Do You Even Need an Article Rewriter Tools like Quillbot/Spinbot?

Article rewriters are often used to explain facts in different tones with improved vocabulary.

Maybe you have a dull tone in your writing and want to add some depth of flavor to it. This is precisely why article rewriters exist.

As we all know, English and other languages are vital tools for communicating important facts and ideas to others. Speaking and writing the English language are two primary ways of expressing what you have in your mind. And writing is an important part of communication because it allows you to engage and pique the interest of a massive audience.

However, a strong vocabulary is something essential for inspiring writing. But even the best writers sometimes find it difficult to find the right words and vocabulary to express their ideas and emotions.

With Article rewriters like Quillbot and its best Alternatives, you can broaden your vocabulary and get more chances to uplift your writing skills and impress your readers.

Aside from that, an article rewriter allows you to automatically replace the right words within your text.

As a content creator, these tools are useful whenever you need unique and compelling content in a short period of time, or if you want to develop new ways to represent old information.

However, relying solely on AI is not a good idea. After using any of these tools to fine-tune an important paper, blog post, article, or news, you should always take the time to proofread every word to ensure your content sounds correct on a human level.

What is QuillBot?

QuillBot is an AI paraphrasing tool that can be used to rewrite, paraphrase, summarize, change the structure of content, cite sources, and check plagiarism on various platforms such as the web and as an extension in any web browser or text editors such as Microsoft Word and Google Docs.

This tool is useful for summarizing and paraphrasing articles, blogs, research papers, and documents into brief paragraphs or rewritten sentences. It will extract the most important information and present it differently with unique words and vocabulary while keeping the original meaning and context of the old text.

You can’t afford to ignore a tool like QuillBot if you’re a writer, student, or researcher. 

Quillbot works in such a way that you can always refresh the rewritten text to make it more unique. You can rephrase the text as many times as you need to until you get the desired result.

What is Spinbot?

Spinbot is a free, automatic rewording tool for rewriting or paraphrasing text into multiple versions. 

Spinbot Paraphrasing tool
quillbot vs spinbot - user interface

Spinbot User Interface

This online tool has a very clean user interface that makes paraphrasing so much easier.

It is designed with two text boxes, one with the original text and one with the rewritten text. These text boxes have been arranged side by side so that you can compare and modify the results on the same screen.

You can rewrite your content by copying and pasting it into the text box or typing it manually, then clicking the rewrite button. Following the rewriting, there is a copy button that allows you to copy the paraphrased content.

If you are using Spinbot for free, you’ll be presented with targeted ads on the side and below the tool. There’s also a CAPTCHA you must complete to be able to rewrite text with this tool.

However, for paid users, you don’t have to worry about the ads or CAPTCHA.

Quillbot User Interface

Quillbot also has a very slick user interface that makes it very easy to paraphrase content.

It comes with two text editors next to each other, just like Spinbot. On one side, you type or paste your text, while the tool rewrites it on the other text box.

This tool’s design is very clever because it simplifies things for the user. It ensures easy comparison between the original and modified texts, side by side.

Additionally, Quillbot offers a wide variety of writing tones, so you can sound however you like.

You can also control the degree to which the tool alters your text using the adjustment controls called Word Flipper. Setting the Word Flipper to a lower level will result in Quillbot making the fewest edits to your text. But if this Word Flipper is set to a high level, the tool will rewrite your text using entirely new words and sentence structure whilst trying to convey the same idea.

It is worth noting that when using the Word Flipper in Quillbot, less text modification means more accurate results; and more text modification means less accurate results.

Thus, if you want a good balance between accuracy and content uniqueness, you’ll need a moderate Word flipper setting.

User Interface Winner: Quillbot

Since Quillbot has no ads on its website, it’s a no-brainer that its user interface is cleaner and more intuitive than that of Spinbot.

Even though both tools have similar design and layout, the ads on Spinbot are very destructive and the CAPTCHA feature also affects the overall user experience.

Quillbot Vs Spinbot: Quality of Rewrites

quillbot vs spinbot - output quality

The most important factor in this comparison is the accuracy and quality of the paraphrased content. There is no point in having all the bells and whistles available in a tool if it doesn’t deliver the quality results users expect.

When it comes to the quality of output, Quillbot blows Spinbot out of the water.

Quillbot uses the power of AI to first understand your content, then rewrites the text based on the context in which it was originally written. This approach ensures that the paraphrased version does not sound out of context from the original whilst presenting the meaning in an entirely new way. This is exactly what one would expect from a paraphrasing tool.

Spinbot, on the other hand, does not comprehend the content before rewriting it; instead, it simply replaces words with synonyms that may or may not be humanly readable, sometimes with numerous grammar errors.

The following are some of the amazing things Quillbot can do to your content with each rewrite.

  • Quillbot Completely Restructure Your Sentences: As previously stated, Quillbot uses artificial intelligence to understand the meaning of each sentence, then rewrites it from scratch while optimizing for uniqueness and readability. Quillbot can completely revamp your sentences while preserving their overall meaning and context.
  • Quillbot Enriches Your Text: Because the AI technology understands your content, it can clearly identify and add LSI keywords, creating each result unique and primed to perform better for additional keywords in Search Engines.
  • Quillbot can Describe the Same Ideas Differently: It can produce a crapload load of different ways to express the same concepts. This not only prevents duplicate content but also offers excellent copy alternatives and can help you overcome writer’s block.
  • Quillbot Improves the Quality of Content: This tool corrects any spelling or grammar errors as it parses your text, making your final draft even better than the originals.
  • Quillbot Improves Content Clarity: To help you better express your thoughts, this tool can help you rewrite any content that is too long or complicated to understand.

With all these incredible features included in Quillbot, it is very difficult for a tool like Spinbot to compete.

Spinbot Vs Quillbot: Tool Features

quillbot vs spinbot - Tool Features

In this section, we would like to compare the features of these tools.

However, in terms of features, there’s simply no comparison. This is because, aside from the main word replacer tool, Spinbot offers nothing else.

Thus, we will examine some of Quillbot’s best features to see how they can assist you in creating high-quality rewrites.

Vocabulary enhancement feature

QuillBot’s vocabulary-building feature is one of its most useful extras.

This feature is great for both improving your writing and expanding your vocabulary.

It has the option to use synonyms to a greater or lesser degree. This feature can be used if you only want to change a few words in your sentences. However, the entire sentence can be rewritten for you.

Writing Modes Feature

Quillbot Modes is a feature that allows you to alter the tool’s focus when paraphrasing content. Each mode can be used to focus on specific aspects of your content. This feature is one of the things that make the tool so much useful.

Quillbot comes with up to seven modes in total, which are briefly described below: 

  • Standard Mode. This is the default mode. To sound as natural as possible, it strikes a balance between changing the text and maintaining the original meaning.
  • Fluency Mode. This mode ensures that there are no grammatical errors and that the text sounds natural. In Fluency mode, the least amount of changes are made, but the meaning remains unchanged. Synonyms are set to the lowest level. 
  • Formal Mode. This mode enhances the appearance and sound of the text. This is an excellent choice for academic or business writing. 
  • Simple Mode. In this mode, your content is made easier to read and less difficult to understand.
  • Creative Mode. In this mode, the most significant changes are made to the text, making it appear and sound completely different. If you use this mode, it’s possible that the meaning will be distorted. 
  • Shorten Mode. This mode condenses the text while retaining its original meaning. This helps reduce overall word count.
  • Expand Mode. This mode attempts to make the text as long as possible by including as many words as possible. This mode is very useful in situations where you require a higher overall word count.

The Standard and fluency modes are the only ones available in the Quillbot free plan. Premium users will have access to all the other Modes, including the Creative, Formal, Shorten, and Expand modes, as well as other premium features.

Thesaurus powered by AI

The flexibility of QuillBot allows you to find the most appropriate synonym for your words and phrases.

Smart thesaurus suggestions are provided for each word in the sentence that has been changed by the artificial intelligence.

I believe that this will be the most distinctive and satisfying feature to finetune your content after it has been paraphrased.


You have the option of integrating QuillBot with a variety of text editors, including Microsoft Word and Google Docs.

Someone who writes on a regular basis will find this to be an excellent option.

Quillbot also has a Google Chrome Extension that you can use to paraphrase text on any website. 

Grammar check

QuillBot is an all-in-one writing tool.

It has a Grammar checker that improves your sentence quality and structure even more. It uses its AI to correctly understand your sentences and paragraphs.

Instead of manually checking each word for spelling, punctuation, and other grammatical errors, use QuillBot’s Grammar check.

After you’ve finished your draft, the Grammar Checker can scan your writing and notify you of any issues in your write-ups, allowing you to see what’s wrong and quickly fix it.

Summarizing tool

QuillBot’s rapid text summary tool, commonly referred to as the Summarizer, assists you in staying on top of your reading list.

Allow QuillBot’s AI to sift through research papers, news articles, or long emails to find key points and provide you with a high-level summary of the subject.

Quillbot Plagiarism Checker

The plagiarism checker in this tool examines and displays in real-time whether any of your writing failed to properly attribute authorship to anything that was previously published on the internet, in books, research papers, academic papers, or news sources.

In contrast to other applications that can only check for plagiarism in one or a few languages, the Quillbot plagiarism checker can scan text in over 100 different languages.

Note: Most of these great features are only available to Quillbot’s premium accounts. If you are a free user, you’ll want to upgrade for all these premium features.

Quillbot Vs Spinbot: API Access

API is an abbreviation for Application Programming Interface.

It is a software intermediary that allows applications to communicate with one another.

API access is available to both Spinbot and Quillbot users.

This means you can integrate the technology that powers these tools into your own applications.

NOTE: Quillbot does not offer API Services anymore.
