About AI Content Detector

AI Content Detector is a free online tool designed to help you identify whether a piece of text was written by a human or generated by artificial intelligence.

As AI writing tools become more prevalent, the need for reliable detection grows. Our tool analyzes multiple linguistic patterns including perplexity, burstiness, vocabulary richness, and sentence variation to provide a probability score.

Multi-Language Support

Our detector works with text in many languages including English, Vietnamese, Chinese, Japanese, Korean, Spanish, French, German, Italian, Portuguese, Russian, Thai, Arabic, and Hindi. AI patterns are detected in each language's native phrases.

Our Approach

We believe in providing a straightforward, accessible tool that works directly in your browser. No sign-ups, no data collection, no limits on usage. All text processing happens locally on your device.

How It Works

• Pattern Detection — Identifies common AI writing phrases and transitions
• Perplexity Analysis — Measures how predictable the word choices are
• Burstiness Check — Evaluates variation in sentence complexity
• Vocabulary Analysis — Assesses the diversity of words used
• Uniformity Score — Detects unnaturally consistent sentence structures

Accuracy Disclaimer

No AI detection tool is perfect. Our analysis provides estimates based on statistical patterns in text. Results should be used as one factor among many when evaluating content authenticity. We recommend using longer text samples for more reliable results.
