How AI Detectors Analyze Text
While each detector uses proprietary methods, most rely on a blend of statistical patterns and machine learning models.
Perplexity & Burstiness
Detectors measure how predictable text is. AI often produces consistently predictable sentences with low burstiness compared to varied human writing.
Sentence Structure Patterns
AI tends to use similar sentence lengths, transition phrases, and balanced structures. Detectors flag text with unnatural uniformity or template-like flow.
Lexical Diversity
Limited vocabulary, lack of idioms, and repetitive phrasing signal AI output. Human writers naturally mix vocabulary, slang, and domain-specific terms.
Stylistic Fingerprints
Some detectors compare text against known AI outputs or use neural models trained to recognize subtle stylistic cues unique to AI models.
Responsible AI Humanization Workflow
Follow this process to combine AI efficiency with human authenticity and reduce false positives.
1
Diagnose detector signals
Paste your draft into Humaniser’s AI detector analysis to review burstiness, readability, and sentence variety scores.
2
Rewrite with Humaniser
Use the humanizer tool to expand vocabulary, insert conversational tone, and personalize examples without losing intent.
3
Layer human context
Add anecdotes, source citations, or process explanations that show original thinking and reduce AI-like uniformity.
4
Re-run detection checks
Re-test the updated draft with multiple detectors and adjust transitions or structure until scores consistently drop.
Key Detector Benchmarks to Monitor
Track these quantitative signals before submitting work. If your draft hits the safe ranges below, the chance of triggering GPTZero, Turnitin, or Originality.ai drops dramatically.
Burstiness above 0.85
Aim for noticeable variance between sentences. Short, uniform sentences are flagged quickly by GPTZero and Copyleaks.
Perplexity over 40
Higher perplexity signals original thinking. Layer explanations, examples, and qualifiers to push your average above safe thresholds.
Human edit time ≥ 5 minutes
Manual edits matter. Spending a few minutes refining tone, transitions, and citations dramatically lowers AI probability scores.
Source references & lived experience
Add citations, personal anecdotes, or original research snippets. Detectors look for contextual grounding that generic AI text lacks.
Human Editing Checklist for Authentic Tone
Apply these quick edits after running Humaniser so your voice, expertise, and nuance shine through every paragraph.
Add Personal Insights
Include your own experiences, data, and perspectives. Specific details that only you would know make text sound authentically human.
Vary Structure & Tone
Mix sentence lengths, add rhetorical questions, use contractions, and allow natural imperfections. Human writing isn't perfectly polished.
Fact-check & Edit
Verify AI-generated content, correct inaccuracies, and ensure tone matches context. Authentic editing improves quality and reduces AI signatures.

How do AI detectors identify AI-generated text?
Most detectors analyze patterns like repetitiveness, low lexical diversity, predictable sentence structures, and burstiness (variance between sentences). Some compare text against large databases or look for AI signature phrases.
Why do false positives happen?
False positives can occur when legitimate writing has formulaic structure, high correctness, or limited vocabulary—common with non-native speakers and academic or technical writing. Detectors use probabilities, not certainties.
Can I make AI-assisted writing undetectable?
Heavily humanized content often scores as human-written, but no approach guarantees 100% undetectability across all systems. Focus on creating authentic, high-quality writing rather than chasing scores.
Does Google penalize AI-generated content?
Google penalizes low-quality content, regardless of how it's produced. Helpful, people-first content—whether AI-assisted or human-only—can rank well. Humanization improves readability and engagement, which indirectly supports SEO.
