Frequently Asked Questions
Is my text sent to a server?
No. All analysis runs entirely in your browser using JavaScript. Your text never leaves your device and is not stored anywhere.
Can this tool definitively prove AI authorship?
No. This tool reports **statistical signals** commonly associated with AI-generated text. It does not prove authorship. Human-written text can show similar patterns, and AI text can be edited to avoid detection.
What signals does the tool detect?
The tool analyzes vocabulary uniformity, sentence length variation, word frequency distribution, punctuation patterns, and other statistical indicators that differ between typical human and AI writing styles.
How accurate is the detection?
The tool provides signal-based analysis, not a definitive verdict. It works best on longer texts (500+ words) where statistical patterns are more meaningful. Short texts may not provide enough data for reliable analysis.
Is there a text length limit?
The tool accepts up to 50,000 characters per analysis. For best results, provide at least a few paragraphs of continuous text.
