Choose QuillBot if you want a broad set of writing tools across web, desktop, mobile, and browser extensions, or team administration through a Team Plan. The Free plan has a 100-word paraphrasing limit and only limited humanizing and AI Detector access, so those allowances may not suit heavier use.
