Frequently Asked Questions
How should I read the AI Detector percentage?
Scores under ~35% read as human-written on the tool's own meter; higher scores flag AI signals, with very high scores the strongest. Treat the middle band as 'needs human review', not a verdict. A 2,000-word essay scoring 82% deserves a conversation with the author, not an automatic accusation.
Is my checked text uploaded or stored?
No — all analysis happens locally in your browser with pattern statistics, so checked text never leaves your device. Safe for student submissions and unpublished drafts; nothing is sent to any server.
What is burstiness and why does it matter?
Burstiness measures sentence-length variation: humans mix short punches with long explanations (high burstiness), while raw AI output stays uniform (low burstiness). Heavily edited AI text regains burstiness, which is why the score is one indicator among several, never a final judgment.
Can students evade AI detection?
Yes — paraphrasing, mixed human-AI drafting, and careful editing all lower scores, so a low score never proves human authorship either. Use the tool as a screening signal alongside process evidence (drafts, outlines, in-class writing), not as a sole academic-integrity verdict.
