What is GPTZero?

GPTZero analyzes text for patterns associated with AI-generated writing. It is designed to support a closer review of a document, rather than to establish who wrote it. Writers can explore their own drafts; editors and educators can use the results as a starting point for a conversation.

Free and paid plans

The official support page lists a free allowance of 10,000 words per month and a limit of 10,000 characters per scan. Essential adds grammar and vocabulary tools; Premium adds advanced analysis, plagiarism checking and writing feedback. Professional includes higher limits and organizational features.

Plan availability, local currency and billing periods can change. Check the live plans inside GPTZero before buying. No exclusive discount is claimed on this page.

A useful review workflow

  1. Choose a document you have permission to upload.
  2. Read the overall result, then inspect the passages it highlights.
  3. Compare those signals with drafts, sources and the writing context.
  4. Discuss uncertainties with the author instead of treating a score as a verdict.

Questions before you try it
