AI Detection in AH Physics Project

Hi all,
I finished my advanced higher physics project this week and am going on to print it now. When re-reading it, I realised how the professional tone I used in project sounds a bit robotic, and was scared that the markers might think I used AI. When I put it into a few AI detectors, it said that my project was like 78% AI. I know everyone says these things are very unreliable, but I am really paranoid and don't want to get flagged for AI use. Should I change the way it sounds?

If you didn't use AI you are fine.
Stop putting work in "AI detectors" which are just as often unsecured AI agents themselves which will just make up random junk to say back to you, and may also train their model on your work which could then be regurgitated for someone else and be submitted and end up creating potential issues about plagiarism.
AI isn't something your work can "catch", it's not an infection. It's a conscious choice to use a tool which you are usually being instructed not to use, an hence commit academic misconduct. If you did not do that you have nothing to worry about, end of story.
