Free AI Detector
Paste any text below and get an AI-likelihood score in seconds — with the exact sentences that triggered it highlighted inline. Works in English and Arabic on the same engine.
How the score works
Sahihly analyzes the statistical fingerprint of your text: how uniform the sentence lengths are, how repetitive the vocabulary is, and how many machine-typical phrases appear. Human writing is naturally uneven — it mixes short punches with long, winding thoughts. Machine writing tends to be smooth and regular. The score expresses how strongly your text leans machine-smooth, from 0 (reads human) to 100 (reads AI).
Sentence-level highlights
A single number can't tell you what to fix. That's why every analysis highlights the individual sentences carrying the strongest AI patterns, so you can see exactly where the robotic rhythm lives — and revise those lines, not the whole draft.
Built for Arabic, not translated to it
Most detectors are trained and validated on English only; run Arabic through them and you get noise. Sahihly reasons about Arabic directly — morphology, register, and natural phrasing — which is why Arabic results here are meaningful rather than decorative.
Read scores responsibly
No detector on the market is 100% accurate, including this one. Treat every score as guidance for improving style — never as proof of authorship, and never as sole evidence in an academic or professional dispute.

It provides a well-calibrated estimate based on stylistic signals, and shows its reasoning through sentence highlights. Like every detector, it can be wrong — treat results as guidance, not proof.
