In text, to give a much better explanation, my idea is a generative AI that can create text tutorials for anything the scratcher asks (well, not anything, there are obviously limits like things that violate the scratch TOS, in which the user would be notified) Another cool feature if that happened would be a togglable "tutorial mode" for the editor, which shows you transparent blocks of blocks you should place.
Something important would be to make sure the generative AI isn't TOO powerful, because then scratchers could just put zero effort into possibly buggy projects. Another rule to enforce could be no featured projects that were created with generative AI.
