Preguntas frecuentes
What is a GPT killer?+
A GPT killer estimates how likely a piece of text was generated by ChatGPT or another GPT model. It analyzes writing patterns and shows a 0–100 score, a proportion graph, and sentence-level highlights.
Is the GPT killer free and unlimited?+
Yes. AI Killer's GPT killer is completely free, requires no account, and has no daily limit on checks. Paste your text and check instantly.
Is any GPT killer 100% accurate?+
No. GPT killers are probabilistic and can both flag human writing and miss AI text, especially on short passages. Use the result as a signal, never as the sole basis for a decision.
