Do free, AI/plagiarism detectors keep or redistribute work? Please help

If it’s entirely your own work then there is no point using these services. None.
Going back to the original question, yes they might, by accident or design, which is why we spend so much time on TSR telling people to avoid using them.

reading this after i just done the same thing🥲

Basically for context, a couple days ago I've written a draft of both my personal statement for UCAS and an essay plan of my coursework in my own words, I scanned them through less used and known websites such as "plagiarismchecker.ai" and "freeaitextclassifer.com" and a couple others and they are free, I was worried my personal statement will get flagged by UCAS so I used them to scan my work to reassure myself. It was such a dumb idea and I later found out that these free ai/plagiarism detectors are unsafe and sketchy, and I'm now going down a rabbit hole. Apparently these AI detectors could use people's work and send them to essay mills for profit or online for people to see? I found reddit posts about people's work being uploaded to websites like Bartleby without their consent and their work is there, and some were unable to take it down. My concern is that when I finally submit my UCAS personal statement it'll be flagged as a 100% match if it was uploaded online, and my applications would be rejected, and I can't appeal and my future will be over 😭. I was supposed to spend my halloween break revising for my Winter exams, but I spent the previous few days stressing over this. I tried to reason with myself that it's fine, but then every once in a while, a random doubt pops up and I start panicking again.

Hi @VHxted1 ,
Firstly, talk with your Sixth Form staff. Explain your situation and that it was an oversight and hopefully they can give you some accurate advice.
Also, as long as you have not used AI, then you should not need to put your work through a checker. These can be unsafe, especially on free websites. Generally, avoid copying and pasting any work into AI unless you have specifically been allowed to.
Try not to panic, you should be fine just communicate this issue with your sixth form staff.
I hope this helps, please feel free to ask me any questions,

I'm not that active on TSR, but honestly I think I should've been more careful with these kind of tools. Should I change anything regarding my personal statement? My concern is that if I change everything on my personal statement then I have nothing really else to write because I have put everything onto the first draft, and in the case my thing was posted online somewhere I can't put anything else down.
