Is the AI detector free?

Yes — 100% free, no signup, no usage limits.

Does it save my data?

No. Inputs are processed in your browser and never uploaded to a server.

Can I use it on mobile?

Yes. The interface is fully responsive and works on iOS and Android.

No — no AI detector is. Treat the score as a signal, not proof. Even commercial detectors (GPTZero, Turnitin) report 1-15% false positives.

AI Content Detector — Free ChatGPT Text Checker

Paste a passage and get an AI-likelihood score. Analyzes burstiness (sentence-length variation), AI-style phrases, and lexical diversity — three of the strongest signals for ChatGPT-generated text. Runs entirely in your browser.

Analysis appears here. Paste at least 30 words.

How to use

Step 1: Paste the text you want to analyze (50+ words works best)
Step 2: Click Analyze
Step 3: Read the AI-likelihood score and signal breakdown

The signals this detector uses

Burstiness — humans write in bursts: short sentences mixed with long ones. LLMs tend toward uniform sentence length. Lower variation → more AI-like.

AI phrase library — phrases like "in conclusion", "delve into", "navigate the", "tapestry", "in today's" appear far more often in ChatGPT output than in pre-2022 human writing.

Lexical diversity — type-token ratio (unique words ÷ total words). Very low diversity is a soft AI signal.

Honest disclaimer: No detector is 100% accurate. Use this as a directional signal — never as definitive proof for an academic or professional accusation.
