You've been accused of using AI: what to gather

General information, not legal advice. It cannot tell you how a particular teacher, client or organizer will decide.

1. Find the process evidence that already exists

Evidence of how a piece was made is often already stored by the tools you used. Look for:

2. Put it in time order

Make one list, oldest first. For each item write the date, what the file is, and where it came from. Keep copies of the original files; do not rename or edit them. Screenshots of version history are useful as an addition, not as a replacement for the files.

3. What not to say

4. If you have nothing yet

If, after checking the places above, you have only the final file, say so plainly rather than producing anything new. For your next piece, start keeping a record before you begin.

A record of file times cannot prove that no AI was used, and it cannot make anyone accept it. Whether it is accepted is up to whoever you show it to.
