About QuillBot

QuillBot is an AI paraphrasing and writing tool used primarily by students, researchers, and non-native English speakers who need to rewrite, refine, or summarise existing text. With more than 35 million monthly active users, it is one of the most widely used writing assistants focused specifically on reworking and improving prose. The paraphraser is the core feature. It rewrites a block of text using one of several modes: Standard, Fluency, Formal, Academic, Simple, Creative, and Shorten. Fluency mode corrects grammar while preserving the original meaning. Academic mode shifts vocabulary to suit scholarly writing, making QuillBot particularly useful for students adapting source material or researchers reworking technical content for different audiences. The Summariser condenses long documents, articles, or research papers into key points - useful for quickly extracting essential ideas from long-form content. The Grammar Checker and Chrome extension let users access QuillBot's features directly inside the tools where they already write. The free plan covers basic paraphrasing up to 125 words. Premium at $8.33 per month (billed annually) removes length limits, unlocks all paraphrase modes, and adds the full summariser.

QuillBot vs Grammarly →tie
Grammarly and QuillBot are the two most widely used AI writing improvement tools, but they solve different problems. Grammarly is primarily an editing assistant - it catches grammar, spelling, clarity, and tone issues in real time across every app you write in. QuillBot is primarily a rewriting and paraphrasing tool - it transforms existing text into new versions, which makes it more useful for repurposing content and avoiding repetition. Many writers use both: Grammarly for real-time editing while writing, QuillBot for reworking finished drafts.
