Common questions
Frequently asked questions
Our detection engine analyzes writing patterns, sentence structure, vocabulary choices, and stylistic markers across multiple AI models. We look for statistical anomalies that distinguish machine-generated text from human writing, providing sentence-level evidence for every finding.
Voice Match compares submitted work against known writing samples to verify authorship. By analyzing vocabulary, syntax, tone, and stylistic fingerprints, we can determine whether a document matches an author's established writing pattern.
Yes. Every analysis generates a certification-ready PDF report with unique report IDs, timestamps, confidence scores, and detailed evidence. These reports are designed for academic records, appeals, and institutional documentation.
Our multi-model approach achieves over 99% accuracy in controlled testing. We prioritize transparency by showing confidence levels and evidence for every finding, helping you make informed decisions rather than relying on a single score.
When AI signals are detected, the Humanizer suggests specific, targeted edits to reduce them while preserving your original meaning and voice. Unlike full rewrites, it makes surgical changes only where needed, with before/after comparisons.
Absolutely. Documents are processed securely and never stored permanently. We do not train on your submissions, share content with third parties, or retain data beyond the analysis session. Your academic work remains yours.
