Look beneath a webpage.

Review the writing on a published article or webpage. Enter one public URL, check the extracted text, then choose whether to send it to GPTZero. Page metadata remains supporting context.

What this tool can tell you

Transient page evidence: this reviews one retrieved page, not an entire website and not source-code authorship.

How to use these tools and read your results

Check the writing on a public page.

Retrieve one public page, review its extracted writing, then choose whether to send it to GPTZero. This checks the selected writing, not an entire website, its images, or the authorship of its code. Pages that require JavaScript or a login may not work.

Retrieval sends this public URL to our page service. It does not send the extracted writing to GPTZero.

Only the text you approve below is sent to the detector. Extraction stays in this tab until cleared. Text over the scan limit must be edited by you; it is never silently shortened.

Inspect page metadata and structure

Review evidence from a public webpage

CouldItBe retrieves one public page once, measures its available HTML and visible text in memory, then discards the page body.

  2. 2Choose the page type
  3. 3Review the evidence

Use a public page such as example.com/article. Do not enter login pages, private links, account credentials, or restricted material.

This choice changes which text-pattern context is used. It does not change the network safety checks or produce an authorship verdict.
