a combination of tools and a bit of brain power should lead to a decent estimation as to whether something's AI generated or not.

One thing that worries me is the combination of these tools with language translation web sites. I'm under the impression that translation web sites use the same sort of statistical/word-frequency analysis as LLMs. Not sure how the AI detection sites would react to a legitimate article after machine translation.

I tried taking an English article, using google translate to translate to German then Spanish then back to English, and passed that through the "GPT-2 Output Detector". The detector did alright with it, but I'm hoping to find time to run some more trials.
