What to watch out for
No AI detector is fully reliable, and X Detector is no exception. Results can be wrong in both directions, flagging human writing or missing AI text, so the output should be one input in a review, never the sole basis for a grade or an accusation. Using it to punish a student without other evidence could be unfair, and any consequences of a decision remain the responsibility of the person or institution making it. The free service and its accuracy claims could also change over time. Follow your school or platform rules about how detection tools may be used.
