    How DeepDetector Detection Works

    Discover the core linguistic metrics and workflow features that make our originality checks highly reliable.

    1. Perplexity (Word Predictability)

    Predictability

    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.

    Low Perplexity (Predictable)
    The climate change is a global problem.
    High Perplexity (Natural)
    Untangling climatic shifts reveals a messy tapestry of vulnerability.

    2. Burstiness (Sentence Variation)

    Sentence Variation

    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.

    How to Verify Text Originality in 3 Steps

    1

    Input Your Content

    Paste your draft directly into the text editor or drag-and-drop a PDF, Word (DOCX), or plain text file.

    2

    Choose Scan Mode

    Select Quick Scan for instant checks, or Deep Scan to run your text through our full multi-model classifier ensemble.

    3

    Review Highlighted Evidence

    Examine sentence-level highlight patterns. Darker highlights indicate higher probability of AI-generated content.

    Free quick-scan AI detection for accountable writing review

    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.

    Start with a free quick scan

    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.

    Evidence-first AI writing review

    DeepDetector frames detection as a review workflow: inspect risk signals, understand where they appear, and decide what follow-up is appropriate.

    Pair scores with judgment

    A score is only one signal. Combine detector output with source checks, draft history, citation review, and clear disclosure expectations.

    FAQ

    Can I use the AI detector for a free quick scan?

    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.

    What does the AI detector check?

    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.

    How should I use detector results responsibly?

    Review highlighted passages, check false-positive risk, compare against writing history, and document follow-up decisions before taking academic, editorial, or workplace action.
