Details About The quillbot ai detection tool
What is this system? A smart text scanner. The tool looks for patterns in your words. It checks how predictable your sentences are. I pasted an essay into the box. I wanted to see the magic.
The results come back in three seconds. A green check or a warning appears. It is very simple to use. Plus, it gives you a clear score.
Sentence Level Scans
This feature is my favorite. The system looks at every single sentence. It does not just grade the whole page. On top of that, it highlights bad sentences for you.
You can rewrite the bad parts easily. However, you must be careful. I noticed it can make mistakes. We will talk about that later. True story.
Real Data From The quillbot ai detection tool
I love numbers. I wanted to see hard data. I read a study from Robert Morris University. Researchers tested one hundred text samples. They used human text. They used machine text too.
The quillbot ai detection tool caught all 34 machine samples. That is a one hundred percent success rate for robots. I was very impressed by that number.
On the contrary, it marked human text wrong sometimes. In another test, it flagged thirteen percent of human text as machine text. False alarms happen. Bad news, right? Yes.
I created a table to show you the accuracy rates. The data comes from various recent tests. You can see the numbers clearly below. This helps you understand the true power of the software.
| Test Source | Machine Caught | Human Flagged By Mistake |
| University Study | 100% | Very Low |
| Netus AI Review | 71% | 13% |
| Journalist Tests | 80% | Moderate |
Costs And Plans For The quillbot ai detection tool
Business owners always ask me about costs. I care about my budget too. You can use the basic scanner for free. You just paste your text on the website.
However, the free plan has limits. You can only check 1,200 words at one time. Additionally, you get six scans per day. This is fine for small tasks.

I built a pricing table for you. It compares the free option and the paid option. You can see the exact features side by side. Choose the one that fits your budget.

Should You Trust This Tool?
This is the big question. My answer is yes and no. The system is a good starting point. It catches lazy robot text very fast.
Though, you should not rely on it completely. I tested it last year. At that time, I saw it fail against advanced robots like GPT-5 and Claude 3. It missed highly edited text.

- It is fast and free for short text.
- It highlights exact sentences for you.
- It makes false accusations against human writers.
