Frequently asked questions
How accurate is the AI content detector?
It gives a probability estimate per sentence rather than a definitive verdict. AI detection is inherently probabilistic, so use the scores as guidance, not proof.
Is my text kept private?
Yes. Text is analyzed in the moment and not stored or used for training.
Is the AI detector free?
Yes. The LetX AI Content Detector is free with no signup required.
