A few AI humanizers can produce text classified as human, but they make the writing clunky and lower quality; most do not work reliably.
ChatGPT is a general-purpose AI assistant that can generate movie ideas and expand them into story and storyboard prompts. It can also produce software projects from natural-language prompts, such as a Python dating application with user profiles and swiping logic, and help explain electronics and hardware-development concepts. It is also cited as a general-purpose AI capability that consumer products can package into more personal, character-based experiences.
Clever AI Humanizer is described as a tool that humanizes test text before the text is evaluated by GPTZero. The available evidence does not specify its developer, interface, distribution, or implementation.
GPTZero is an AI-detection service for assessing whether text was written by a person or generated by an AI system. Its website offers an AI score and sentence-by-sentence detection for pasted text, including text associated with ChatGPT, GPT-5, and Gemini.
Grammarly is an AI writing assistance service that provides personalized guidance and text generation across apps and websites. In the cited video context, it is used to rewrite or humanize text before the text is checked for AI signals.
QuillBot is an AI writing tool that rewrites or humanizes AI-generated text. In the cited video context, it is used to modify text before the text is tested by GPTZero.
Turnitin is an academic integrity service that detects suspected AI-generated writing in student documents. The videos discuss false-positive results and the importance of preserving document drafts when using its detection results.
An AI text humanizer from UndetectedGPT that transforms AI-generated text into writing described as natural and undetectable by AI detectors. The service claims to bypass detectors including GPTZero and Turnitin and offers free humanizing.

00:00 I spent about 20 hours researching a humanizers and it's really bad. Most of them don't work and the few that do work unfortunately come with a price. They create their own problems too. And then if you're really good at writing yourself, then you can still get detected as AI simply because you write very well. So I will show you a solution to that.
00:24 I'll show you the problems and the solutions and what you can potentially do. First of all, to check if AI humanizer works, you need to have an AI detection system that you trust. So, I ended up working with GPT0 here. And this is a text I created and it shows as human 100% human. And then I have this text here which was generated by chart GPT. And it comes with 100% AI.
00:48 So, we have a positive and a negative control. So, it seems fine. And what I will try to do now is to humanize this text. So this is Quillbot and it comes as 100% AI unfortunately. Then we have humanized AI. This is a mix of AI and human. So it's also a fail. Then this is grammarly.com comes as AI as well unfortunately. This is clever humanizer again all AI.
01:12 And now we have humanizer.com. And this is coming as human which is what we want. And I will leave a link in the description down below to this AI humanizer. But the problem here is that once you start reading this text, it's bit clunky. It's a bit weird. Especially the sentence that I highlighted, it also means investing wisely, protecting with wills and more.
01:37 What is that about? So the point is that this AI humanizer is making the text human by introducing mistakes by essentially lowering the quality of your written English. And that's how they get away from AI detection. And then we have AI humanizer and it also is 100% human here. But again, you know, feel free to pause this to read this. It is a bit clunky.
02:03 It is bit weird. And I wouldn't write my name under this. I would want to rewrite this myself honestly. And then it got me thinking, am I the only one? Is this an inherent problem with the language that I'm testing? So I found this thread started by SPAL on Reddit. I will leave a link in the description down below. Honestly, it's really good and clearly SP spent hours and hours researching this as well.
02:29 And it just bags up what I'm trying to tell you here. He used all of these prompts to try to humanize text. using chat GPT and then someone else came and they added even more prompts and then they also tried so many different AI humanizes. There you go. We have a long list of some apps that they tried here and the bottom line is if they work they just make the language unusable just really clunky.
02:56 So there is no point using any of them because they just make the language clunky and weird and you will have to rewrite it yourself anyway. So was the point. But then on the other hand, what if you write very well, right? Especially if you're writing something formal and academic, what is going to happen? And guess what? I found my own text to be detected as AI generated.
03:20 So again, I went back to Reddit to see if anyone have a similar problem. And this person here is having exactly the same issue with 80% of the actual writing being detected as AI. And there's few other people in the post here talking about the same issues. So this is clearly a common issue even with turn it in that is used by all the major universities.
03:44 So if someone comes to you and says oh turn it in showed that your writing is AI generated but I think honestly the only way to prove that it's not is to show them previous versions of a document. So if you're writing a literature review, just keep saving different versions of the document. So then you can show them, look, I actually worked on this.
04:04 This is my own work. Because right now, this is clearly just numbers game. And if something is very well written, well, it must be AI. If it's not well written, then it's human.
