The Free plan allows paraphrasing up to 100 words in two modes, with basic grammar and summaries plus limited access to humanizing and the AI Detector. The Premium comparison lists paraphrasing in 23 languages and translation into more than 40 languages. QuillBot offers desktop and mobile apps for macOS, Windows, Android, and iOS, alongside Chrome, Edge, and Safari extensions. Its desktop app can appear as a widget in apps including Slack, Notes, and Messages; Premium also lists a Word add-in. QuillBot says one subscription works across its apps and platforms, with Premium usable on up to 10 devices at a time.
