Dear Turnitin,

I was surprised to see that a student of mine´s final extended essay is showing a high percentage of AI (48%). Assuming that this is a reliably measured as I can see that your methodology is clearly described, how can I best determine what exactly led to this high level:

1) Does turnitin help me see what tools were used as AI?

2) Is Turnitin checking this work against an earlier version of the work by the same student?
