AI Content Detector by Leap AI FAQ
Is Leap's AI detector free?+
Yes, detection is free forever with no signup, no word limit, and no usage quota.
How does the detector work?+
It scores each sentence using perplexity and burstiness signals and a model-specific classifier to highlight AI-like patterns.
