With more people relying on tools like ChatGPT, Jasper, and other AI writers, it is becoming essential to differentiate between human-written and AI-generated text. QuillBot, known for its popular writing tools, has introduced an AI Detector to solve this problem. However, Is QuillBot AI Detector accurate? In this article, we will dive into how QuillBot’s AI Detector works, its key features, and whether it can deliver accurate results.
What is QuillBot AI Detector?
QuillBot has introduced a new feature called the AI Detector, which can determine whether content is written by a human or generated by artificial intelligence (AI).
This free tool is useful for educators, content creators, and businesses to verify writing authenticity. Users can analyze up to 1,200 words at a time without needing to sign up or create an account.
How Does It Work?
“We don’t just identify text generated with AI tools such as ChatGPT, Gemini, and Claude. We also analyze text refined with paraphrasers or grammar checkers—including our own.”
The QuillBot AI Detector uses advanced machine learning to examine the structure, tone, and style of a piece of text. It compares these features to known patterns of AI-generated content. This helps the detector decide whether a human or an AI likely created the text.
- Language Patterns: AI-generated content has a unique structure (repeated words, awkward phrases, and unnatural flow) that differs from human writing, which the AI detector identifies.
- Consistency: AI writing is more consistent in tone and word choice, while human writing varies with context and emotion.
- Complexity: The tool checks for sentence and vocabulary complexity, as AI often uses simpler sentences.
Key Features of QuillBot AI Detector
- Ease of Use: The detector is user-friendly. You simply paste your text into the tool, and it gives you a quick result-human or AI-generated.
- Speed: Results are provided almost instantly, making it a fast solution for users who need immediate feedback.
- Accuracy Insights: While no AI detector is 100% accurate, QuillBot claims to offer a highly reliable solution, though the accuracy can vary depending on the type of text being analyzed.
- Versatility: The tool is suitable for many users, including students, teachers, content writers, and businesses, who want to ensure their content is original or identify AI-written materials.
QuillBot is also committed to continuously improving the accuracy and effectiveness of its AI detection tool. The company regularly updates and refines its technology to stay ahead of the latest advancements in AI writing, ensuring the detector becomes more reliable over time.

Is QuillBot AI Detector Accurate?
QuillBot AI Detector accurately identifies AI-generated content in simple texts but may struggle with complex or heavily edited ones. Well, that’s understandable because no detector is 100% reliable.
Still now, there is no survey or research available regarding the effectiveness of QuillBot AI Detector. From our investigation, only Scribbr claims that the QuillBot AI detector has an accuracy rate of 78% in identifying AI-generated content. However, users on Reddit report very different experiences with the detector.
Some users mentioned that it incorrectly flagged human-written content as AI-generated, while others noted that it failed to recognize certain AI-generated text.
Because of those conflicting opinion, we are here to conduct a test and help you have your own answer if QuillBot AI Detector is reliable. Let’s jump right in!
How Accuracy is QuillBot AI Detector? Our In-Depth Test Results
1. Our Tested Process
Our Test Plan to Evaluate QuillBot’s AI Detector:
Step 1: Gather two paragraphs, including:
- AI-generated text from different AI models (ChatGPT-4).
- A human-AI mixed paragraph from an AI humanizer.
Step 2: Run each paragraph through QuillBot’s AI Detector, Undetectable AI, and Originality AI to confirm QuillBot’s accuracy.
Step 3: Summarize the results.
2. The Results
First, we put a prompt to ChatGPT to get a short paragraph about global warming.
Then, we paste it into the QuillBot AI detector to see if it can identify AI-generated text.
QuillBot AI Detector definitively shows that this content is entirely generated by AI!
What about mixed human-AI text? We used a humanization tool to enhance the AI-generated text from ChatGPT-4.0 above, and let’s see if QuillBot can bypass this text.
The tool indicates that the content is generated by humans. Is the AI humanizer tool genuinely effective, or is the QuillBot AI detector incorrectly identifying it? To find out, we utilized two additional best AI detector tools that are widely trusted by educators for their accuracy: Undetectable AI and Originality AI. Let’s review the results below:
And here is the result from Originality AI:
| AI Detector | AI Text Detection | Mixed Human-AI Text Detection |
| QuillBot AI Detector | 100% AI-generated | 100% likely human |
| Undetectable AI | AI-generated | AI-generated |
| Originality AI | 100% AI-generated | 74% likely AI |
QuillBot marks fully AI-generated text as “100% AI-generated.” It rates text that mixes AI and human contributions as “100% likely human,” which suggests it may be biased toward detecting human input. This can lead to false positives. Undetectable AI labels both fully AI-generated and mixed text as “AI-generated,” showing it is very good at spotting AI content. However, its reports are not as detailed as those from Originality AI.

Conclusion
In conclusion, QuillBot AI Detector is a reliable tool for detecting AI-generated content. It works well for simple texts created by common AI models. However, its accuracy may drop when dealing with more complex or heavily edited AI content. If you’re looking for an AI writing tool that includes an AI detector, Undetectable AI is a must-try. For an AI detector, Originality AI is definitely the best option, without a doubt.
FAQs
It depends on the specific context. While Undetectable AI is designed to make AI-generated content harder to detect, QuillBot’s AI Detector is focused on identifying AI-written text, so each tool serves a different purpose rather than being definitively better.
QuillBot is generally reliable for paraphrasing, grammar checking, and summarizing, but its accuracy can vary with complex texts, often requiring further refinement for clarity.
QuillBot’s AI detector identifies AI-generated text, while Turnitin primarily checks for plagiarism but includes some AI detection features. Turnitin is more comprehensive for academic integrity, but QuillBot is faster and simpler for spotting AI content.
