QuillBot Review – Best Tool For Content Editor

If you’re in need of an efficient rephrasing tool, QuillBot offers a cost-effective solution with high-quality functionality. Similar to other machine learning writing software, the most advanced features and functionality are not accessible in the free plan.

However, it does deliver quality results for those who can invest in it. Despite this, even with Quillbot Premium, the tool doesn’t match the capability of producing content of Google’s standard like some other tools such as Jasper AI, leaving room for improvement in machine learning.

Nevertheless, it represents a positive step towards generating improved and more readable articles based on the input of a source piece of content.

3. QuillBot Overview

3.1. Who should use QuillBot and why?

QuillBot is available for use by a wide range of individuals, including students and bloggers, who require top-notch content.

Essentially, anyone seeking to enhance their writing quality, save time, and steer clear of plagiarism can benefit from QuillBot. The tool is particularly advantageous for students, offering a variety of student-friendly features such as the plagiarism checker, summarizer, and QuillBot Flow. Students can utilize the summarizer to produce annotated bibliographies and then employ the citation generator to complement these summaries.

The QuillBot Flow function is effective as an all-in-one text editor. With the research feature, users can avoid switching between windows and automatically generate in-text citations to prevent unintentional plagiarism. This setup can help minimize distractions during the writing process.

However, for non-academic bloggers, QuillBot Flow may not be as user-friendly as other AI writing tools available. It could be beneficial for rewriting AI-detectable paragraphs, although the rewrites may still be detectable at times, making it inconsistent in beating the AI detector.

3.2. QuillBot Main features

3.2.1. The Paraphraser

Quillbot AI offers a paraphrasing tool that allows writers to reword text while maintaining its core message. It is a valuable resource for students and aspiring writers, and it does not require users to sign up for an account. Users can choose between “Fewer Changes” or “More Changes,” and premium users have access to the most extensive adjustments.

Paraphrase Modes

QuillBot AI helps users by rephrasing and improving text. It offers seven different modes, each designed for specific goals, to improve the quality and readability of written content. Whether aiming for clarity, professionalism, creativity, or conciseness, QuillBot AI has a mode to meet your requirements.

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 is the default setting, aiming to balance text modification for clarity and fluency while preserving the original meaning. The outcome is a polished text that retains its natural flow and readability.

Upon clicking the Rephrase button, Quillbot promptly provided a reworded output in Standard Mode. It’s worth noting that the extent of paraphrasing depends on the level of synonyms set in the Synonyms bar to the right of the Modes bar above the content. The higher the level, the more freedom you grant Quillbot to alter 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.”

Standard Mode - Low Synonyms
Standard Mode – Low Synonyms

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.”

Standard Mode - Higher Synonyms
Standard Mode – Higher Synonyms

By altering just a single word, you can observe minimal change, but when working with larger sections of text, Quillbot will introduce a greater variety of synonyms.

2. Fluency Mode

In Fluency Mode, QuillBot AI guarantees that the text is grammatically correct and easily understandable. It makes only essential corrections, mainly focusing on grammar and ensuring the text flows naturally. It minimizes the use of synonyms to maintain 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.”

Fluency mode

3. Formal Mode

Formal Mode is the best option for individuals operating in academic or professional settings. It enhances the text to convey a more refined and professional tone, rendering it appropriate 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.

Formal Mode

4. Academic Mode

Afterwards, we rephrased the identical information in Academic Mode. In contrast to other modes, it lacks a Synonyms bar. Instead, it appears to provide the content with additional details and wording appropriate for an academic context.

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.

Academic Mode

5. Simple Mode

Simple Mode makes the text easier to grasp, ensuring it’s clear and understandable for a wider audience. It’s a great option when you need clear and direct communication.

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.

Simple Mode

6. Creative Mode

If you want to explore your creative side and craft completely original content, Creative Mode is the perfect choice. This mode significantly transforms the text, possibly changing its initial meaning. It’s a valuable resource for content creators aiming to infuse a new perspective into 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.

Creative Mode

7. Expand Mode

Expand Mode serves as an ideal tool for individuals seeking to augment the length of their text. By incorporating additional words and elaborating on details, it upholds the essence of the original meaning. This mode is particularly beneficial for endeavors demanding a greater 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.

Expand Mode - Low Synonyms
Expand Mode – Low Synonyms

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.”

Expand Mode - High Synonyms
Expand Mode – High Synonyms

8. Shorten Mode

Shorten Mode is your solution for trimming down the word count without losing your text’s essence. By removing unnecessary words and phrases, it presents a concise version of your content while preserving its core meaning.

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.

Paraphraser Statistics

The ‘Statistics’ tool provides valuable information about text complexity and readability, assisting writers in tailoring their style to specific tones and audiences. Premium subscribers gain access to tonality analysis, which evaluates reader perceptions to improve persuasive writing. Using the “Fluency” mode with the same content has generated the following statistics.

3.2.2. The Grammar Checker

Quillbot AI provides a user-friendly and free Grammar-checking feature that doesn’t necessitate sign-up. Upon pasting your text into Quillbot’s editor, it detects and highlights grammatical errors encompassing punctuation and spelling. The convenient “Fix All Errors” option enables swift correction of multiple issues simultaneously. This Grammar Checker elevates writing accuracy and uniformity by promptly identifying potential errors in red, streamlining the editing process. The real-time underlining and instant correction feature save writers time and enhance 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.

When you paste the text into the Grammar Check, it will detect potential errors within the content. By placing your cursor on the underlined words, it will show you the errors individually.

3.2.3. Summarizer

Users can select between Short and Long summarization options to manage the level of detail. The Short summarization provides a quick overview, ideal for grasping central ideas or quickly scanning through multiple articles. Conversely, the Long summarization offers a more comprehensive summary, suited for deeper analysis or gaining a thorough understanding of the text.

Quillbot AI’s Summarizer employs natural language processing to extract crucial information while maintaining the original context. It provides two summarization types: Key Sentences and Paragraph modes.

For example, by inputting a block of content into the summarizer text area and utilizing the Key Sentences feature, the tool generated five concise points summarizing the content effectively.


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

Summarizer - Summary Length
Summarizer – Summary Length

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

Summarizer - Paragraph
