QuillBot

QuillBot is a writing toolkit built around rewriting and checking text. Its paraphraser restyles a passage in different modes, and the grammar checker, plagiarism checker, AI detector, and humanizer cover the quality and originality checks that usually follow. Around those core tools, QuillBot now bundles a summarizer, translator, citation generator, AI chat, and a set of creation tools for images, presentations, websites, and PDFs. Most tools work on a free tier with word limits, while the paid plan removes those limits and unlocks the full detector and humanizer features. A Chrome extension brings the writing assistant into other websites.
