QuillBot Top Features:

1. Paraphrasing Tool

I entered my author bio in the first text box, and the second text box displayed the paraphrased version generated by QuillBot AI. The tool doesn’t just rewrite text but offers alternative suggestions to refine the output.

For example, if you don’t like a particular sentence structure, you can click on it, and QuillBot will provide other rewording options and synonyms that better fit your writing style. This feature ensures your content remains clear, concise, and customized to your needs.

If you don’t like a specific word choice, you can click on the word and replace it with a synonym. For instance, in the generated output, I clicked on the word “content producation,” and QuillBot displayed various replacement suggestions like “handles,” “navigates,” and “explores,” allowing me to choose the most appropriate word for my context.

When you’re using QuillBot for free, you get limited suggestions for changes. However, upgrading to QuillBot Premium increases the number of available rephrasing options, giving you more flexibility in fine-tuning your text.

Premium users also have access to tone adjustments, allowing them to modify the text to sound more casual, formal, friendly, or professional. This feature ensures that your writing aligns perfectly with the intended audience, making QuillBot AI an essential tool for students, researchers, and content creators.

2. Paraphrase Modes

The Paraphrase Quilbot offers different rewriting modes, including:

Standard Mode: The Standard Mode balances accuracy and readability, making it ideal for general writing. It rewrites content in a way that maintains the original meaning while improving sentence flow. 

Fluency Mode: If you want your text to sound natural and grammatically correct, Fluency Mode is the best option. This mode improves sentence structure, fixes grammatical errors, and improves readability. 

Formal Mode: The Formal Mode refines text to align with academic, business, and professional standards. It eliminates casual expressions and replaces them with more structured and sophisticated language.

Simple Mode: For content that needs to be easy to understand, Simple Mode rewrites text using clear and concise language. It simplifies complex ideas, making it suitable for educational materials, instructions, and general audience content.

Creative Mode:  If you want a more engaging and expressive way to rewrite text, Creative Mode adds uniqueness and variation. 

3. Grammar Checker

The QuillBot grammar checker detects grammatical errors in the text and corrects them by providing instant suggestions. It also checks for spelling and punctuation mistakes, helping users refine their writing for better clarity and accuracy.

You can type directly in the text box or upload a document to check for errors. I entered a simple sentence to test it to see how well it worked. Now, let’s apply all the suggested corrections and observe the final result. Looks good! The output is smooth and polished similar to what Grammarly offers

.

As seen in the results, it doesn’t just catch basic errors but also suggests improvements to make sentences sound more natural and professional.

 It focuses on refining sentence structure and improving readability rather than just marking mistakes.

Now, let’s test it with a poorly written sentence. Here’s the output after applying the suggested changes. Hmm… not quite perfect. It still missed some errors. However, before judging it too harshly, we should remember that AI improves over time. With continuous updates and learning, it refines its ability to correct complex errors.

Now that we’ve explored the Grammar Checker let’s move on to the next feature!

4. Plagiarism Checker

The QuillBot plagiarism checker is an exclusive feature available to Premium users. If you need to verify whether your text is plagiarized, this tool helps by scanning your content against a vast database of online sources, academic papers, and published materials.

It doesn’t just detect plagiarism; it also assists in properly attributing sources by suggesting the correct citation formats. This makes it especially useful for research paper writers, students, and content creators who need to ensure their work is both original and properly referenced.

With real-time plagiarism reports, QuillBot clearly highlights which sections of your content are copied or missing citations. Another advantage is that it supports multiple languages, making it a great tool for users worldwide.

Premium users get 100 page scans per month, with each page consisting of up to 250 words. To use the plagiarism checker, simply paste the text or upload a file, and QuillBot will quickly scan the document for copied content.

For those dealing with academic research, professional writing, or SEO-based content, this feature ensures that your work remains authentic and properly sourced.

5. Summarizer

The QuillBot Summarizer extracts key sentences from a text and generates a concise summary. If you’ve written a report, research paper, or long article and need a quick overview, simply input your text into the summarizer tool, and it will provide a shortened version with all the essential details.

To test it, I used the QuillBot Summarizer on an essay of over 600 words, and it generated a 150-word summary. It did a great job of analyzing the entire text, selecting key points, and condensing the information into a clear and readable format.

You can also adjust the summary length by dragging the length slider at the top. I reduced the length further, and it regenerated a shorter summary of around 90 words, keeping the most important details intact.

Another useful feature is the Bullet Points option. You can choose bullet points instead of a paragraph summary, making the content easier to read and scan.

The QuillBot Summarizer is an excellent tool for students, researchers, and professionals who need quick, precise, and structured summaries for their work.

6. Translator

The QuillBot Translator functions similarly to Google Translate, allowing users to translate text into multiple languages while keeping everything within the same platform. What makes it stand out is that you can rephrase, edit, and translate your content all in one place, streamlining the writing and translation process.

One useful feature is the ability to listen to the translated text by clicking on the speaker icon below the output box. This helps with pronunciation and comprehension, making it great for language learners and professionals who need to work with multilingual content.

The QuillBot Translator supports 45 languages, making it a versatile tool for students, researchers, and content creators who need quick and reliable translations.

7. Citation Generator

The QuillBot Citation Generator creates citations for URLs, journal articles, books, online articles, news reports, and other sources. This tool ensures that users properly credit their references in academic and professional writing.

Let me show you how it works. I pasted a URL into the text box to test it, and within seconds, it generated a properly formatted citation.

It functions just like other citation generators, making it an excellent tool for students, researchers, and writers. If you’re working on a school report or research paper, this feature can save time and effort.

With QuillBot AI, you get all your writing and citation tools in one place, making it a complete writing assistant.

8. QuillBot Flow

QuillBot Flow integrates all writing tools in one place, making the entire writing process seamless. It features Smart Start, which helps users kickstart their projects effortlessly.

For example, if I need to write an essay on “The impact of climate change on global agriculture,” I enter the topic into QuillBot Flow, which quickly generates a detailed outline.

This tool isn’t just for essays, it works for blogs, research papers, and reports. By providing a structured outline, it helps users organize their thoughts and streamline content creation.

With QuillBot Flow, projects become more efficient. You can create a new project, then paraphrase, cite sources, and check for plagiarism, all from a single platform, eliminating the need for multiple tools.
