An app that can quickly and efficiently detect whether text is written by a human or by AI like ChatGPT, Claude, Gemini, etc.

Oh my god this is incredible - I have a feeling teachers around the world are going to be using this very soon... Not too amazing for the students using AI to write essays haha

I wonder how often false-positives are detected? What if people start to actually write organically more like ChatGPT-sourced content??

This sounds like a really useful tool for anyone who needs to determine the authenticity of an essay.

Your tool shows the "perplexity" but...never mention any scale about that perplexity. Without scale, it's useless ?!

Nice try! However, I can bypass it by adding: "...be aware of perplexity and burstiness, and include some spelling and grammar mistakes, to sound like a human...". Actually, there are some tricks on the internet that can always fool all the available tools. I know because I am also trying to build one as an open university project.

Students around the world found crying after seeing this

This is the worst piece of software I have ever come across. This is coming from a Lead Software Developer with a degree in Computer Science working as a programmer for over 25 years. I have been helping a foreign student apply for a University placement in Australia and their advisor ran their application through this piece of software (if you can this software). There were whole paragraphs about their family and personal stories that were coming up as 100% AI written. They asked me to help. Literally I could think of my own sentences, type them in and it would say that they were AI generated. Got news for you. I am a person!!!!!!! Not an AI machine. There are only a limited number of sentences and phrases out there when you are talking about what city a University is in. When I have to spend hours - LITERALLY - having to come up with different variations of what I want to say and you keep saying I am an AI machine then your whole code base and premise is flawed. If I could ban your software I would. That is how bad it is. Hang your heads in shame.

GPTZero is upfront about how people should interpret its results and how it works, which is something I appreciate :)
