DupliChecker AI Checker Review & Test: Can It Really Work?
With the rise of AI-generated content, tools like DupliChecker AI Checker have emerged to help users detect whether a piece of text was written by a human or an AI. But how accurate is it? In this in-depth review, we'll explore its features, performance, and whether it truly delivers on its promise.
What is DupliChecker AI Checker?

DupliChecker AI Checker is an online tool developed by DupliChecker.com, a well-known platform offering plagiarism detection and content analysis services. The AI Checker is designed to identify whether a given piece of text was written by a human or generated using artificial intelligence. As AI-generated content becomes increasingly common in academic, professional, and creative fields, tools like DupliChecker AI Content Detector aim to help users verify the authenticity and originality of written content.
Features of DupliChecker AI Checker
DupliChecker offers a variety of features aimed at helping users effectively detect AI-generated content:
- User-Friendly Interface: Easy to navigate and use.
- Text Submission Options: Supports direct input, file uploads, and links.
- AI Detection: Identify AI-generated text, though accuracy may vary.
- Quick Results: Provides fast feedback on content analysis.
- Free Trial: No registration is required to access Detection AI.
Testing Accuracy and Results
To evaluate the performance of DupliChecker AI Checker, we conducted a series of real tests using content generated by different AI models. The goal is to test how accurately the tool can detect AI-generated content when the input text content has a variety of styles.
We prompted five leading AI models including ChatGPT, Gemini, Grok, Claude, , and Deepseek with the same instruction:
"Help me generate a beautiful sentence describing Iceland's Aurora Borealis, about 1,000 words."
Each model produced a vivid, poetic narrative designed to emulate human literary expression. We then submitted the outputs to DupliChecker AI Content Detector to evaluate their detectability.
The results of AI detection of the content generated by ChatGPT:

The results of AI detection of the content generated by Grok:

The results of AI detection of the content generated by Claude:

The results of AI detection of the content generated by DeepSeek:

The following is a summary table of test results:
AI Model | Human Content Score | AI Content Score | Detection Verdict | Is It Acuurate |
---|---|---|---|---|
ChatGPT | 100% | 0% | Likely to be Human Written | ❌ |
Gemini | 100% | 0% | Likely to be Human Written | ❌ |
Grok | 99.9% | 0.1% | Likely to be Human Written | ❌ |
Claude | 100% | 0% | Likely to be Human Written | ❌ |
DeepSeek | 100% | 0% | Likely to be Human Written | ❌ |
Despite being entirely AI-generated, all five texts were classified as human-written, with scores ranging from 99.9% to 100% human. DupliChecker failed to detect any AI involvement in the outputs of the above 5 AI models. This points to a significant limitation in the tool's detection algorithm---especially when dealing with creative, descriptive, or emotionally rich content.
These findings suggest that DupliChecker AI Checker may not be reliable for detecting well-crafted AI content, particularly when generated by top-tier models and written in a human-like tone.

A Smarter Way to Make AI Content Undetectable
In today's academic landscape, an increasing number of students are leveraging AI tools to assist with their assignments, papers, and research abstracts.
