Quick Overview for Quillbot’s Paraphraser

Our expectations were very high for Quillbot’s paraphraser. This tool has a wide selection of rewriting modes, as well as a variety of languages to match almost all educational needs. The quality of paraphrasing was great both in terms of readability and low AI detection and plagiarism results in both the personal essay and the scientific text, which can’t be said about the academic-styled paragraph.

Quillbot Paraphraser Review
An infographic with a short Quillbot review describing the ways it was tested and how it received an A*Help Score: 92/100

What does the process of writing an assignment typically include? Firstly, obviously pouring yourself a cup of coffee or a strong tea to pull you through that all-nighter, because ain’t no way the other deadlines aren’t already breathing down your neck. Next, you should reshape all of your buzzing thoughts from chaos to at least controlled chaos. Then, researching the topic, finding literature and other resources, which also takes a lot of time. But then – boom – you remember that you already did a similar paper. What a relief, right? Wrong! If you just copy the previous task you’ve already submitted or rely too much on outside sources, you risk getting punished for plagiarism. 

Crafting papers, reports, and assignments requires not only a deep comprehension of the topic at hand but also the ability to convey that knowledge without falling into the trap of plagiarism. Students often turn to rewriting services to ease the workload, and one of the popular options tends to be Quillbot. So, we were curious to know whether Quillbot lives up to its title of one of the best paraphrasers out there.

Quillbot Paraphraser Mystery Shopping Experiment

You might have a question: – what is there to test about a paraphraser? It’s simple, you just open it and copy-paste your text, right? But here at AcademicHelp, we approach every service evaluation very seriously and create specific criteria based on three main aspects: value for money, overall experience, and quality of help. Each of these sections has its own subcategories, designed to assess the service in the fullest possible way. If you are interested in learning more about How We Test Paraphrasers, here’s a short breakdown.

In order to test Quillbot’s ability to create new and original texts while keeping the main idea of submitted input, we decided to task it with three different paragraphs. The first text was a typical personal narrative essay talking about the feeling of gratitude. This is the most common type of work students tend to submit, so it was essential for us to check it. The second text was a bit more complicated since it was a snippet from Florence Nightingale’s biography. Such texts tend to get flagged by plagiarism checkers, if students don’t put in enough effort to rewrite them. So, we decided to give it special attention. The third and final text was the most complicated – a paragraph from a biology textbook, filled with specific terminology and hard-to-understand sentence structure. This text was, so to say, the final boss of our mystery shopping.

👩 Biography of Florence NightingaleAcademic125 words
🌿 Ultrastructural changes in chloroplasts of cold-tolerant plants Scientific129 words

After rewriting all three texts, we proceeded to run them through our AI Detector and Plagchecker, which are a part of the AcademicHelp Learning Hub. This way, we were able to see how well the paraphrased texts could handle various tests. These tend to be put into place by professors to make sure that academic integrity is still in place. This part was also taken into consideration and reflected in the A*Help score, so you would clearly see which service had more problems with various detectors.

Quillbot & Paraphrasing Help — 51/55 ⭐⭐⭐⭐⭐

Well, the most intriguing part – the quality of paraphrasing. This process is not as simple as one might think, since the whole purpose of rewriting is very intricate; the tool has to create readable, understandable, and original text that will not only keep the main idea in place but also dodge plagiarism checkers and AI detectors professors might use.  We were pleasantly surprised with Quilbot after we had tasked it to paraphrase three texts of different difficulty levels, including a simple essay, a biography of a historical figure, and a paragraph from a biology textbook with specific terminology.

It is necessary to mention that all three texts had around the same word count after paraphrasing, which not all services unfortunately keep. The style, however, was slightly different in the third text, but it was far more “digestible” than the original. Quillbot bravely overcame every single challenge we posed and scored “High readability”; the only mediocre thing was the plagiarism detection results. The idea behind our mystery shopping was to check if the paraphraser could handle a piece of widespread and overused information like a biography. After running the second rewritten text through our Learning Hub tools it showed 30% of plagiarism detected and 41% of AI in the output. Although it is still an ‘okay’ result among other paraphrasers, this fact only highlights the need to proofread your assignments and put in a little more effort, as well as a personal touch, even if the tool is as high-quality as Quillbot.

Apart from that, the other aspects of paraphrasing were great. The factual information remained the same, while the structure of the text was changed, and that is exactly what we wanted to see. Both the personal narrative and the scientific text showed 0% in AI detection and plagiarism. Most importantly, the style remained the same and there were no additional mistakes.

So, is Quillbot a good paraphraser? The answer is a confident “yes”. Not only did it rewrite the texts in a swift manner, but also kept the necessary information and styles. This kind of service is just what a student wants when feeling overwhelmed with assignments and in need of a little help.

Quillbot Paraphraser Value for Money — 24/25 ⭐⭐⭐⭐⭐

Achieving the perfect score for value-for-money usually means having the ideal mix of affordability, quality, and the capacity of the service to meet user demands. In our reviews, this ratio forms a crucial part of our evaluation and stands as the touchstone for excellence among services. 

Quillbot is extremely well-known for its text creation services, and it proves its leadership even when it comes to paraphrasing. The service has a wide range of rewriting modes, such as simple, advanced, creative, academic, formal, and even custom. It also has a choice of more than 20 languages, including several English variations. Although you have to squeeze into a tight limit of 125 words when using it for free, you can get unlimited words by purchasing a Premium plan for $9.95/month.

The service provides a very useful “synonyms” feature, which allows you to pick out words you think will fit best into the text. You can control synonym changes via a slider and either ask Quillbot to add fewer or more different words. Users who purchase a Premium plan can also look through their paraphrasing history, as well as compare several modes to choose the perfect one for them. And the list doesn’t end there! Quillbot also allows you to control the tone of voice for your text which is like a cherry on top of this three-tier cake.

Overall, Quillbot almost got the perfect score – 24/25 pts for value-for-money, which reflects the platform’s willingness to address most customers’ needs and preferences. The only thing that is not perfect is the word limit in Quillbot’s free version, which can slow down the process, but we don’t consider it to be such a major deal in comparison to other high scores.
