Most AI detectors promise perfect accuracy. AIScan doesn't. It gives you similarity percentages with honest guidelines instead. Under 33% suggests human writing. Around 50% points to rewritten or mixed content. Over 66% indicates AI generation.
Detection happens fast. You paste your text, hit Check Text, and get results in seconds. AIScan analyzes everything — single paragraphs to full essays. It looks for statistical patterns that reveal LLM fingerprints from ChatGPT, Gemini, or Claude.
Privacy gets serious attention here.
Your text hits a German server for evaluation, then gets deleted immediately. Data travels encrypted. Nothing gets stored or shared with third parties.
Say you're a college instructor reviewing a suspicious essay submission. You can drop the entire paper into AIScan and get a percentage that helps inform your decision without claiming absolute proof. AIScan acknowledges what other detectors won't: human sentences sometimes trigger false positives, and AI text can slip through undetected.
AIScan runs entirely free with no paid tiers. The developers chose honesty over marketing hype — admitting their results aren't legally binding and can't provide ironclad proof of AI use. More text improves accuracy. Perfection stays out of reach.
This approach feels refreshingly straightforward in a field full of overconfident claims. You get useful data without the false promises.
