What Is Quillbot?

QuillBot's AI-powered paraphrasing tool will enhance your writing

Quillbot shines as a paraphrasing champion in the world of writing and content creation, serving a staggering 150 million users across the globe by 2022. This AI-powered tool, established in 2017 and based in Chicago, stands out for its ability to seamlessly rework sentences, paragraphs, and entire articles to improve their quality, making it a go-to for writers, students, and professionals alike. Beyond its paraphrasing prowess, Quillbot offers a suite of features designed to elevate your writing. These include a grammar checker, an AI detector, a plagiarism detector, a co-writer, a summarizer, and a citation creator, providing an all-in-one solution for enhancing your work without the need for multiple tools​​​​.

The paraphrasing tool is especially lauded for its versatility, offering seven distinct modes—Standard, Fluency, Formal, Creative, Shorten, Simple, and Expand. Each mode is crafted to meet different needs, whether you're aiming for a professional tone, striving for brevity, or unleashing creativity. This array of options ensures that your rewritten content hits the mark, maintaining original meanings while adapting to your desired style. Notably, Quillbot supports paraphrasing in 23 different languages, expanding its utility to a global audience. Plus, with a feature that allows comparison across modes for premium users, Quillbot empowers you to select the most suitable version of your text effortlessly​​.

As of 2024, Quillbot's significance in the digital writing space is undeniable, backed by its extensive user base and innovative features. It's not just a tool for avoiding plagiarism; it's a robust platform for refining and expanding your writing, making it more accessible, engaging, and professional. Whether you're polishing an academic paper or sprucing up a blog post, Quillbot offers the functionality and flexibility to transform your writing process​​​​​​.

How Does It Work?

At its heart, Quillbot uses something called AI, or artificial intelligence, which is a fancy way of saying it can think and learn a bit like a human. This AI isn't just any kind, though; it's specifically designed to play with language, tweaking and twisting sentences just enough to make them different but still understandable. This process involves a couple of key steps and some jargon worth unpacking.

  1. Paraphrasing with AI Models: Think of AI models as really smart robots that have read a lot more books and articles than any human ever could. They learn patterns of how words and sentences are put together. When you feed Quillbot your sentence, it dives into its massive library of learned language patterns and finds a new way to say the same thing. It's like telling a story to your friend, who then tells it to someone else with their own flair.
  2. Machine Learning and Natural Language Processing (NLP): These are the brains of the operation. Machine learning means the AI gets better the more it's used. NLP is a specific type of machine learning that deals with understanding and generating human language. So, when Quillbot paraphrases something, it's using NLP to figure out not just what words mean but how they fit together in a way that sounds natural to us.
  3. Algorithm Complexity: Inside Quillbot, algorithms (a set of instructions for solving a problem) work hard to decide the best way to change your text. They consider synonyms (words with similar meanings), sentence structure, and even the tone. It's a bit like a chef tweaking a recipe to get the flavor just right. The AI decides on the fly which words to swap, how to rearrange the sentence, and what changes will keep the original meaning intact.
  4. User Input and Customization: You're not just a bystander in this process. By choosing different modes (like Standard, Fluency, or Creative), you're telling Quillbot how adventurous you want it to be with your text. It's akin to adjusting the spiciness level of your food order. The more you play with these settings, the more you tailor the output to your liking.


  • Versatility in Writing Assistance: Quillbot is celebrated for its range of tools, including paraphrasing, grammar checking, and summarizing, making it a robust aid for writing tasks across academic, content creation, and professional domains​​​​.
  • User-Friendly Interface: Many users appreciate Quillbot's straightforward and intuitive interface, which simplifies the writing and editing process​​​​.
  • Effective Paraphrasing Tool: Its paraphrasing tool, leveraging GPT-3 technology, is highly praised for its ability to creatively rewrite text while maintaining the original meaning, offering various writing modes for flexibility​​​​.
  • Valuable for Academic Writing: The platform's integration with citation generators and plagiarism checkers is particularly beneficial for students and researchers​​​​.
  • Enhanced Productivity: Users have reported that Quillbot significantly speeds up their writing process, making it easier to produce error-free, high-quality content quickly​​.


  • Limited Free Version: The free version comes with strict limitations on character counts and available features, nudging users towards the premium version for full functionality​​.
  • Occasional Technical Glitches: Some premium users have experienced technical issues with extensions and reported delayed support responses​​.
  • Inconsistency in Paraphrasing Quality: While the paraphrasing tool is generally effective, some users have noted that it can sometimes alter the meaning too much or produce less clear sentences, requiring manual editing​​.
  • Premium Cost Considerations: The price point for the premium version, although offering comprehensive features, may be a consideration for individuals or organizations on a tight budget​​.
  • Support and Responsiveness: A few users have expressed dissatisfaction with the customer support's response time, which can impact user experience, especially when encountering technical issues​​.

2 Main Features Of Quillbot

While some of its functionalities overlap with other popular software like Google Docs, Microsoft Word, and Grammarly, Quillbot's paraphraser and summarizer offer unique benefits. Let's get into these features to understand how they can aid your writing endeavors.

1. The Paraphraser

The paraphraser is Quillbot's flagship feature, designed to help you rewrite content to make it unique while attempting to maintain or improve clarity. This tool is particularly useful when you need to present existing information in a new light or avoid plagiarism issues. It operates by analyzing the input text and suggesting alternative ways to express the same idea, often by replacing words with synonyms or altering sentence structures. The main use case of Quillbot is to paraphrase text in an attempt to deceive or bypass the popular academic AI-detector known as Turnitin.

How It Works

Upon entering your text, the paraphraser offers different modes of rewriting, such as Standard, Formal, Creative, and Simple, among others. Each mode has a specific use case:

  • Standard Mode is the go-to for general content rewriting, striking a balance between changing the text and keeping its original meaning.
  • Formal Mode elevates the language, making it suitable for professional or academic contexts.
  • Creative Mode introduces a higher level of creativity, potentially altering the original message but in a way that might spark new ideas.
  • Simple Mode simplifies the text, making it more accessible to a broader audience.


Experiment with different modes to see which one best suits your content's purpose. Keep in mind that while the paraphraser can significantly aid in making content unique, it might sometimes alter the meaning too much or not enough. Always review the suggested changes to ensure they align with your intended message.

2. The Summarizer

The summarizer tool compresses and simplifies your text, focusing on extracting the core message. It's particularly handy for condensing long articles, reports, or studies into a digestible format.

How It Works

You input the text you wish to summarize, and Quillbot works to condense it while attempting to retain the original meaning. The tool provides options for the length of the summary, allowing you to choose how much you want to reduce the original text.


While the summarizer is efficient at distilling long texts into essential points, it may sometimes oversimplify, losing nuanced details. It's best used when you need a quick overview or are trying to grasp the main points of lengthy content. Always compare the summary to the original to ensure no critical information has been omitted.

Utilizing Quillbot to Enhance Your Writing

Quillbot's paraphrasing and summarizing tools can be powerful allies in your writing process, offering ways to refine and condense your work efficiently. However, they are tools to assist rather than replace your judgment and creativity. Here are some steps to make the most out of Quillbot:

  1. Start with a clear goal for what you want to achieve with your text.
  2. Select the appropriate tool based on whether you need to rewrite or summarize the content.
  3. Choose the right mode that aligns with your text's purpose and audience.
  4. Review and edit the output to ensure it meets your expectations and maintains the original's essence.

Plans & Pricing

Quillbot premium plan features compared to free plan

Here's a detailed breakdown to guide beginners through what Quillbot has to offer and help them make an informed decision.

Quillbot Free Plan

The no-cost version of Quillbot is a great starting point for those new to the tool. It provides access to two essential writing modes:

  • Standard Mode: Aims to rewrite your text to maintain its original meaning while possibly making it clearer.
  • Fluency Mode: Focuses on ensuring your text is readable and free from errors, though one might wonder why Standard Mode doesn't inherently include this error-free guarantee.

With the free version, you can paraphrase up to 125 words at a time, offering a taste of Quillbot's synonym capabilities. This limited access serves as a practical introduction to its potential in refining your writing.

Quillbot Premium

For users requiring more robust features, Quillbot Premium presents a monthly cost ranging from $8.33 to $20, depending on your subscription model—monthly, semi-annually, or annually. This investment unlocks a suite of advanced features:

  • Expanded Writing Modes: Beyond Standard and Fluency, you gain access to Formal, Simple, Creative, Expand, and Shorten modes. Each serves a unique purpose, from professionalizing your language to condensing or elaborating your text for clarity or detail.
  • Enhanced Synonym Options: The premium plan allows for a broader selection of synonyms, empowering you to fine-tune your text with greater precision.
  • Plagiarism Detector and Grammar Checker: These tools add an extra layer of polish to your work, ensuring originality and grammatical correctness.
  • Faster Processing and Comprehensive Scans: Premium users enjoy quicker analysis and the ability to review results across all seven modes simultaneously, aiding in selecting the most fitting rendition of their text.
  • Freeze Words Feature: Particularly useful for specialized content, this option prevents specific keywords from being altered during the paraphrasing process.
  • Increased Limits: The character cap is removed, and the summarizer's word limit jumps from 1200 to 6000 words, offering substantial room for more extensive editing tasks.

Making Your Decision

Deciding whether Quillbot's premium features justify its cost depends on your specific needs and usage. While alternatives like ChatGPT offer similar functionalities for free, Quillbot's specialized tools, particularly for academic writing and content creation, provide a tailored experience that some may find invaluable.


a writer evaluates three different text rewriting tools


First up, Quillbot and Wordtune are quite similar in the quality of output they provide. Both do an excellent job at rewriting text in a way that passes plagiarism checks, which is crucial if you're looking to create content that stands out as original. I've used both for various projects and found that they really help in refining my drafts and giving them a new voice.

Pricing is a big factor when choosing a tool, and here's where things get interesting. Wordtune starts at $10 per month, which is pretty reasonable if you're using this kind of service regularly. Quillbot, on the other hand, offers its plans from $15 monthly or an even more affordable $80 yearly option. If you're planning to use a rewriting tool throughout the year, Quillbot's annual plan is definitely worth considering for the savings.


Now, WordAI stands a bit apart from the other two. Yes, it's the most expensive, with a monthly fee of $57, or $27 per month when billed yearly. But there's a reason for the higher price tag. WordAI offers API access, which is a big deal if you're a power user looking to integrate rewriting capabilities directly into your own apps or workflows. For me, this has been a game-changer for larger projects where automation is key.

Undetecable AI

When comparing Quillbot to Undetectable AI, the focus shifts to the specific use cases and advantages each tool provides. Quillbot excels in producing fluent, well-structured paraphrases, making it an excellent choice for content creators who prioritize readability and style. It's priced at $19.95 per month, with significant discounts for semiannual and annual plans. Quillbot also offers a free version for basic paraphrasing needs, though it's limited to 125 words per instance.

On the other hand, Undetectable AI is tailored for bypassing AI detection systems, often producing content that closely mimics human writing by introducing minor errors that make it less detectable. Its pricing is more flexible, starting at $14.99 per month based on word volume, with annual plans that can reduce costs to as low as $5 per month. Undetectable AI's strength lies in its ability to produce content that avoids AI detection, making it suitable for applications where this is a critical requirement.

So, Which Should You Choose?

It really comes down to what you need. If you're looking for a solid, affordable option for everyday writing tasks, Quillbot and Wordtune are both great choices. They're easy to use, and the quality of their output is impressive for the price. Quillbot's yearly subscription, in particular, offers great value.

For those who need more advanced features like API access for automating tasks, WordAI is worth the investment. Despite its higher cost, the time it saves me in my workflow makes it a justifiable expense.

My Advice

Based on my experience, I'd suggest starting with the free versions of Quillbot and Wordtune to see which interface and results you prefer. Then, consider your budget and whether the annual plans offer savings that match your usage patterns. For those involved in larger scale or automated projects, take a closer look at WordAI. Its advanced features could be exactly what you need, even considering the higher price.

Final Take - Thoughts On Quillbot

Firstly, let's address the importance of creating original content. Writing on your own enhances your skills, allowing you to express ideas uniquely and personally. It's a process that not only improves your writing abilities but also boosts critical thinking and creativity. When you write or paraphrase by yourself, you engage deeply with the content, leading to a better understanding and retention of the information.

ChatGPT: An Alternative to Quillbot

While Quillbot is designed for paraphrasing, ChatGPT offers a broader range of functionalities, including writing assistance and grammar checking, at no cost. For beginners and seasoned writers alike, ChatGPT can be an invaluable tool. Its ease of use and versatility make it a preferred option for many. Whether you're looking to draft an email, write an essay, or simply need help rewording a sentence, ChatGPT can assist in a user-friendly manner.

Considering Use Cases for Quillbot

You might wonder if there's a scenario where Quillbot could be the better choice. It's a fair question. Quillbot specializes in paraphrasing, which, in theory, could help with quickly finding alternative ways to express the same idea. However, the value of manually paraphrasing—engaging with the material, understanding it thoroughly, and then conveying it in your own words—cannot be overstated.

The Bottom Line

In summary, while tools like Quillbot have their niche, the benefits of using ChatGPT, especially for beginners, are significant. It offers a broad range of functionalities for free, making it a more versatile companion in your writing journey. But remember, the ultimate goal is to improve your own writing skills. Tools should support your development, not replace the valuable process of learning and growth.


QuillBot shines for students and academics, offering tools like plagiarism checkers, summarizers, and citation generators for streamlined research and writing without distraction. While it's less ideal for bloggers seeking undetectable AI rewrites, its paraphrasing tool can still enhance human-sounding content creation.
