AI Content Detector | Check if Text is AI-Generated

Analyze any text to estimate the probability it was written by AI (ChatGPT, GPT-4, etc.). Get detailed insights and highlighted patterns – all processed locally in your browser.

All processing happens in your browser – no data leaves your device.

How Does It Work?

Our detector analyzes several linguistic features:

  • Sentence length variation: AI often produces uniformly structured sentences.
  • Word repetition: AI may overuse certain transitional phrases.
  • AI-specific vocabulary: Words like "furthermore", "moreover", "delve" are AI favorites.
  • Perplexity: Human writing is less predictable; AI tends to be more "perfect".

We combine these metrics into a probability score. While not 100% accurate, it provides valuable insight.

Tips for Accurate Detection

  • Paste at least 200 words for reliable results.
  • Use the tool as one of several indicators, not absolute truth.
  • For best results, analyze your text without heavy editing or formatting.
  • Remember: high AI score doesn't automatically mean "bad" – AI tools are legitimate writing aids.

Does it work with all AI models?

It's trained on patterns common to GPT-3/4, ChatGPT, and similar models. Newer models may have different patterns.

Will my text be stored?

No. All processing is done in your browser. We never receive your text.
