Choosing and using AI Detection Tools responsibly
Who this is for
Educators, publishers, employers and organisations assessing whether text or media may have been produced or altered using AI.
What to consider
Detection results are estimates rather than proof. Accuracy can vary by language, writing style, document length, model and the methodology used by the provider.
Responsible-use considerations
A detection score should never be the sole basis for accusing, penalising or making an adverse decision about someone. Human review and a fair opportunity to respond are essential.
