QuillBot review

QuillBot is a focused toolkit for rewriting rather than drafting. The free plan paraphrases up to 125 words at a time in Standard and Fluency modes, fixes basic grammar, summarizes up to 1,200 words and gives limited access to the AI Detector and Humanizer. Premium removes the word cap, adds 9 built-in modes such as Academic and Simple plus unlimited custom modes, checks up to 25,000 words a month for plagiarism, and raises summaries to 6,000 words. QuillBot also generates citations and corrects grammar in 6 languages. It runs as browser extensions, a Word add-in, desktop apps and mobile keyboards, so it fits wherever students type. The main limitation is scope: it will not research or outline a paper the way ChatGPT or Gemini will. Our checker could only see the price in euros, so confirm the USD price on QuillBot's site. We compared documented features and published prices.
