Our verdict
ZeroGPT is a free AI content detector that identifies text generated by ChatGPT, Claude, Gemini, and other AI models. Its simplicity and free access make it the most accessible AI detector. Best for quick checks. The main caveat is lower accuracy than Copyleaks and Turnitin, with notable false positive rates on human-written text.
