Short answer:

Use Toolyfi AI Text Detector — paste any text and instantly see the probability it was written by AI like ChatGPT, Claude or Gemini. Free, no login needed.

What is an AI Text Detector?

An AI text detector analyzes written content and determines the probability it was generated by artificial intelligence like ChatGPT, Claude, or Gemini — rather than written by a human.

As AI writing tools become more common, detecting AI-generated content has become critical for teachers, editors, HR managers, and content managers.

💡 KEY TAKEAWAY

AI detectors work by analyzing perplexity (predictability) and burstiness (sentence variation). AI text is very uniform — human text is more varied and natural.
