Confidence and next steps

Context only. Scores can help you review text, but they do not prove authorship or origin.

Use as context, not proof. AI Checker Lab estimates probability and confidence. It cannot prove authorship or origin.

How it works

From paste to a reasoned answer in three steps.

  1. Add content

    Paste text or upload an image.

  2. Review the reasons

    Check the probability, confidence, and strongest reasons.

  3. Use context

    Treat the score as decision support, never as a verdict.

What you get

Check AI probability without treating it as proof.

Paste text or upload an image, then use the probability, confidence, and key reasons as context for a human decision.

  • Probability is an estimate, not proof.
  • Confidence changes with length, clarity, and available evidence.
  • Reasons show why more context may be needed.
  • Signed-in users can save check history in their account.

FAQ

Questions, answered.

Is the score proof?

No. It is a probability estimate for cautious review.

Can I check images too?

Is AI Checker Lab free?

Yes. A free account includes 5 text or image checks and 5 social account checks every month. Pro and Creator plans add more checks, longer inputs, and saved history.

Which languages can it check?

The site and results are available in English, Korean, Japanese, German, French, Spanish, Italian, and Chinese, and the checker reads text written in those languages.
