Question 1

How accurate is AI content detection?

Accepted Answer

No detector is 100% accurate. This tool provides a calibrated probability, confidence score, and breakdown of signals (perplexity, burstiness, cliche phrases, repetitive structure). Use it as one input, not a final verdict.

Question 2

Perplexity measures how predictable the text is, low perplexity (predictable) correlates with AI output. Burstiness measures variation in sentence length, human writing tends to be bursty, AI more uniform.

Question 3

What is the text length limit?

Accepted Answer

Minimum 100 characters, maximum 8000. Longer input is truncated to 8000 characters before analysis.
