I've noticed when submitting peer reviews that some journals now have a box you have to check that pledges that you didn't use AI when doing the review. This seems dumb to me. I do use AI when I do peer reviews. I do the following:
1. Write my review as I always have,
2. Upload the paper to a frontier model and ask it to do a review as well. (I have settings set up so this data is not retained e.g. for training),
3. I compare the LLM review against mine, and I add to mine things that the LLM caught that I did not if such things exist.
I think this produces a strictly better peer review.
