GPT-2 Output Detector — checks Ukrainian texts

[hasibaakterss3309]

While the service's algorithms are being trained under one AI model, an updated and more complicated version of the chatbot is already appearing, so the accuracy of the checks is not very high.
Proofreading programs are designed for English-language texts, so you should be cautious about the results of analyzing Ukrainian texts. And some of them do not recognize the Ukrainian language at all.
Here is a list of the most popular services:

GLTR v0.5 — does not recognize the Ukrainian language
GPTZero — gives an error when checking Ukrainian text
AI Text Classifier from OpenAI — checks Ukrainian-language texts
AI Content Detector — gives an error when checking Ukrainian text
For the experiment, I checked my own text in the GPT-2 Output costa rica telegram data Detector service: with a probability of 98.78%, it considers it real, that is, written by a human. And then I asked it to analyze the generated text: it guessed again, although the confidence is slightly lower — 92.07%.

And when I asked ChatGPT to analyze these texts and draw a conclusion about their origin, I received an unexpected answer. It rated the text I wrote as 50/50.
