🤖 AI Writing Detector
Advanced detection using perplexity, burstiness, punctuation, AI phrases, em-dash usage, and repetition. No data leaves your browser.
⚡ How it works: This detector uses 7 linguistic signals:
• Em dash "—" – AI loves it, humans rarely use it. (Strongest signal)
• Perplexity – randomness of character sequences (AI is more predictable).
• Burstiness – variation in sentence lengths (human writing is more varied).
• Punctuation patterns – overuse of commas and semicolons (AI characteristic).
• AI‑typical phrases – common ChatGPT/Gemini expressions.
• Repetition – AI sometimes repeats n-grams excessively.
• Transition words – "however", "therefore", "moreover" (AI overuses).
📊 Score: 0‑30% = Human | 30‑70% = Uncertain | 70‑100% = AI‑generated.
