How the AI Detector Works

Step 01

Paste your text

Drop in up to 500 words of any content — essays, blog posts, marketing copy, legal drafts. No signup required.

Step 02

Get your AI score

Our engine analyzes perplexity, burstiness, and vocabulary fingerprints — the same signals Turnitin and GPTZero use.

Step 03

Fix what's flagged

See exactly which words and patterns triggered the detection. One click to rewrite them in your voice with our editor.

What We Analyze

AI detectors don't read your text — they measure statistical patterns. Here's what we check.

Perplexity Score

How predictable are your word choices? AI text uses statistically "safe" words. Human writing surprises more.

Burstiness Pattern

Humans write in irregular rhythms — short punchy sentences, then long complex ones. AI generates uniform length.

Vocabulary Fingerprints

Words like "delve", "landscape", "it's worth noting" are disproportionately common in AI output. We flag every one.

Structural Patterns

AI loves parallel structure, hedged opinions, and neat three-point lists. We detect these mechanical patterns.

Frequently Asked Questions

How does the AI content detector work?+
Our detector analyzes three key signals: perplexity (how predictable your word choices are), burstiness (sentence length variation), and vocabulary fingerprints (overused AI phrases). AI text scores low on perplexity and burstiness because it generates statistically average patterns.
Is the AI detector free?+
Yes. The AI content detection scan is completely free with no signup required. You can analyze up to 500 words per scan. If you want to fix flagged content, our editor offers AI humanization tools.
Can AI detectors give false positives?+
Yes. Non-native English speakers, technical writing, and formulaic academic prose can trigger false positives. Our detector shows you exactly which patterns were flagged so you can judge whether the detection is accurate.
How is this different from Turnitin or GPTZero?+
Unlike Turnitin or GPTZero, BY Wordy doesn't just flag your content — it shows you exactly why it sounds AI-generated and gives you tools to fix it. We analyze specific vocabulary, rhythm, and structural patterns rather than giving a single opaque score.
