Question 1

How does an AI content detector work?

Accepted Answer

AI content detectors analyze text for patterns common in AI-generated content, including perplexity (word choice), burstiness (sentence length variance), repetition, and known AI phrasing patterns. Lower perplexity and more uniform sentence lengths typically indicate AI-written text.

Question 2

Can AI detectors be fooled?

Accepted Answer

Yes, AI detectors can be fooled by heavily edited AI text, mixed human and AI writing, or texts with intentionally varied sentence structures. No detector is 100% accurate, and results should be considered estimates rather than definitive proof.

Question 3

Is this AI content detector free?

Accepted Answer

Yes, this AI content detector is completely free to use. It runs entirely in your browser with no signup, no API keys, and no usage limits. All analysis happens locally on your device.

Question 4

What is perplexity in AI text detection?

Accepted Answer

Perplexity measures how predictable text is. AI-generated text typically has lower perplexity because language models choose the most probable words, while human writing shows more varied and unexpected word choices.

Question 5

What is burstiness in AI detection?

Accepted Answer

Burstiness measures variance in sentence length. Human writing naturally mixes short and long sentences, creating higher burstiness. AI text tends to have more uniform sentence lengths, resulting in lower burstiness scores.
