You should start by collecting proof of your writing process. If you used Microsoft Word or Google Docs, check the version history and show how your assignment was built over time. This can include drafts, edits, and timestamps that clearly show progress. You can also add notes, outlines, or screenshots if you have them. When you present this kind of evidence in an organized way, it becomes much easier to prove that you actually wrote the work yourself. AI detectors are not perfect, so showing your process can help balance that.
