I've also hired people to write articles for my blog(s). Some of them are clearly AI-generated. Others are "maybe AI-Generated", or "probably AI-Generated with some editing". It is what it is, I guess. The web is changing.
Claude - The word "committee" contains 2 double letters - the double 't' and the double 'm'. Gemini - There are three double letters in "committee". They are the two "m"s and the two "t"s. ChatGPT - In the word "committee," there are 2 double letters: "mm" and "tt".
Meanwhile the double E cries in the corner...
I suspect that this stuff is AI-written. It could also be just really mediocre human writing, but I've really not noticed this particular quality of repetitive, drifting-off-topic writing until fairly recently.
Poor writing in freelanced work/low quality blogs often come from poor grammar and lack of continuity or smooth flow of thoughts. When written by AI, the grammar and spelling seem to be immaculate but the thoughts though linked well just go round and round.
