This review thoroughly explores QuillBot AI, focusing on its key features, pricing structure, and strengths and weaknesses.

What is QuillBot AI?

quillbot AI tool

QuillBot AI is a leading AI writing companion and paraphrasing software designed to help anyone elevate the quality of their writing. At its core, it functions as one of the best AI rewriter tools to edit, rephrase, and enhance content like a professional.

It presents various features, including grammar checking, plagiarism detection, and content summarization. As such, QuillBot AI delivers substantial benefits for academics, essayists, and writers. Creating high-quality professional content can be time-consuming, and Quillbot streamlines the process using AI to improve your writing quickly, offering real-time suggestions and one-click solutions. Plus, it is an all-in-one solution that replaces the need to invest in multiple tools, making it cost-effective.

The versatility of the software caters to a diverse audience. While students can utilize its various writing tools, professional writers can efficiently collaborate and summarize lengthy text. If you want to improve your writing process, whether writing an email, an essay, or a long-form blog article, you will find Quillbot AI to be a valuable addition to your writing toolkit. It can revolutionize your writing process to produce surprising results.

How Quillbot AI Works

You can access QuillBot by visiting their online platform on their website. You don’t need to create an account; you can use a free version of QuillBot with limitations. Once you are there, you will see the available tools in the left sidebar. Click any of the tools to launch the user interface for each.

QuillBot User Interface

Each tool will have a consistent layout with different features that you can use to start refining your content. For example, when using the Grammar Checker, you can copy and paste your content into the user interface. QuillBot will readily analyze your text, pinpointing broken sentences and grammatical errors you can fix with a single click.

And the other other tools share the same easy-to-use interface and functionality. For instance, the Summarizer makes condensing long-form content or essays easy. Paste your text to generate a summary of key points. Additionally, it features a plagiarism checker, which helps identify and fix plagiarized content to ensure the originality of your content.

QuillBot’s AI functions by learning from datasets. Comprehending grammar, spelling, punctuation, tone, sentence structure, and readability, these datasets serve as knowledge accumulations. So, when users regularly disregard a specific suggestion, the AI adjusts to present more contextually relevant alternatives.

Breaking Down QuillBot AI Features

QuillBot AI offers several features for easy and effective content organization. We’ll delve into these features now.

1. The Paraphraser

QuillBot AI includes a paraphrasing tool. It empowers writers to rephrase text while preserving its central message. It’s an ideal tool for students and aspiring authors, requiring no account signup. Options for ‘Fewer Changes’ or ‘More Changes’ are available, with premium users getting maximum adjustments.

Paraphrase Modes

QuillBot AI assists users in paraphrasing and refining text. It employs seven unique modes, each tailored to specific objectives, to enhance the quality and readability of written content. Whether striving for clarity, professionalism, creativity, or conciseness, QuillBot AI offers a mode to suit your needs.

Here is an example sentence I added to the paraphraser text input area:

“It was a tough match. After three hours of immense struggle, I was able to get the job done.”

1. Standard Mode

Standard Mode serves as the default setting. It balances modifying the text for clarity and fluency while preserving the original meaning. The result is a refined text that maintains its natural flow and readability.

After clicking the Rephrase button, QuillBot swiftly provided a paraphrased output in Standard Mode. It merits noting that the level of paraphrasing hinges on the level of synonyms you set in the Synonyms bar at the right of the Modes bar above the content. The higher the level, the more liberty you give QuillBot to change the words of the original content.

The ensuing result was generated with a low Synonyms bar:

“It was a challenging game. I had to struggle for three hours before I was able to finish the task.”

quillbot ai standard mode

The following result was generated with a maximum level of Synonyms:

“It was a challenging game. I had to battle for three hours before I was able to finish the task.”

quillbot ai standard mode

With just one sentence, you can see that only one word changed, but with larger blocks of content, you will see that QuillBot will make more word changes with a higher level of synonyms.

2. Fluency Mode

In Fluency Mode, QuillBot AI ensures that the text is grammatically sound and genuinely readable. It makes minimal changes, primarily correcting grammar and providing the text sounds natural. Synonym substitutions are kept to a minimum, preserving the original meaning.

We paraphrased the same content in Fluency mode. It generated the following output:

“It was a difficult match. I completed the task after three hours of intense effort.”

quillbot ai fluency mode

3. Formal Mode

Formal Mode is the ideal choice for those working in academic or professional contexts. It transforms the text to sound more polished and professional, making it suitable for business reports, academic papers, and formal documents.

We paraphrased the same content in Formal Mode. It generated the following output:

It was a difficult match. After three hours of arduous effort, I was able to complete the task.

quillbot ai formal mode

4. Academic Mode

Then, we paraphrased the same content in Academic Mode. Unlike the other modes, it doesn’t have any Synonyms bar. Instead, it seemed to give the content more details and wording suitable for academia. It generated the following output:

The contest was challenging. Following a prolonged period of three hours, characterized by significant exertion and effort, I successfully completed the task at hand.

quillbot ai academic mode

5. Simple Mode

Simple Mode simplifies the text, making it easier to understand and more accessible to a broader audience. It is an excellent choice when clarity and straightforward communication are essential.

We paraphrased the same content in Simple Mode. It generated the following output:

It was a hard game. I was able to finish the job after three hours of hard work.

quillbot ai simple mode

6. Creative Mode

Creative Mode is the way to go if you’re looking to unleash your creativity and generate entirely unique content. This Mode substantially changes the text, potentially altering the original meaning. It’s a valuable tool for content creators seeking a fresh spin on their writing.

We paraphrased the same content in Creative Mode. It generated the following output:

That was one intense contest. It took me three hours of relentless effort, but I finally completed the task at hand.

quillbot ai creative mode

7. Expand Mode

Expand Mode is perfect for those aiming to increase the length of their text. It adds words and details while retaining the original meaning, making it valuable for projects requiring a higher word count.

We paraphrased the same content in Expand Mode. It generated the following output:

It was a difficult match to watch. I had to put in a lot of effort for three hours before I was finally successful in completing the task.

quillbot ai expand mode

Then, we produced an output with a high level of Synonyms as follows:

“The contest was a challenging one. I was able to finish the work, despite the fact that it took me three hours of intense effort.”

quillbot ai expand mode

8. Shorten Mode

Shorten Mode comes to the rescue when you need to reduce the overall word count while maintaining the essence of your text. It trims unnecessary words and phrases, delivering a concise version of your content.

Lastly, we paraphrased the same content in Shorten Mode. It generated the following output:

The match was hard. I finished after three hours of intense struggle.

quillbot ai shorten mode

Paraphraser Statistics

The ‘Statistics’ feature offers insights into text complexity and readability. It aids writers in adjusting their style to the desired tone and audience. Premium subscribers unlock tonality analysis, which assesses reader perceptions to enhance persuasive writing.

I have used the same content as the previous one in the “Fluency” mode. It has generated the following statistics.

quillbot ai statistics

The Statistics of the generated content are based on the following aspects:

  • Average words in a sentence
  • Average Syllables in a word
  • Readability
  • Sentence Count
  • Word Count
  • Character Count
  • Percent Change
  • Longest Unchanged Words

Paraphraser Settings

quillbot ai settings

The “Settings” feature in the Paraphraser tool provides options to control how you want your content to be paraphrased and how you want the results to be displayed on the interface. In terms of paraphrasing the content, you choose the following:

  • Paraphrase quotations
  • Use contractions
  • Prefer active voice

Under the Interface options, you can select the following:

  • Use yellow highlight
  • Show tooltips
  • Show legend
  • Show changed words
  • Show structural changes
  • Show the longest unchanged words

Overall, these settings do seem to give users more control and help them identify changes to their content much easier.

Paraphraser Compare Modes

Compare Modes is a valuable feature exclusively available to premium users, offering a comprehensive view of how a sentence is transformed across different modes within the platform. This feature enables users to evaluate and choose the most suitable rendition for their content by comparing various paraphrased versions. To access Compare Modes, locate and click on the dedicated icon in the settings bar on the right side of the page.

quillbot ai compare modes

Once activated, Compare Modes opens a sidebar on the right-hand side of the screen, displaying the original sentence before paraphrasing and the results generated by all available modes simultaneously. The system defaults to the effect produced by the Mode in which the sentence was paraphrased. You can easily click the “Select” button next to the desired text to select your preferred sentence, seamlessly replacing the paraphrased sentence in your results. Additionally, you can further modify individual sentence results by clicking on circular arrow icons or making copies of them with a simple click on the copy icon. This powerful feature empowers users to fine-tune their content according to their specific needs and preferences, streamlining the content creation process.

Paraphraser History

By accessing the history feature, you can go through all the previous content you have modified. In my case, I checked my history, and it showed the last text paraphrased. It also shares the date and time when the content was modified.

quillbot ai history


The “Tone” feature in QuillBot AI paraphraser allows users to control and tailor the emotional and stylistic tone of their paraphrased content. With this feature, users can choose from various preset tones, such as casual, unfriendly, wordy, complex, and unclear. It ensures that the paraphrased text aligns perfectly with the desired style and intent. Whether you need your content to sound professional and academic or friendly and conversational, the Tone feature empowers you to achieve the right mood for your writing.

Paraphrasing for Different Languages

Quillbot AI supports 23 different languages for paraphrasing purposes. Not only does this make the tool more accessible, but it also comes in handy for making tweaks to the content generator by Quillbot’s translator tool.

2. The Grammar Checker

Quillbot AI offers a user-friendly and free Grammar-checking feature that doesn’t require signing up. When you paste your text into Quillbot’s editor, it identifies and highlights grammatical errors, including punctuation and spelling. With a convenient Fix All Errors option, you can swiftly correct multiple issues simultaneously. This Grammar Checker enhances writing precision and consistency. It quickly pinpoints potential errors in red, simplifying the editing process. This real-time underlining and instant correction feature saves writers time and improves productivity.

For instance, here is an example sentence I added to the grammar checker text input area:

Manchester United signed Sofyan Amrabat on a season-long loan move from Fiorentina. The Morocco midfielder has been desperate to join Erik ten Hag’s team since getting linked to the Red Devils in June. However, Manchester United’s plans differed on Deadline Day as they wanted to sign Fulham’s Joao Palhinha instead.

After copy-pasting the text into the Grammar Check, it will detect all the potential errors within the content. By putting your cursor on the underlined words, it will show you the errors individually.

quillbot ai grammatical errors

Once you remove all the errors, it will provide you with the correct grammatical content. It will generate the following content.

Manchester United signed Sofyan Amrabat on a season-long loan deal from Fiorentina. The Morocco midfielder has been desperate to join Erik ten Hag’s team since getting linked to the Red Devils in June. However, Manchester United’s plans were different on Deadline Day, as they wanted to sign Fulham’s Joao Palhinha instead.

Furthermore, it seamlessly integrates with Quillbot’s Paraphrase tool, offering a comprehensive writing experience without needing an account. Its grammar-checking feature is valuable for writers seeking error-free, professional content.

3. Summarizer

Quillbot AI provides a Summarizer tool that condenses lengthy texts or articles into concise summaries, making it invaluable for students, researchers, and professionals.

Users can choose between Short and Long summarization options to control the level of detail. The Short summarization offers a brief overview, ideal for quickly grasping the central ideas or skimming through multiple articles. In contrast, the Long outline provides a more comprehensive summary, suitable for in-depth analysis or a deeper understanding of the text.

Quillbot AI’s Summarizer utilizes natural language processing to extract critical information while preserving the original context. It offers two summarization types: Key Sentences and Paragraph modes.

For instance, I added a block of content to the summarizer text input area. Using the Key Sentences feature, the tool has created five articulate points that summarize the content.

quillbot ai key sentences short summary length

Changing the Summary Length can increase or decrease the depth of those points.

quillbot ai key sentences long summary length

Selecting the Paragraph mode will provide a summary of the content in paragraph form.

quillbot ai paragraph short summary length

Like the Key Sentences mode, the length of the summary can be changed by adjusting the Summary Length.

This feature streamlines research, study, and content review processes, enhancing productivity and comprehension for users across various fields.

4. Citation Generator

QuillBot’s Citation Generator is a valuable tool that simplifies the often complex process of citing sources in academic and professional writing. It allows users to choose from various citation styles and formats, ensuring compliance with specific guidelines and educational requirements. This feature dramatically reduces the potential headache associated with accurate source attribution.

It supports common APA, MLA, and Chicago styles, covering reference types like books and websites. With an intuitive interface, it swiftly generates in-text and complete citations, labeled and exportable to Microsoft Word. By automating this process, QuillBot’s Citation Generator saves users time and ensures proper crediting of sources, benefiting those involved in research and academic writing projects.

5. QuillBot Plagiarism Checker

Quillbot AI provides a plagiarism checker, which is a premium feature. It eliminates the need for external tools to verify content originality. Premium users can paste their content into the checker, receiving results within minutes, indicating if the content is unique or plagiarized. Premium members can scan up to 20 pages per month with this tool, making it suitable for various types of content, including research papers.

quillbot ai plagiarism results

Its plagiarism checker stands out by accommodating research paper plagiarism checks, scanning up to 20 pages (approximately 5000 words) monthly. Consequently, it proves to be a valuable resource for essayists and academic writers, ensuring the integrity of their work.

Plagiarism detection is based on identical words, minor changes, paraphrased words, and omitted words.

6. The Translator

QuillBot AI provides its users with a Translation feature, allowing them to translate text into over 30 languages, making research and writing accessible across language barriers. It offers ad-free translation of up to 5,000 characters at once, includes integrated writing tools, and provides quick and accurate translations. The best part is that it’s free, enhancing convenience and accessibility for writers and researchers.

As a test, I added a block of content in the German language. The translator automatically detected it as German.

Then all you need to do is select the language you want it translated to on the right and click the Translate button.
