Check an Article for Plagiarism

The plagiarism check is free and reports an Originality score with the matching sources it found on the open web. Rewriting the overlapping phrasing costs 100 credits, charged when the rewrite is generated.

Last updated 1 day ago

The check looks for wording in your draft that overlaps with pages already on the web. The product describes it as: "Checks distinctive passages for open-web wording overlap and rewrites high-overlap phrasing."

As with Humanize, the check is free and the rewrite costs credits.

The Check is Free

Select Plagiarism in the right-hand panel. You get:

  • An Originality score out of 100.
  • Matching sources, listed by website.
  • Excerpts shown as In your article and On example.com, so you can see the overlap directly.
  • Highlighted phrases in your draft, with the note "Yellow marks matching phrases (not single common words)."

The check is included, with a monthly fair-use allowance that scales with your plan and is set above the number of articles your plan can produce. You can check everything you write.

If the web scan cannot run you will see "Web scan unavailable. Originality is an offline estimate only." Treat that result as inconclusive rather than as a pass.

The Rewrite Costs 100 Credits

As of 2026-08-30. Charged when the rewrite is generated, not when you apply it. Keeping the original does not refund it.

Steps

  1. Open the article in the writing workspace.
  2. Select Plagiarism.
  3. Read the Originality score and the Matching sources.
  4. Look at the excerpts to judge whether the overlap actually matters.
  5. If it does, select Rewrite to generate a revision.
  6. Compare Before and After in the Review rewrite dialog.
  7. Select Apply rewrite, or Keep original.

The review dialog explains the cost: "Compare before and after. 'Apply rewrite' uses one Plagiarism run; 'Keep original' costs nothing."

Apply requires the originality score to improve by at least one point.

Reading the Results Properly

This is where judgement matters, and where the score alone will mislead you.

Some overlap is unavoidable and harmless:

  • Standard terminology. Technical terms, product names, legal phrases, and industry vocabulary have one correct form.
  • Quoted material. Deliberate quotation with attribution is not plagiarism.
  • Statistics and definitions. There is a limited number of ways to state a figure.
  • Your own content. If a match points at your own website, that is your writing.

Overlap worth acting on looks different: several consecutive sentences matching one source, a distinctive turn of phrase that is clearly someone else's, or a passage matching a competitor closely enough that a reader would notice.

Open the matching source and look. A score of 82 with matches on standard terminology needs nothing. A score of 91 with one four-sentence match against a competitor's guide is the one to fix.

What This Check is and is Not

It checks open-web wording overlap. It compares distinctive passages against publicly reachable pages.

It is not an academic plagiarism service. It does not search subscription journal databases, student paper repositories, or paywalled archives. If you need academic-grade clearance, use a service built for it.

It is not a copyright or legal opinion. It reports textual similarity. Whether something infringes is a legal question this tool does not answer.

It is not a guarantee. A high Originality score means no significant overlap was found on the pages it could reach, which is not the same as no overlap existing.

Notes

The rewrite changes phrasing to reduce overlap. It cannot fix a substantive problem, so if a passage is copied because the underlying research was thin, rewrite the section properly.

Running the rewrite again is a new charge at the same price.

There is a safety limit on how many times one article can be rewritten this way.

Generated articles do not usually have significant plagiarism, because they are written from research rather than assembled from sources. The check is most useful on articles you imported, drafts a human contributed to, or pieces covering a topic where one source dominates the results.

The Content Score pauses updating while the check or rewrite runs.

Making an article sound more human covers Humanize, which follows the same free-check, paid-rewrite pattern. What each action costs lists both prices alongside everything else.
