Source matching for working drafts

Know what your draft overlaps with.

Paste your text, create a free account, and scan it for matching sources before you publish or send it.

0 words ยท 150 word min
The more words you check, the more reliable the result. Short text is more likely to produce a false positive or false negative.

A real detector, not a guess

Scores come from an established third-party detection service, not a homegrown scoring trick.

Sentence by sentence

You get the passages that carry the signal, not one number with no explanation.

Built for the next draft

Revise flagged passages, rescan with the same detector, and compare what changed.

A trail, not a claim

Every saved version records the result and changes without pretending a score proves authorship.

A clear read, with a useful next step.

Results stay connected to a real working draft. Review the supporting detail, then carry the same text into your next check or revision.

Sources, not a mystery score

See the pages that overlap with your draft and how much of the text is implicated.

Highlights in the original text

Matched passages are marked inline so you can review the exact wording without comparing documents by hand.

One workspace for every check

Run AI detection and fact checking on the same text when you need a fuller content-integrity read.

Checks well over a hundred languages

Source matching is not limited to English drafts, so translated or multilingual content gets the same scan.

Questions

Can I check plagiarism for free?+

A free account includes monthly credits for plagiarism checks. We ask you to sign up before running a scan because source matching is a full report, not a preview.

Will this scan my text before I sign up?+

No. The text box only prepares your draft for the next step. We do not run a plagiarism analysis until you have created or signed in to an account.

What does a plagiarism result show?+

Your report includes an overlap score, matching sources, and inline highlights that show where the source overlap appears in your text.

Check the draft. Then keep working.

Review AI signals, source overlap, and factual claims, then carry the same draft into your revision workflow.
