Frequently Asked Questions
Is using QuillBot to rewrite my academic paper considered plagiarism?
Using QuillBot to improve the clarity, grammar, and flow of your own original writing is generally acceptable. However, copying someone else’s work and running it through a rephrasing engine to bypass detection checks breaches academic integrity rules at almost all universities.
What does the synonym slider setting control on QuillBot?
The synonym slider sets how much vocabulary variation the AI applies to your paragraphs. Moving the slider to the left keeps your original text structures more stable, while sliding it to the right inserts a higher volume of creative rewordings.
Can I integrate QuillBot directly into Google Docs?
Yes. QuillBot offers an official add-on module available via the Google Workspace Marketplace. Once installed, it opens a dedicated sidebar widget directly beside your active Google Doc sheet, allowing you to edit text while writing.
What is the word limit on QuillBot’s free text summarizer tool?
The free version of the QuillBot summarizer tool allows you to scan up to 1,200 words per individual input block. Upgrading to a premium subscription plan removes this cap, allowing you to process long-form text logs or full manuscript files.
Does QuillBot require an internet connection to process text?
Yes. QuillBot processes text inputs through advanced machine learning models hosted on its cloud servers. As a result, the application requires a live, stable web connection to analyze paragraphs and return rephrased content to your screen.
