For Students & Educators

Teachers expect students to practice integrity and academic honesty, and so does QuillBot. Teachers want original and authentic ideas formed from the research you conduct and expect students, especially those in college or university, to cite their sources properly - distinguished professors have lost their job over this! QuillBot promotes the use of citations which credit the author and conform to the various accepted styles used by educators.

Essay Best Practices
  • Allocate time for research, writing and editing your work
  • Take good notes and follow your teacher’s note taking guidelines
  • Record original work URLs in your research to use for citations
  • Take the time to fully understand your paper’s concepts and main points
  • Use QuillBot to help paraphrase your own work
  • Cite all sources wherever they come from: traditional resource, a peer’s paper, QuillBot, and videos

QuillBot helps students with a variety of needs. QuillBot has you covered whether you want your students to expand their vocabulary, help streamline the writing process, or simply to demonstrate the variety and fluidity of language.

This is an error affecting users due to a Microsoft update. In our redesign, we were required to use a new API in Word due to Microsoft requirements. However, due to a Microsoft update, certain segments of users are unable to connect properly to our extension in Word. Our working theory is that users who are in one or more of these categories are being affected: • Non-subscription versions of Office for Windows. This means cracked/illegally obtained versions of Word, as well as Word instances that have not been activated with a product key. • Office running on versions of Windows 10 lower than 1903. • Versions of Office lower than 16.0.11629. If you are in one of these categories, please update your version of Office, Windows, or activate your copy of Word. Additionally, please ensure that you are logged into a Microsoft account when attempting to use the extension. If you are unable to do this, be aware we are working on a patch to assist these users.
