Quillbot paraphrases without context at the expense of meaning. Case in point: one of my students submitted an essay about George Orwell’s Beast Ranch… I can always pick out Quillbot writing because the sentences it generates are absurd – they sound fancy but the precision is wrong so they’re ultimately meaningless or silly.
