Where does AI lose your writing voice first?

We’re launching Noren tomorrow, and I’m curious where this problem shows up most for people

When you use AI to write, where does it lose your voice first?

For me, it’s not grammar or clarity, but more structural. The draft is often clean, sometimes too clean, but the real problem is that it doesn’t build arguments the way I would or use the words I would normally use. When I write about problems, I tend to approach them diagnostically, probably because I trained as a doctor in a past life.

Curious if others see it more in email, LinkedIn posts, newsletters, fiction, founder updates, or somewhere else.
