⚠️ Important: AI detection is not 100% accurate. This tool analyses writing patterns such as perplexity, burstiness, and sentence structure — but no detector can guarantee certainty. Use results as a guide, not a definitive verdict. Human-edited AI content and some formal writing styles may score higher for AI probability.

🔍 AI Writing Signals

📊

Low perplexity — AI text is predictable. Each word follows the most probable pattern.

📏

Low burstiness — Human writers mix short and long sentences. AI uses uniform sentence lengths.

🔄

Repetitive transitions — Phrases like "Furthermore," "It is important to note," and "In conclusion" are common in AI.

🎯

Perfect structure — AI content is always perfectly organised. Human writing has natural imperfections.

😐

Neutral tone — AI rarely uses strong opinions, personal anecdotes, or emotional language.

💡 For SEO Writers

✍️

Google doesn't penalise AI content directly — it penalises unhelpful, low-quality content.

🔄

Edit AI content heavily — add personal examples, opinions, and specific data points.

📊

Add original research, quotes, and first-hand experience to make AI content rank better.

🎯

Use AI as a first draft, not a final product — human editing significantly improves quality.
