Frequently Asked Questions

QuillBot was created as a full-sentence thesaurus to help students and professionals write faster and with more confidence. Our users have found many creative ways to utilize our product, preparing doctoral theses, crafting legal emails, and document translation among others!

QuillBot was not designed for plagiarism and we do not support the use of the product for plagiarising. You should always cite the work you use and follow best practices as recommended by your institution or employer. Do not plagiarise using QuillBot.

QuillBot uses machine learning to understand and improve on the paraphrases it makes, and like a human, it can occasionally make mistakes based on the training data and human input we had it learn from.

Common Causes of Errors

There are a few mistakes that can consistently cause errors in paraphrasing:

• No space after a period: If you end a sentence with a period, but do not put a space between the period and the first word of the next sentence, our model will assume it is a single sentence.
• Mixing English and non-English letters: If you have a sentence that incorporates non-English letters being used as English letters (such as letters from the Cyrillic alphabet) you will receive errors in your paraphrasing.
• Line breaks: If you have a line break in the middle of a sentence, our model will treat it as two separate sentences instead of one, which will alter the meaning.

We are constantly training our AI to help reduce the mistakes QuillBot can make while also ensuring that the results you get read well and feel natural. If an error is showing up regularly, please contact us so we can investigate.

Modes are a setting that modifies what the QuillBot AI will focus on when you paraphrase something. Each mode has specific things it focuses on in your text.

There are seven modes total:

• Standard Mode: Standard mode is the default mode. This mode balances the changes it makes to your text with keeping the meaning intact and making it sound as natural as possible.
• Fluency Mode: This AI mode focuses on making your text sound as natural and grammatically correct as possible. This means that it will make the least amount of changes to your text, but will preserve the original meaning the best. Note that selecting this mode will also put the Word Flipper onto the lowest possible setting.
• Creative Mode: The Creative mode AI focuses on changing as much as possible in your input text. However, this can result in the meaning or overall coherency of the results being altered. This mode can be useful if you want to see something very different from your original text.
• Creative+ Mode: This mode uses an improved version of the Creative Mode AI that makes more intuitive changes and better understands certain things in language, such as common phrases or sayings.
• Formal Mode: Formal mode alters your text so it sounds more appropriate for a formal audience. This mode is good if you are writing in an academic or business context.
• Shorten Mode: This mode tries to shorten your text as much as possible while retaining the meaning in it. Shorten mode is very useful if you are seeking to lower the word count or overall size of your text.
• Expand Mode: Expand mode will try to increase the length of your text by adding more words when possible. This mode is helpful if you want to have a higher overall word count.

Free users can access Standard, Fluency, and Creative mode. Creative+, Shorten, Expand, and Formal modes are only available with a premium subscription.

The Word Flipper is a tool that modifies the number of words replaced by synonyms in your paraphrasing results. You can choose to replace more or fewer words by adjusting the corresponding slider. Do note that a more aggressive word flipper setting can affect the accuracy of a sentence.

There are two types of QuillBot accounts:

• Free account: A free account is one created by a user, which is free to use. These have access to three modes, three word flipper settings, and may paraphrase up to 700 characters at once. They may also summarize 5,000 characters at once and use our available extensions.
• Premium account: A premium account is an account that has a paid subscription associated with it. These accounts get the same features as free users, as well as additional features only available to premium users.

The benefits premium account users get include:

• Increased character limit: Premium accounts may paraphrase up to 10,000 characters at once, and summarize up to 25,000 characters at once.
• Four additional modes: Creative+, Shorten, Expand, and Formal modes are unlocked with a premium account.
• The highest Word Flipper setting: The highest setting lets you replace the most words possible using the Word Flipper
• Faster processing: Premium accounts have their text paraphrased faster.
• Compare Modes: This feature allows you to see a single sentence in multiple modes at once to compare results.
• Freeze Words: The ability to prevent the paraphraser from changing certain words or phrases.
• Show longest unchanged words: This allows you to see the longest section of your text that remains the same as the original after paraphrasing.

Teachers expect students to practice integrity and academic honesty, and so does QuillBot. Teachers want students to form original and authentic ideas, and they expect students, especially those in college or university, to write their own work and 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, such as MLA, APA, and the Chicago Manual of Style.

• 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

You can also read the QuillBot blog for more information and tips on writing successfully in your courses.

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 Windows 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.
