Plagiarism isn't always intentional. Whether you're a student trying to meet deadlines, a researcher compiling references, or a professional summarizing content, unintentional plagiarism can still happen, and the consequences can be serious. That's where tools like the Quillbot Plagiarism Checker come in. But with free vs. paid options and AI-generated content complicating detection, you might be wondering: Is Quillbot enough? And how can you really make sure your content is original?
In this guide, I'll walk you through exactly how to use Quillbot's checker, what its pricing looks like, and introduce a powerful (and free) alternative, WPS Office's Undetectable AI Rewriter, to make your writing sound human, professional, and pass AI and plagiarism checks.
Part 1: What is Plagiarism and the Need for Detection
Plagiarism is more than just copying and pasting someone else's words; it's about presenting another person's ideas, research, or phrasing as your own without proper credit. Whether intentional or not, plagiarism can lead to severe consequences in academic, professional, and even legal settings.
In academic writing, especially, maintaining originality is not just about ethics; it's about credibility. A single overlooked citation or poorly paraphrased sentence could flag your entire document. That's why plagiarism detection tools like the Quillbot Plagiarism Checker have become essential for students, educators, and professionals alike.
I've personally seen how easy it is to unintentionally commit plagiarism, especially when juggling multiple sources or using AI tools to help draft content. That's why having a reliable checker, one that can catch overlooked issues and offer detailed reports, is a game-changer. Not only does it highlight duplicated sections, but it also provides insight into how you can revise them responsibly.
Part 2: Quillbot's Plans and Pricing
Before diving into how to use the Plagiarism checker Quillbot offers, it's important to understand what features are included in their free vs. premium plans. While Quillbot is known for its paraphrasing tool, plagiarism detection is only available with a Premium subscription.
Free Plan:
The Quillbot Plagiarism Checker free version includes:
Basic grammar checking
Limited paraphrasing features
No access to the plagiarism detection tool
It's a solid option for quick edits and minor rewording, but if your goal is to verify originality, this plan won't be enough.
Premium Plan (Required for Plagiarism Checker):
To unlock the full capabilities of the Quillbot Plagiarism Checker, you'll need a Premium plan. Here's what you get:
Full access to the Plagiarism Checker
All 7 rewriting modes (including Academic, Creative, Formal, etc.)
Unlimited grammar checks
Enhanced word limits and faster processing
As for the Quillbot Plagiarism Checker price, here are your options:
Monthly: $9.95/month
Quarterly: $6.65/month (billed $19.95 every 6 months)
Annual: $4.17/month (billed $49.95 per year)
In my experience, the annual plan offers the best value if you're writing frequently or working on long-term academic or professional projects. However, for short-term needs like a single research paper or thesis, the monthly plan might be more practical.
Part 3: How to Use Quillbot Plagiarism Checker to Avoid Plagiarism
Now that you understand the pricing plans let's walk through how to actually use the Quillbot Plagiarism Checker to ensure your work is original and citation-safe.
Step 1: Get a Subscription
Visit Quillbot's pricing page and choose a plan based on your writing needs. You'll need a Premium subscription to access the plagiarism detection feature. If you're writing a thesis, academic paper, or professional report, I highly recommend going for at least the monthly plan to make the most of the checker.
Step 2: Access the Plagiarism Checker
After subscribing, navigate to the Plagiarism Checker via your dashboard or go directly to quillbot.com/plagiarism-checker.
The interface is clean and easy to use, even for first-timers.
Step 3: Upload or Paste Your Text and Scan for Plagiarism
You can either paste your content directly or upload a .doc/.docx file. I usually paste the content to get instant feedback and tweak things on the go.
Step 4: Review the Report
Once your text is analyzed, Quillbot will highlight any potential matches found across the web or academic databases. It provides a similarity percentage and shows exact lines that may need revision or citation.
Step 5: Revise and Re-run the Check
Use the insights from the report to add missing citations, rephrase flagged sentences, or simply delete copied text. You can re-run the checker after each revision to ensure your document is clean and plagiarism-free.
As a tech writer, I find the Quillbot Plagiarism Checker surprisingly intuitive. The color-coded report makes it easy to see problem areas, and the percentage breakdown helps you know exactly how much content might raise red flags. That said, it's not perfect sometimes; it catches generic phrases as plagiarism, so using your own judgment is still important.
One limitation is that the tool doesn't always do well with AI-generated text, especially when it's paraphrased. That's why, in the next section, I'll introduce a free and powerful tool, WPS Undetectable AI Rewriter, that works beautifully alongside Quillbot to make your writing even more original.
Part 4: Best Alternative AI Checker to Quillbot: WPS Undetectable AI Rewriter
While the Quillbot Plagiarism Checker is excellent for spotting direct overlaps with online content, it's not always enough, especially when dealing with AI-generated drafts or paraphrased material that still feels robotic. That's where the WPS Undetectable AI Rewriter shines.
This tool is designed to take AI-generated or paraphrased content and transform it into natural, human-sounding text that can bypass not only plagiarism detectors like Turnitin but also AI detectors such as GPTZero and Originality.ai. And the best part? It's completely free to use, no account is needed, and there are no limitations.

Key Benefits of WPS Undetectable AI Rewriter
Humanized Rewriting to Reduce Plagiarism Risk
Instead of simply swapping out words, this tool restructures sentences in a way that sounds natural and original. This minimizes the risk of plagiarism while keeping your core message intact.
Multiple Writing Modes for Different Needs
You can choose from four rewriting styles:
More Human – Best for general content
Academic – Ideal for formal essays and scholarly articles
Simple – Useful for easy-to-read blog posts or instructions
Professional – Tailored for business and technical documents
I often use the "Academic" mode when finalizing research papers. It gives the writing a polished, credible tone without sounding robotic.
Ideal for AI-Assisted Drafts
If you're like me and occasionally use ChatGPT or other AI tools to draft ideas, the WPS AI Rewriter helps smooth out the language to sound more like your natural voice.
Free, No Login Required
You can simply paste your content, select a mode, and hit rewrite, but there is no sign-up or payment.
Bypasses Common Detectors
I've tested it against multiple platforms, including Turnitin and GPTZero, and it does a solid job at flying under the radar. It's not foolproof, but it significantly improves your chances of avoiding false positives for AI or plagiarism.
After running my content through Quillbot and fixing the major flags, I often do a final polish with the WPS Undetectable AI Rewriter. This two-step approach, first checking for direct matches and then refining the language, has helped me maintain originality while still writing efficiently.
Part 5: FAQs about Quillbot Plagiarism Checker and WPS Undetectable AI Rewriter
Q1: Can Quillbot guarantee a 100% plagiarism-free result?
Not exactly. While the Quillbot Plagiarism Checker is highly effective in identifying direct matches, it may not catch everything, especially if the content is heavily paraphrased or comes from niche sources. I always recommend reviewing the flagged sections manually for better accuracy.
Q2: Is Quillbot enough to beat Turnitin?
In my experience, Quillbot helps reduce the risk of plagiarism, but Turnitin is incredibly thorough. It may still flag AI-written or overly similar content, even if it's paraphrased. For this reason, using a tool like the WPS Undetectable AI Rewriter alongside Quillbot adds a stronger layer of protection.
Q3: Is WPS's AI Rewriter free?
Yes, it is completely free, with no need for an account or subscription. You can use it directly in your browser without limitations. For anyone working with tight budgets or on-the-go edits, this is a major advantage.
Q4: Which tool should I use for academic writing?
Both! Use Quillbot to check for direct plagiarism, then refine your work using WPS's "Academic" rewriting mode to make your content sound more natural and scholarly. This dual approach has worked wonders for me during thesis submissions and peer-reviewed publications.
Summary
Plagiarism is a serious concern, whether you're a student, educator, or content creator. And while the Quillbot Plagiarism Checker does a great job detecting copied or closely matched content, it's only part of the solution.
For content that's AI-assisted, overly paraphrased, or just needs to sound more natural, the WPS Undetectable AI Rewriter is the perfect companion. It doesn't just "rewrite". It humanizes your content, helping you bypass AI and plagiarism detectors while keeping your message clear and professional.
As someone who values both originality and efficiency, I've found that using both tools together gives me the best results. Start with Quillbot to catch what's already out there, then refine your content with WPS's free, user-friendly tool.
By combining detection and intelligent rewriting, you can confidently submit original, high-quality work every single time.
