Brandon LazovicJanuary 10, 2021

Are you searching for a tool to either rewrite, paraphrase, or summarize existing content? 

Quillbot is an option that can help you save time reworking sentences and paragraphs as you churn out content. Read our review of Quillbot and the various features it offers. 

What Is Quillbot?

Quillbot is a paraphrasing tool that incorporates machine-learning AI to rewrite content to avoid Copyscape and plagiarism checks. 

This tool helps reword articles with ease and is trusted by millions of users worldwide. 

Different Quillbot Paraphrasing Modes

Below we’ll cover the different types of paraphrasing modes that Quillbot offers in its tool: 

Standard Mode

This input is a middle ground for changing the text you enter while trying to maintain the original meaning. Because of this, standard mode should be the most frequently used Quillbot mode. 

Fluency Mode

Fluency mode is most often used to fix grammatical mistakes and punctuation. Most changes are small and it won’t modify a lot of the original words/sentences you enter. 

Creative Mode

This mode will change your content the most, but is also more likely to make errors because it’s changing some much. 

Creative+  Mode

Creative+ mode takes Creative mode a step further and will change the original intent of your sentences even more than the other mode options. 

Formal Mode

The formal mode will change your content to come across as more formalized to better present yourself in a more sophisticated or professional way. 

Shorten Mode

If you’re looking to shorten up your content, the shorten option will try to convey the meaning of your content in the most concise or clear way. 

Expand Mode

Lastly, the expand mode will add more detail and depth to expand your sentence length. 

Summarizer Mode

Quillbot’s summarizer option is most often used for condensing articles/papers/documents into a short paragraph, grabbing the most important information while retaining the original context of the content. 

There are two summarization types: Key Sentence and Paragraph.

Key Sentence will show the most important sentences within the content, whereas paragraph mode combines elements of summarizing and paraphrasing to help explain key points within the text. 

This mode is helpful for summarizing news articles and research papers. You can either manually enter the text into Quillbot, or drag & drop a document into Quillbot, which it’ll summarize. 

Other Quillbot Options 

Now that we’ve covered the different modes you can use to rephrase your content in Quillbot, let’s dive into a few other features that the tool offers. 

Compare Modes

If you’re unsure which mode is the best for your rephrasing, you can use compare mode, which will show you side-by-side the types of changes that will occur between all of the modes in Quillbot. 

Word Flipper

If you want to change up your rephrasing, Quillbot allows you to set how much you want your words to be flipped. The tool can swap up your sentences and replace common words with synonyms to help avoid duplication. 

Note: the less words you ask Quillbot to flip, the more accurate it will be - the inverse is true, where if you ask Quillbot to flip a larger number of words, the results may become  less accurate. 

Freeze Words

Are there specific words that you don’t want changed? Quillbot allows you to specify what words should stay the same when rephrasing your content. 


Lastly, Quillbot provides statistics on your original content vs. what’s rephrased using its tool. It shows: 

  • Changes in the average words in a sentence
  • Changes in the average syllables in a word
  • Readability score changes (using the Flesch ease formula)
  • Sentence count differences
  • Word count differences
  • Percent of content changed
  • And Longest unchanged words

Free Version Of Quillbot Vs. Premium

While you can use Quillbot for free, there are benefits to using the premium version. 

In the free version, you can only rephrase or edit a few sentences at a time and you have a character cap for the amount of rephrases you perform. 

The premium version removes this cap and also allows you to rewrite larger blocks of text (up to 10,000 characters), as well as offers more modes that you can use to rephrase your content. 

Their annual subscription runs $80 per year and they offer a 3 day money back guarantee in case you aren’t satisfied with the premium version.

Should I Use Quillbot For Paraphrasing My Content?

Quillbot is a fantastic paraphrasing tool. I’ve tried a number of different ones and have found Quillbot to do the best at rephrasing content to make it unique and avoid plagiarism/duplication of existing content. 

Most content spinners or rephraser tools rely on simply changing out words with common synonyms, which can make your sentences read poorly or not make sense. 

Quillbot takes sentences and uses artificial intelligence to rewrite them for consistency and individuality.

Having said that, you’ll still need to perform some editing and ensure that your content is polished before uploading it to your website or crafting your article. 

It’s also best to only include a handful of paragraphs at a time, rather than entire articles, to ensure that the original intent is retained and that each sentence is rephrased naturally.
