AI Writing
Know whether the text is original before you publish it
Paste any draft and the Plagiarism Detector checks it against online sources, flags duplicated passages, estimates the likelihood of AI-generated text, and links you to the sources it matched.
What is the AI Plagiarism Detector?
The AI Plagiarism Detector checks text for two things that matter before anything goes live: whether passages already exist elsewhere online, and whether the writing shows the statistical fingerprint of machine-generated text. You paste the content, run the scan, and get a report instead of a guess.
Matches are shown passage by passage with links to the sources they came from, so you can see exactly what overlaps and decide whether it needs a rewrite, a quote or a citation. That makes it useful in both directions: checking work you are about to publish, and checking work submitted to you.

How it works
Using the AI Plagiarism Detector
- 01
Paste or upload the text
Drop in the draft, article, essay or product copy you want to check.
- 02
Run the scan
The detector compares the text against online sources and analyses writing patterns.
- 03
Review flagged passages
Each match shows the overlapping text and a link to the source — judged in context, not by a score.
- 04
Fix and re-check
Rewrite, quote or cite the flagged sections, then scan again to confirm the document is clean.

Freelance article check
Input
Scan a 1,800-word submitted article before paying the invoice.
Output
Originality 91%. Two flagged passages: a 38-word block matching a 2023 industry report (source linked) and a paragraph rated likely AI-generated. Everything else is clean.
Landing page rewrite
Input
Re-scan the page copy after rewriting the matched sections.
Output
Originality 99%. No source matches above threshold. AI-likelihood score low across all sections.
Key features
What the tool gives you
Source-linked matches
Every flagged passage links to the page it matches, so nothing rests on the percentage alone.
AI-content detection
A separate signal estimates whether the text reads as machine-generated, independent of duplication.
Passage-level reporting
Results are broken down per passage rather than a single number for the whole document.

Pre-publish check

Rewrite verification
After reworking AI-assisted drafts, scan to confirm the final text reads as original.
Tips that improve results
- Read the matched source before rewriting; sometimes a citation is the right fix, not new wording.
- Scan at the draft stage, not after design and layout are done.
- Treat the AI-likelihood score as a prompt to review, not a verdict.
Mistakes worth avoiding
- Ignoring small matches — a string of short duplicated phrases adds up.
- Rewriting by swapping synonyms, which rarely clears a match and usually reads worse.
- Publishing without re-scanning after edits.
AI Plagiarism Detector FAQ
What sources does it check against?
The scan compares your text against publicly indexed online sources and returns links to any pages that match.
Does it detect AI-generated text?
Yes, it includes an AI-likelihood estimate alongside duplication matching. Treat it as a review signal, since no detector is perfect in either direction.
Can I check a whole document?
Yes. Paste the text or upload the file and the scan runs across the full document, reported passage by passage.
