I got flagged by an AI writing detector for a paper I wrote myself. What do I do?

[Disser]

I'm freaking out right now. My professor emailed me saying my essay was flagged by an AI writing detector and she wants to meet to discuss it. The thing is, I wrote this paper entirely myself. I spent weeks on it, went to office hours, did multiple drafts. I didn't use ChatGPT for anything except maybe brainstorming some initial ideas, and even then, I didn't copy anything. I'm an international student, and I've read that detectors are biased against non-native English writers . Is that what's happening here? How do I prove I wrote my own paper? I have Google Docs history with timestamps showing my writing process over several weeks. Will that be enough? I'm terrified of being accused of cheating when I did nothing wrong. Has anyone else been through this? How did you handle the meeting with your professor?
