I get 0% (accurately) on my latest paper. Not super surprised, as I intentionally avoid some LLM-isms that I used to use because I don't want reviewers to have even the slightest indication that text is LLM-generated (even if in principle I'm not opposed to polishing or even wholesale generating academic text if it can convey the original research well, especially for non-native speakers).

I don't think the problem is as bad as a naive reading of this article suggests. I'm highly skeptical that anywhere near 65% of recent CS papers that I've read (mostly systems papers) are substantially AI-written. I threw some recent papers I've read into the system and they come back as 0-7%.
