GPT Zero is an online tool for detecting text generated by AI models such as ChatGPT, GPT-4, GPT-3, GPT-2, and LLaMA. It helps distinguish machine-written content from human writing and supports transparency in content workflows.
One-step AI content detection
Paste text into the input field, run a scan, and get an estimate of how likely the text is AI-generated. The interface is designed for quick checks of common formats:
- Articles and blog posts
- Essays and academic assignments
- Social media posts and other short-form text
Content quality control for teams
GPT Zero can be useful for people who need to verify the origin of text and maintain consistent standards:
- Editors and publishers
- Teachers and academic staff
- Marketers and content writers
Plagiarism and authenticity screening
In addition to a “human vs AI” assessment, GPT Zero can serve as an extra signal during originality checks. It doesn’t replace traditional plagiarism tools, but can complement them by flagging text that may be machine-generated and worth closer review.
