Discover the core linguistic metrics and workflow features that make our originality checks highly reliable.
Perplexity measures how predictable a word is within a sentence context. AI generators write by picking the mathematically most likely next word, resulting in extremely low perplexity. Human writers express ideas with higher variation, resulting in natural spikes in word perplexity.
Burstiness measures the variation in sentence structure and length throughout a document. AI text tends to have uniform sentence lengths and standard rhythm, resulting in low burstiness. Human writers naturally mix short punchy sentences with longer complex clauses, creating high burstiness.

Select Quick Scan for instant checks, or Deep Scan to run your text through our full multi-model classifier ensemble.
Examine sentence-level highlight patterns. Darker highlights indicate higher probability of AI-generated content.

The AI detector helps educators, publishers, teams, and writers paste text or upload documents for quick-scan originality-risk review with evidence and responsible follow-up.
DeepDetector gives reviewers a free quick-scan entry point for essays, articles, reports, and policy drafts. Paste text or import a supported document to see the first set of AI-writing risk signals.
DeepDetector frames detection as a review workflow: inspect risk signals, understand where they appear, and decide what follow-up is appropriate.
A score is only one signal. Combine detector output with source checks, draft history, citation review, and clear disclosure expectations.
Yes. DeepDetector offers a free quick-scan entry point for checking AI-writing risk, with deeper validation and longer document workflows available for higher-volume review.
The AI detector reviews writing for AI-generation signals, sentence-level risk, document context, and patterns that may need human review rather than relying on a single score.
Review highlighted passages, check false-positive risk, compare against writing history, and document follow-up decisions before taking academic, editorial, or workplace action.
