Grammarly certainly comes to mind, for being essentially a free feature of most chat AIs now.

Interestingly this time around I could see the 'fire' affecting mid-large corporations (or at least some divisions of them) if they don't adapt. Adobe, being heavily focused on graphic design seems like it could be under pressure. Low-end consulting / outsourcing is largely doing the same work AI is good at. Similarly with technical gig-work (like Upwork).
