The other similar site making the rounds, https://noslopgrenade.com/, is indeed in part written by AI as evaluated by Pangram.
Is that with or without the slop grenade examples included, because I can see how those might trigger the detector
I believe that one was discussed with the author on HN, and that they used AI to 'copyedit'. Unfortunately that's a trap because if you make a general copyediting request most LLMs will absolutely slopify your work-- and make edits that are unambiguously bad as well as just making it look like lazy llm output.
The better use is to ask it to point out grammatical and spelling errors, or phrasing which is unclear.. then go fix yourself (or direct highly targeted fixes that don't let it slopify). Never hand the clanker the pen for your writing unless you're looking to subject everyone to your Honest Take That Recontextualizes Everything.
AI detectors are useless. I don't know how this forum got so infected with Pangram shills, but at this point they need to be banned.
