Free Online ChatGPT AI Detector
Introducing the Free Online ChatGPT Detector — a simple, transparent way to estimate whether text might be AI‑generated or human‑written. Paste any passage below and click Detect. You’ll get human/AI percentages, word & sentence counts, plus a quick confidence read. All analysis happens in your browser.
This fixer makes light, local edits (simpler wording, varied rhythm). Always review — detectors can be wrong and context matters.
We compute simple, transparent metrics often used in stylometry: sentence‑length variance (“burstiness”), type‑token ratio, repetitiveness of word n‑grams, stop‑word share, punctuation patterns, and character‑level entropy. A weighted blend produces an AI likelihood. Longer, more varied human writing tends to have higher burstiness and diversity; AI text often shows smoother sentence lengths and different function‑word patterns.
Limitations: All AI detectors, including this one, can be wrong. Short or heavily edited texts reduce accuracy. Treat results as a rough indicator only — not proof. When in doubt, ask for drafts, sources, or writing samples.
