Plagiarism Checker
Compare your draft with your sources or an earlier version. See an overlap score, the matching passages highlighted, and phrases you repeated. Runs in your browser.
This checks your draft against texts you paste: your sources, a classmate’s earlier draft, your own old report. It does not search the internet or your college’s database, so a low score is not a guarantee. Everything stays in your browser.

About this tool
What is Plagiarism Checker?
Plagiarism Checker compares your draft with texts you paste, such as the sources you used, a classmate's earlier version or your own old report. It finds phrases of five or more words that appear in both, highlights them in your draft, and gives an overlap score. It does not search the internet or a college database, so use it to clean up your own work, not as proof of originality.
Useful when you need to
- Check a draft against the articles you copied notes from before you submit
- Make sure a rewrite really changed the wording of your source
- Compare two versions of the same report to see what stayed identical
- Find phrases you repeated inside a long report
How to use
How to use Plagiarism Checker
01 02 Add the texts to compare
Paste each source into its own box and give it a name. Up to five texts.
03 Run the check
Press Check overlap. You get a score, a coloured breakdown by text and your draft with matching passages highlighted.
04 Fix what is flagged
Rewrite highlighted passages in your own words, or put them in quotation marks and cite the source. Run it again to confirm.
Tips
Get better results
- A match is not automatically plagiarism. Names, definitions and quotations overlap. Look at each highlighted passage.
- Quoted matches are shown but not counted in the score. They still need a citation.
- Changing a word here and there does not fix a close copy. Rewrite the idea from memory, then add a citation.
FAQ
Frequently asked questions
Does it check the internet?
No. It only compares with the texts you paste. Your college may use a broader system, so a low score here is not a guarantee.
Is my text uploaded?
No. The comparison runs in your browser and nothing is sent to LazyStudents.
What does the score mean?
It is the share of your draft's words that sit inside a phrase of five or more words found in a text you supplied, not counting quoted text.
Which files can I load?
Plain text files (.txt, .md). Copy text from Word or PDF and paste it.
