Who it is for

What to watch out for

Published accuracy and false-positive rates come from the vendor's own testing, and independent work repeatedly shows detectors misclassifying human writing, especially non-native English and formal prose
Fragment-level marking looks precise but rests on the same probabilistic signal
Automatic LMS screening means judging every student by default, so policies, appeals and human review are essential
Submitted text leaves your organisation, so check processing and retention terms
