What does an AI essay detector do?

An AI essay detector analyses essays to determine if written by a human student or generated by AI — checking for consistent structure, low burstiness, and formal AI hedging language patterns.

Can students bypass AI essay detection?

Detectors can be partially bypassed by paraphrasing tools, but most check multiple signals simultaneously making simple paraphrasing insufficient to fully avoid detection.

Is the AI essay detector free?

Yes — completely free, no account required.

Can teachers use this to catch students?+

Yes — but treat it as a starting point for a conversation, not as proof. False positives are possible, especially for ESL students whose writing can superficially resemble AI patterns. Always combine with other evidence.

What score means AI-written?+

70%+ is a strong AI signal worth investigating. 40–69% is uncertain — could be AI-assisted or edited AI content. Under 40% suggests primarily human writing.

Does it detect ChatGPT specifically?+

It detects patterns common to all major LLMs (ChatGPT, Claude, Gemini, Llama). The patterns — uniform sentence structure, hedging language, low burstiness — are shared across all models.
