Supported AI Detection Engines

GPTZero Profile

Evaluates text based on perplexity (predictability) and burstiness (structural variability). It tags paragraphs with uniform layouts as highly likely AI.

Turnitin AI Profile

Typically used by universities, it builds complex pattern maps matching semantic structures common to generative engines.

Copyleaks Scanner

An enterprise-level scanner that checks for exact paragraph repetitions, syntactic predictability, and sentence recycling habits.

Sapling Scans

Uses sequence-to-sequence probabilities to detect if sentence tokens match the predicted pathways of common text-generation models.

How to interpret your AI Score

AI scores are expressed as percentages representing the **likelihood** that the scanned text was generated by an AI assistant.

  • 70% - 99% AI (High Risk): Scanners have high confidence that the content was fully generated by an AI. Rewriting or humanization is highly recommended.
  • 30% - 70% AI (Moderate Risk): Indicates mixed writing styles or heavy AI editing. AI detectors might flag sections containing uniform structures.
  • 0% - 30% AI (Low Risk): The text displays natural variety, vocabulary changes, and human rhythms. Safely bypasses standard filters.
