What to evaluate

How AI Detection Works — and How to Stay Ahead

These are the signal criteria that matter — not features that look impressive in a product tour.

📊

Perplexity Analysis

AI detectors measure how predictable each word choice is. AI text scores abnormally low. Essayfilter raises perplexity to human range.

📏

Burstiness Detection

AI produces uniform sentence lengths. Detectors flag this pattern. Essayfilter introduces natural variation that matches human writing.

🧬

Semantic Fingerprinting

Detectors map semantic patterns against known AI model outputs. Essayfilter disrupts this mapping completely.

🔬

Token Probability Scoring

Detectors analyze token probability distributions. Essayfilter redistributes these into human norms.
