An October 2025 article in ZDNet identified 11 content detectors, including BrandWell, Copyleaks, GPT-2 Detector, GPTZero, Grammarly, Pangram, Originality, QuillBot, Undetectable, Writer and ZeroGPT. It advised caution before relying on the results of all of these tools.

The article went on to say that chatbots such as ChatGPT, Grok, Gemini and Copilot can also be used to determine if content is original or not and they do a decent job of detection as well. See
