QuillBot (quillbot.com) is one of the world's most widely used AI writing assistants, trusted by over 50 million users globally. Originally known for its paraphrasing tool, QuillBot has evolved into a comprehensive writing platform with 10 specialized paraphrasing modes, grammar checking, summarization, plagiarism detection, AI content detection, citation generation, and translation — all accessible through a single web interface and Chrome extension. QuillBot Flow integrates all tools into one unified word processor workspace.
How QuillBot Works
You paste text into QuillBot's editor and select from 10 paraphrasing modes — including Standard, Fluency, Formal, Academic, Simple, Creative, Expand, Shorten, Humanize, and Boomer Mode. QuillBot's AI analyzes context rather than just swapping synonyms, maintaining original meaning while improving clarity and style. The Grammar Checker runs simultaneously, flagging errors in color-coded categories. QuillBot Flow combines all tools into a single distraction-free workspace with Suggest Text and Flares for AI-assisted continuation.
