What is QuillBot?

If you’ve ever stared at your screen, struggling to find the right words or double-checking your content for grammar issues or plagiarism, let me introduce you to a tool that might just become your new writing sidekick: it’s known as QuillBot.

A Quick Look at the Background

QuillBot didn’t just appear out of thin air. It was developed with a clear mission: to make writing easier, faster, and smarter using the power of AI. What started primarily as a paraphrasing tool has now grown into a full-fledged writing assistant trusted by students, bloggers, professionals, and content creators around the world.

Over the years, QuillBot has evolved beautifully. From just rephrasing sentences, it now helps users polish grammar, summarize articles, generate citations, and yes, detect plagiarism. It’s like having an intelligent editor in your browser or desktop, ready to help at a moment’s notice.

Core Features That Make QuillBot Plagiarism Checker Stand Out

Let me quickly walk you through the core tools that make QuillBot such a powerhouse:

Paraphraser: This is QuillBot’s bread and butter. Whether you want to reword a sentence to avoid redundancy, improve clarity, or just sound more professional, this tool has multiple modes (like Standard, Fluency, Formal, etc.) to match your intent.

Grammar Checker: Typos and awkward phrasing? Not anymore. The grammar checker automatically corrects your content and suggests improvements, so you sound sharp and credible.

Summarizer: Need to digest a long article or research paper into a few key points? The Summarizer helps you break down the gist without losing essential meaning and is perfect for students or researchers on a deadline.

QuillBot’s Plagiarism Checker: This is one of my personal favorites. Whether you’re writing academic papers or blog posts, the tool scans your content across billions of sources to ensure it’s completely original.

And the best part? These tools work seamlessly together. You can paraphrase, check grammar, and scan for plagiarism all in one place.

How QuillBot Plagiarism Checker Works: Step-by-Step

Using QuillBot’s plagiarism checker is straightforward and designed to save you time. Whether you’re a student, writer, or professional, these simple steps will help you quickly scan your content for originality and ensure it’s plagiarism-free. Let’s walk through the process together.

1. Access the Plagiarism Checker in Your QuillBot Premium Account.

To get started, you’ll need to log in to your QuillBot account with a Premium subscription. For demonstration, I selected the monthly plan to get started.

The plagiarism checker is one of the premium features, so it won’t be available on the free plan. 

Once you’re logged in:

• Head to the main menu or dashboard.
• Look for the “Plagiarism Checker” tab—it’s clearly labeled and easy to find.
• Click on it, and you’ll be taken straight to the tool’s interface.

No software installation or tricky setup is needed; it all runs smoothly in your browser.

Pro Tip: Bookmark the checker page so you can jump right into it for future scans.

2. Paste Your Text or Upload a Document

Now that you’re in the tool, it’s time to bring in your content. QuillBot gives you two flexible ways to add your text:

• Copy-paste: Simply paste your content directly into the text box. Perfect if you’ve just written something in Google Docs or another editor.
• Upload a file: Got a saved document? Upload your .doc, .docx, or .pdf file straight into the tool.

As you can see in the image above, I simply copied and pasted one of my blog posts to check for plagiarism in my content.

Whether it’s an essay, blog post, email draft, or marketing content, this step works seamlessly no matter the format.

Pro Tip: If you’re working on multiple pieces, you can run them one at a time to manage your monthly word limit.

3. Start the Plagiarism Scan

With your content in place, go ahead and click the “Scan Text” button. QuillBot’s AI instantly begins scanning your text against a massive database of billions of online pages, including:

• Websites
• Articles and blogs
• Academic journals
• Research papers
• Public databases

So, I pasted 2,000 words into QuillBot’s plagiarism checker just to test its speed, and guess what? It scanned the entire content in just 1 minute and 2 seconds! That’s insanely fast, and honestly, I was seriously impressed.

The entire process usually takes just a few seconds, depending on the length of your content. No lag, no loading screens, just fast, efficient scanning.

Pro Tip: The tool also supports scanning in over 100 languages, so you can check multilingual content too.

4. Review the Plagiarism Report.

Once the scan is complete, you’ll receive a detailed and easy-to-understand plagiarism report. As you can see in my results, the content showed a plagiarism score of 5.5%, which clearly means a few areas need editing to ensure it’s fully original.

Moreover, you’ll notice the results on the right side of the report, where it shows the exact websites our content matched with. These are the areas we need to review and correct to make the content fully plagiarism-free.

On the left side of the report, you’ll see color-coded yellow highlights marking the sections where matches were found. To make your content completely plagiarism-free, you only need to revise those specific sentences.

This isn’t just a technical report; it’s a clear, visual breakdown of your text’s originality. It helps you instantly spot which parts need editing, rewriting, or citations.

Pro Tip: Don’t panic if you see small matches. Common phrases or citations might show up; focus on the longer or heavily matched segments, which I highlighted in the above image.

5. Check Sources and Make Edits

This is where you fine-tune your work. Click on each highlighted section to see where it came from. Then decide:

• Should you rewrite or paraphrase this part?
• Does it need a proper citation?
• Is it a common phrase that can be left as is?

QuillBot makes it easy to verify and clean up your content without second-guessing. You’re in control of the changes, and the feedback is practical, not overwhelming.

Pro Tip: Pair this step with QuillBot’s Paraphraser tool for quick and accurate rewrites without losing meaning.

6. Re-Scan to Confirm

After spotting the plagiarized lines, I went ahead and edited those specific sentences. Then, I ran a second scan, and guess what? The final plagiarism score dropped to just 0.6%, which is totally acceptable!

This second scan confirmed a few important things:

• All previous matches were either removed or properly cited.
• The content is now 100% original.
• I’m fully ready to submit, publish, or share it with confidence.

Honestly, many people skip this step, but it’s one of the most crucial parts of the process, especially if you’re turning in academic work, client projects, or publishing online. A final scan gives that extra peace of mind you didn’t know you needed!

Pro Tip: Save a copy of your clean plagiarism report; some schools or clients may require proof of originality.

Want to Scan Another File or Revisit an Old One? QuillBot Makes It Easy!

Once I finished checking my first file for plagiarism, I wanted to scan a new one, and guess what? QuillBot makes that super simple. Just click the “New Scan” button to start fresh with a new piece of content. No need to reload the whole tool again; it’s quick and smooth.

And if you want to revisit any of your previous plagiarism checks, you’re covered there too. Just tap on the “Previous Scans” option (you’ll find it right at the top-right corner of the screen). So, there’s no need to worry about losing any of your old reports. They’re all neatly stored and just a click away.
