How do I make AI-assisted product descriptions sound distinct across a large catalog?

I’m working on product descriptions for a catalog with hundreds of similar items. AI helps with the first draft, but the results often feel like the same paragraph with a few product details swapped out.

How do you keep product descriptions at scale specific and useful without manually rewriting every listing? I’m especially interested in approaches that preserve a consistent brand voice while making real differences—such as material, fit, or use case—clear to shoppers.
