Sorry for late reply Juan. We have a set of algorithm to detect plagiarism, however nothing can be perfect. AI itself is AI because it's artificial, it need human to feed in the data so it can process. But when an AI can do it's own determination without human input, Houston we have a problem.
Can you imagine when a script can automatically scan for articles on the internet,
Automatically download pictures with the similar tag category from the internet, crop the pictures, apply shades and tilt the picture a little so the source code arrangement of the picture will also change arrangement
Automatically arrange the wordings like grammar checker, to make sure the meaning remains but the word being used become different.
And finally, automatically make a post with all the rearranged text, newly photoshopped photo, run a set of tags and posted in the frontend.
All these can be done automatically. So, imagine if you have an AI plagiarize checker, the next thing is someone use the AI checker algorithm reverse it, and you have an AI plagiariser automatically post spinned article everywhere everyday🤣
