While I strongly believe that AI in general and AI content generator tools in particular are a boon to most writers, there are times when you don’t want to use them. One such considerable case regards the risk of plagiarism. Obviously, plagiarized content is not acceptable in both academic and web writing.

Perhaps unsurprisingly, the answer is given by another AI tool, that of AI content detector tools. These can be a great professional aid to avoid legal penalties for using plagiarized content.

Most such tools are equipped with the advanced GPTzero technology developed to identify machine-generated text.
