting.
Yeah, for sure. I wasn't asking from the framing of saying it's a bad idea, my thoughts were more driven by this seeming like something every other major player can just copy with very little effort because it's already kind of baked into the product.
