This machine learning approach allows it to recognize the distinctive patterns that characterize AI-generated text versus human writing.
It analyzes linguistic markers, including word choice patterns, sentence structure consistency, and stylistic uniformity, to detect AI authorship.
Based on its analysis, the detector then provides a confidence score indicating the likelihood that the text was produced by an AI system.
Is the Scribbr AI Detector Accurate?
Now, the question at the top of your mind is, how accurate is Scribbr AI detector?
You can try to detect AI content yourself, however, you won’t be as good as an authentic AI detector, as these AI tools are getting better.
Naturally, we thought of this and have crafted an industry-tested and standard test to determine how accurate the Scribbr AI detector is.
Using ZDNet’s widely accepted benchmark testing and our first-hand tests, we’ve gotten a clearer picture of Scribbr AI detector’s capability to present you with an unbiased opinion before trying out this tool.
Importantly, ZDNet has also tested our AI detector compared to 9 others and found ours to be 100% accurate in detecting human and AI content.
So, is Scribbr AI detector accurate?
Let’s use Scribbr and see how well it does.
The Test
To test the Scribbr AI detector, we created AI content via ChatGPT, a prominently used AI tool.
We then ran the AI content via Scribbr and Undetectable AI Detector to see which of the two tools can accurately detect whether it’s AI-generated content.
In this test, we ran AI content through Scribbr AI to test its accuracy. For added confirmation, we also used our AI detector for the same tests.
The Results
These are the results of the tests based on two given scenarios.
Cover Letter
ChatGPT Generated Content:
Based on ChatGPT’s output, here’s what Scribbr AI detector found.
Scribbr AI Detector Score: Scribbr accurately notes the content to be 100% AI.
Undetectable AI Score: Our detector also found it to be 99% AI, but with a 1% margin of error.
Essay Excerpt:
This essay excerpt was human-written, but we’ve used AI to improve the text to increase the testing difficulty. Here are the results:
Scribbr AI Score: Unfortunately, Scribbr didn’t find any trace of AI. Hence, its assessment of 0% AI is flawed.
Undetectable AI Score: Running the same text through our detection shows a 95% AI likelihood. This is a more accurate measure to go by.
From the results, although Scribbr AI detector can detect AI content from ChatGPT, when it comes to human written AI improved text, it fails to accurately note whether the content could be AI-influenced.
This leads us to conclude that it’s not as rigorous as undetectable AI detector, which can accurately highlight areas where there is AI content, even if it is in human-written texts.
So, to find out if your written content will be flagged as AI content across multiple detectors and not just Scribbr, use our AI Detector and Humanizer.
With this tool, you can effectively convert an AI-generated text to sound like a human-written one, with a natural tone and flow.
