How to use an AI-writing pattern check responsibly

This checker estimates whether a passage contains patterns commonly associated with generated text. It is designed for review and discussion, not for proving who wrote a document or identifying a specific model.

What this tool can help with

  • Reviews sentence variation, predictability, and other writing patterns.
  • Provides an estimate that can help focus a manual review.
  • Keeps the original passage visible so you can compare the result with its context.

Important limitations

  • A high score is not proof that AI wrote the text.
  • Human writing can produce false positives, especially when it is formal or heavily edited.
  • The checker cannot reliably identify GPT, Claude, Gemini, or another specific model.

A reliable three-step workflow

  1. 1. Add a useful sample. Use enough context for the result to be meaningful, but do not submit private or confidential information.
  2. 2. Compare the result. Keep the original visible and review changes, scores, or suggestions one at a time.
  3. 3. Verify before use. Check facts, names, numbers, meaning, sources, and any rules that apply to your work.

Frequently asked questions

Can this prove that a student used AI?

No. Use drafts, version history, sources, and a conversation with the writer when authorship matters.

What should I do with a high score?

Review the highlighted patterns and supporting evidence. Do not make a high-stakes decision from the score alone.
