Yeah, this is a rare application of LLMs that kinda makes sense. It's essentially just rephrasing text based on statistics. That's what LLMs are good at, and it's pretty low stakes if it gets something wrong.

There's definitely an ick factor, considering all the problems with "AI", like exploiting labor and wasting energy. But this is exactly the sort of things LLMs can do well. Rephrasing things.

Would it be better to just get a human to do this? Yes. They already do with abridged versions and cliff notes. Best case scenario, this service is using LLMs to just make these people's jobs easier (doubtful, I know)
