Originality AI left me very disappointed. I used both their website and Google Chrome extension, and I tried with the 50 credits they give you for signing in. I scanned tree documents: one entirely produced with AI, another completely original. Also, I tried some weird text I created in the moment about my day. All showed a horribly 99% AI generated content and and 1% of non-original human content. In the first text, it was understandable, but the second and the third were all false positives. Recently, I read a blog post from them about false positives and how to read them. They say that Originality AI only demonstrate "probabilities", but also say their tool is the most accurate in the market. Honestly, I prefer to identify manually the AI generated content by checking plagiarism, do fact checking, identifying patterns, and ask writers to create their content in Google Docs. Don't waste time and money there.
