r/content_marketing on Reddit: How reliable are AI detectors?
August 11, 2023 -
Since OpenAI pulled the plug on their AI Text Classifier stating that it wasn't able to detect AI text properly there has been a ongoing debate whether these AI detectors are at all reliable or not.
Now I have my own opinion on this matter but before sharing that let me share some statistics
Studies have been made to test the accuracy of these AI detectors several times and here were some of the findings -
- These detectors often labeled non-English writings under AI-generated even if the content was human-written.
- Most detectors were able to have a 60% or less accurate detection of any type of content.
- Much research also shows tests involving SICO-generated content could easily bypass AI detectors to get a human written verdict.
- Paid AI detectors have a significantly higher accuracy rate but it is still at about 80%.
- AI detectors much like AI tools can be biased in certain scenarios.
My take on the matter
I have used a fair share of AI text detectors including OpenAI's AI Classifier (when it was still available) and to be honest they are quite questionable. It is now quite safe to say AI content is becoming more precise and humanlike which cannot be easily differentiated.
Still, when I see unedited answers copy pasted to Reddit and other communities from ChatGPT it is quite easy to detect without any AI detector.
Having said that I don't think taking help from AI tools to enhance your writing is bad rather I encourage you to do so as it improves the quality of your writing tenfolds.
Do you use AI to create written content? Do you think AI detectors should be more accurate?
Let me know in the comments below.

August 11, 2023How Reliable Are AI Content Detection Tools?
No AI tool is 100% correct. I have tried ZeroGPT, contentatscale, Copyleaks, Quetext and more. Many have false positives. Some even detected my old written content from 7 years ago as AI lol, which is hilarious. So, based on that, now I don't give a shit about detection lol. I mainly focus on the quality, user-focussed content and SEO. If a content is ok on the basis of these three factors, then its good to go. I have tested it as well and got pretty good results.

I just want to make sure I understand this. It said that your write was 100% generated, but then when you used the tool to generate a paraphrasing of your own text it said it was now only 58% generated? Seems a bit backward to me. To answer your question, none of the current AI detectors are any good at all. Just do your own work, and if it is ever questioned, there are plenty of articles that you can use to fight your case.

August 17, 2024What Are AI Detection False Positives?
False positives do occur and can be painful. At Originality.ai, based on our accuracy study, our Lite model has a 0.5% false positive rate, our Turbo model has a 1.5% false positive rate, and our Academic model has a <1% false positive rate.
The AI researchers and machine learning engineers at Originality are working constantly to both improve detection accuracy and reduce false positives.
We are heavily focused on equipping writers with tools to help them prove their content’s Originality, which is why we developed a free Chrome Extension that allows anyone to visualize the creation process of a Google Doc. Watch our Chrome Extension tutorial!

When Turnitin activated its artificial intelligence detector in April 2023, it provided a substantial amount of nuanced guidance. The company did a laudable job of explaining the strengths and the weaknesses of its new tool, saying that it would rather be cautious and have its tool miss some questionable material than to falsely accuse someone of unethical behavior. It will make mistakes, though, and "that means you'll have to take our predictions, as you should with the output of any AI-powered feature from any company, with a big grain of salt," David Adamson, an AI scientist at Turnitin, said in a video.

I had to do an analysis on a fairytale, jack and the bean stalk and my teacher said my report sounded too formal and ran it through an AI detector, saying that 80% of it was likely AI. But the thing is, the AI was counting the questions which I stated and had to answer. I tried to disprove him saying that I didn't cheat, because I went ahead and plugged my essay into 4 other different kinds of AI detectors, all saying different things from 0 to 40%, meaning that AI is not a definitive way to show the proof of a students work.
