Is There a Way to Label AI-Assisted Content?

I think labeling is a really good and positive thing because it gives people an idea of what to expect. It's tricky too because a lot of AI writing right now is hybrid human and AI kind of collaboration more than just purely AI-generated I think. At a micro level it becomes really difficult to say like well this part of it was written by AI this part was written by me so how do we do that technically as writers or within products that help us as writers that use AI? There's a lot of unanswered questions there that I'm interested in because I like tech products and I like to try to figure that out.
