Would my word doc be detected as ai written?

A user is concerned about their Master's thesis chapter being detected as AI-written. They composed the chapter entirely themselves in Google Notes, but then used ChatGPT to format it into a Word document with MLA style and add in-text citations. The user is worried that the document's creation method or the act of copy-pasting the content might trigger AI detection, despite the text being 100% their own original writing.
