The features and benefits of QuillBot

An example of paraphrased text using Paraphraser. “Changed words”, “structural changes”, and “longest unchanged words” are highlighted.


Right off the bat, QuillBot offers a handful of user features:

  • Languages: French, Spanish, German, and more

  • 7 Modes: Standard, Fluency, Formal, Simple, Creative, Expand, and Shorten

  • Vocabulary slider: Slide for fewer (and more accurate) synonym changes or more (and less accurate) synonym changes

  • Integrations: Gmail, Chrome, Google Docs, Microsoft Word, Facebook, and LinkedIn

So QuillBot doesn’t only paraphrase text in English; it can also be used to translate and improve the fluency of text in multiple languages. As for QuillBot’s Paraphrasing modes, these give you a useful choice of paraphrasing styles. For example, Fluency mode cleans up grammar errors to make text more readable. Shorten mode cuts out the unnecessary “fluff” to simplify and streamline any piece of text, all with the help of AI and natural language processing.

Lastly, the vocabulary slider is a simple feature that lets you choose how many synonym changes it makes and how accurate or “random” those changes are. So QuillBot can also be used as an AI-powered thesaurus. Overall, the QuillBot tool offers a number of great features that can benefit different purposes, from trimming text for copywriting to expanding and cleaning up text for essay writing. We’re going to look at some features in a little more detail.

Citation generator

Students never forget how grueling it was to painstakingly add an accurate citation to every source they mentioned in their essays and research papers. It’s a seemingly simple task, but get it wrong and your grades can slip.

This is exactly what AI was made for. Taking over the repetitive and tedious tasks, so humans can focus on more creative endeavors. Well, Quillbot rose to the occasion with their citation tool. Simply enter the URL of the source you’re mentioning, select what type of source it is (book, website, image, ETC.), and then you’re good to go! This can turn an hour long job into a 10 minute task.

From what we can see, you can’t seem to select the citation style you want. This means a little bit of editing may be required to personalize it for your institution.

Plagiarism checker

Another invaluable tool for students is Quillbot’s plagiarism checker. In just seconds, this handy tool can scan huge amounts of text and detect whether anything is not credited where it should be. While you will have to upgrade to enjoy this feature, it’s definitely worth it.

It boasts 100% accuracy which is impressive for any AI app, and can execute these checks in over 100 languages. It’s worth using for those final checks before submitting essays or research papers as it will prevent missing out on easy marks, and can even prevent disqualification.

Grammar checker

While many AI tools offer grammar checks, they often come at a price. Quillbot’s free and simple interface means you can check sentences or big chunks of text for grammar mistakes. Not only will it highlight a mistake and provide a solution, it explains why it was wrong. This helps you develop your writing skills without even noticing.

Alongside the grammar checker, it also offers sentence structure suggestions. This will help improve the clarity of your writing and make it sound more fluent. So far, it seems this tool works in English, Spanish, French, and German. So, as well as helping native speakers improve their writing, it can also help those trying to learn a new language.

Different writing modes

We touched on it briefly, but this feature is worth exploring further. Unlike other tools, this valuable tool offers a list of different writing modes that suit nearly every need. This means whether you’re writing an essay, a novel, or even an email, you will be able to select the mode that most closely matches the tone of voice you’re trying to achieve.

As well as influencing the style, it will also determine how much it changes your writing. For example, the creative mode will change the most about your writing and may even change the meaning entirely. This means it can be a great option for breaking through writer’s block by generating new and interesting ideas.

Below is a full list of the different modes and a small description about what you can expect from them.


Interface and how to use QuillBot

QuillBot Paraphraser’s interface is quick and simple to use


Just looking at the user interface is enough to see that QuillBot is simple to use. The upper tabs let you select the different languages and modes as well as the paraphrasing accuracy (using the “Synonyms” slider). Then there are two text editors: one for the text you want to paraphrase and one for the paraphrased text that QuillBot will generate for you.

That’s really it. And using Quillbot boils down to four simple steps:

  1. Choose your desired language and mode

  2. Input text: You can type it in, paste it, or upload a document

  3. Click “Paraphrase”: The text will generate in the right-hand text editor

  4. Edit the paraphrased text (optional)

You can then edit the paraphrased text by manually typing in adjustments or clicking on key sentences, highlighted words, and sections – which include “changed words”, “structural changes”, and “longest unchanged words”. When you click on these, QuillBot will instantly provide further suggestions to choose from in a dropdown list.

What’s also worth mentioning is the Paraphrase Settings menu accessible on the right-hand side of the interface. Here you can choose to paraphrase quotations, include contractions, and use active voice. Overall, QuillBot Tool is simple to use with a text generation and editing process that’s quick and easy.

Is QuillBot good?

When you click on a word or phrase, Quillbot Paraphraser provides a dropdown list of synonym suggestions.


So how good is the paraphrased text QuillBot generates? Thanks to its versatile modes and diverse synonym suggestions, QuillBot does paraphrase text effectively. So there’s no doubt that it’s a useful AI tool that can be used for a wide range of purposes. Each mode generates paraphrased text to match the given setting.

And the dropdown synonym suggestions are largely good – despite a few unsuitable suggestions. Still, don’t forget that the quality of the generated vocabulary suggestions will depend on how “accurate” or “random” you set the Synonyms slider. So you may find the output settings will need tweaking at times. But QuillBot is good at paraphrasing text on the whole, no matter what text you feed it.
