AI Text Classifier for Web

Summary of the tool

AI Text Classifier is a free web utility from OpenAI that estimates whether a piece of writing was produced by a person or generated by AI. The interface is straightforward: paste a passage (the service requires at least 1,000 words) and submit it. In a few seconds the tool returns a simple likelihood judgment instead of a line-by-line breakdown.

How to use it

• Paste the text you want evaluated into the input area.
• Make sure the selection meets the minimum length requirement (about 1,000 words).
• Click submit and wait a few moments for the result to appear.

The app is designed to be quick and approachable so users can check content without a steep learning curve.

Output categories and what they mean

• Likely AI-generated — the classifier judges the passage as more probably produced by a machine.
• Possibly AI-generated — the result indicates a moderate chance it was generated by AI.
• Unclear — the model cannot make a confident determination either way.
• Unlikely AI-generated — the text seems more consistent with human authorship.
• Very unlikely AI-generated — the classifier strongly favors human origin.

These labels are intentionally simple to read, though they do not show which sentences or phrases drove the decision.

Strengths and shortcomings

The tool offers a clean interface and a rapid workflow, making it useful for quick checks by teachers, editors, and others. However, it is not infallible: it can produce false positives (labeling human writing as AI-produced) and it cannot claim perfect accuracy. OpenAI notes the classifier was initially trained primarily on English-language material written by professionals, and the system is expected to improve over time with continued usage and refinements.

Who might find it useful

• Professionals who need a quick content check before publication.
• Educators looking for a simple way to screen student submissions.
• General users curious about the origin of a given passage.

Additional note and recommendation

Although still evolving, the classifier is a useful starting point for assessing authorship at a glance. For critical decisions, combine its output with manual review and other verification methods.
