Is QuillBot considered plagiarism?

Using QuillBot to paraphrase and cite sources is not plagiarism. However, paraphrasing someone else's work without attribution is plagiarism regardless of the tool used. QuillBot is a writing aid that should be used alongside proper citation practices, not as a way to disguise unoriginal work.

Which QuillBot mode is best?

Standard mode works for most general purposes. Fluency mode is best for fixing awkward phrasing while keeping meaning intact. Formal mode suits professional and academic contexts. Creative mode provides the most different rewrites but may need editing. Choose based on your audience and purpose.

Can QuillBot paraphrase entire essays?

Premium users can paraphrase unlimited text, processing it in chunks. However, paraphrasing an entire essay risks changing meaning in ways you might miss. It is better to paraphrase section by section, reviewing each output for accuracy and coherence before moving on.

Is QuillBot better than Grammarly?

They serve different primary purposes. QuillBot excels at paraphrasing and rewriting text. Grammarly excels at real-time editing and grammar correction across all platforms. Many users have both — Grammarly for everyday writing and QuillBot for when they specifically need to rephrase or restructure content.

What is QuillBot?

QuillBot is the leading AI paraphrasing tool, trusted by millions of students, writers, and professionals who need to rephrase, summarize, and improve existing text. The paraphraser offers multiple modes — Standard, Fluency, Formal, Simple, Creative, Expand, and Shorten — each producing distinctly different rewrites of the same input. This flexibility makes it useful for everything from academic papers to marketing copy to professional emails.

Beyond paraphrasing, QuillBot has grown into a comprehensive writing toolkit. The grammar checker corrects errors in real time. The summarizer condenses long documents into key points. The AI detector identifies AI-generated text, which is increasingly important for academic and publishing contexts. The citation generator helps students create properly formatted references in APA, MLA, Chicago, and other styles.

QuillBot's Chrome extension and Microsoft Word integration mean the paraphrasing tools are available wherever you write. The free plan includes the paraphraser with Standard and Fluency modes and a 125-word limit per paraphrase. Premium unlocks all modes, increases the word limit to unlimited, and adds the full summarizer and grammar checker. For the price point, QuillBot offers a practical set of writing tools that complement rather than compete with AI content generators.
