Frequently Asked Questions

How does QuillBot's paraphrasing work?+
QuillBot uses advanced AI and machine learning to understand the context and meaning of your text. It then rewrites it using different words and sentence structures while preserving the original meaning. You can choose from 8 different modes (Standard, Fluency, Formal, Academic, Simple, Creative, Expand, Shorten) depending on your needs.
Is paraphrased content considered plagiarism?+
Paraphrased content is not plagiarism if done properly. You must still cite the original source even when using QuillBot to paraphrase. QuillBot helps you reword content in your own voice, but academic integrity requires citation of ideas and information from sources. Always run important work through QuillBot's plagiarism checker to ensure originality.
What's the difference between Free and Premium?+
Free allows 125 words per paraphrase, Standard mode only, 2 synonym options, and basic features. Premium offers unlimited words per paraphrase, all 8 modes, unlimited synonyms, plagiarism checker (20 pages/month), faster processing, and advanced grammar suggestions. Premium is $9.95/month and worth it for students and professionals.
Can QuillBot detect if I use it?+
QuillBot produces original text that differs from the source, so it won't be flagged as copied content by plagiarism detectors. However, AI detection tools may sometimes identify text as AI-generated. The key is to use QuillBot as a writing aid, not a replacement for your own work, and always review and edit the output to add your own insights.
Does QuillBot work in other languages?+
QuillBot currently works primarily with English text. While it can process text in other languages, the quality of paraphrasing is significantly lower. For best results, use QuillBot with English content. The team is working on expanding language support in future updates.
Can I use QuillBot for commercial purposes?+
Yes, QuillBot can be used for commercial content creation, marketing copy, and professional writing. Premium subscribers have full commercial usage rights. However, always review and edit the output to ensure accuracy, add value, and maintain your brand voice. Don't publish QuillBot content verbatim without reviewing.
