Apart from OPEN AI, there are other projects that offer free AI on a trial basis. I do not wish to reveal their names but the trick is to use them for free is just register using a different email address whenever the free period expires. These content writers are also very good and effective. If you think this behavior would get reduced then you are wrong. I say this because of my experience in the teaching profession I know how and through what my students have been submitting assignments.
But these systems have a lower quality level than OpenAI, making it easier to detect text created by AI. Now, of course, it will not eliminate this situation, but the fact that this system is paid now, will at least reduce the most difficult cases to detect.
