What to evaluate
Understanding How AI Detectors Actually Work
These are the signal criteria that matter — not features that look impressive in a product tour.
Pattern Matching
Originality.AI and similar tools compare structural and stylistic patterns against known AI model outputs — one reason "how does originality.ai work" doesn't have a simple yes/no answer.
Perplexity Scoring
Word-level predictability is a core signal for Originality.AI. Formal or heavily-edited human writing can score similarly to AI output on this metric alone.
Known Limitations
Originality.AI's false-positive rate, like every detector's, rises on non-native English and highly formal writing styles — a documented, category-wide limitation.
Burstiness Analysis
Sentence-length variation (burstiness) tends to be lower in AI output than human writing, though skilled editing narrows this gap considerably.
