Maybe I was just unlucky with the comment I tried it with (took the longest one I saw in my history), but I don't think I would have liked seeing it either removed or spat at for being considered as "AI generated"...
The detector also thinks this comment is fake. Seems influenced by flavors of mistakes.
Idiomatic ones. Spelling ones. Grammar. All non-native speakers will easily get flagged. Does not look spot-on for now. Checked all those assertion live-typing on the demo. 0.09% real.
