Frequently asked questions
How does the AI detector work?
It looks at patterns that are typical of AI writing, such as predictable word choice and very uniform sentence length, and gives a probability score.
Is the AI detector 100% accurate?
No AI detector is perfect. Treat the score as a signal, not proof, especially for short or heavily edited text.
Which AI models can it detect?
It is designed for text from popular models such as ChatGPT, GPT-4, Gemini, Claude and Llama.
