AI Detector Methodology

This page explains what the Ink Humanizer AI detector measures, what its score means, and — just as importantly — what it cannot tell you. We publish this so you can interpret results responsibly.

What the AI-likeness score means

The detector analyzes writing-pattern signals: repetition, sentence-length rhythm, generic or stock phrasing, and how specific the text is. It combines these signals into an AI-likeness score from 0 to 100. A higher score means the text shares more statistical patterns with typical AI-generated writing.

The score is an estimate, not proof that a text was written by AI. No detector — ours included — can determine authorship with certainty. Treat the score as a revision aid that shows where writing reads as generic, not as evidence about who wrote it.

Known limitations

• False positives: clean, evenly paced, carefully neutral human writing — the exact style school teaches — can score high.
• Non-native English writers: published research has found AI detectors flag text by non-native English speakers at a higher rate. Their results deserve extra caution.
• Short samples: the fewer words, the noisier the estimate. That is why we enforce a minimum length instead of scoring everything.
• Edited AI text and mixed authorship: heavily edited AI text and lightly edited human text can be indistinguishable to any statistical method.

Minimum text length

We require at least 40 words before showing a score, and results become steadier from roughly 150 words. Below the minimum, the tool asks for a longer sample rather than showing a number we do not trust.

Supported languages

The detector is optimized for English only. Text in other languages may return a score, but we do not consider those results reliable and you should not use them for any decision.

How to use results responsibly

• Use the sentence-level highlights to find generic phrasing and revise it with your own evidence and voice.
• Do not use the score alone to accuse anyone of misconduct — it is not designed for that, and no detector score is.
• Keep drafts and revision history; a visible writing process is stronger evidence than any score.
