AI Content Detector
Analyze linguistic patterns, sentence 'burstiness', and vocabulary diversity to detect AI-generated content.
Probabilistic results based on local heuristics
Expert Tips
Get the most out of this tool
Human writing is 'bursty'—it combines short, punchy sentences with long, complex ones.
AI models often choose the 'most likely' word, leading to a predictable vocabulary pattern (Low Perplexity).
Higher word counts provide more data points and lead to more accurate detection results.
Content that is 100% human-written should aim for high 'Vocabulary Diversity' and low 'Uniformity'.
Why use this tool?
In-depth Analysis & Guidance
AI detection works by quantifying the 'randomness' and 'complexity' of text. Machines are mathematically designed to be predictable, whereas humans are naturally inconsistent in their writing rhythm.
Burstiness
Measures the variance in sentence length and structure across the text.
Perplexity
Measures how 'surprising' the word choice is compared to common AI training data.
