Plagiarism Checker for Students
Check your essay, paper, assignment, thesis, or other coursework for matching text and sources before you submit. Review each match in context and decide what needs attention before you turn in your work.

Review every match before you submit
A similarity score is only a starting point. Open a highlighted passage to see the matching source and its context, then review citations, references, and other report signals before deciding whether anything needs to change.
Climate change and the economics of food
The economic implications of climate change extend beyond environmental damage and touch every part of modern agricultural systems.
Recent studies have shown that rising global temperatures correlate with decreased yields in rain-fed regions, and that the effect compounds where irrigation is unavailable.
However, smallholder farmers in West Africa have adapted through diversified cropping patterns and drought-resistant millet varieties.
What the models leave out
Most projections treat adaptation as a fixed parameter rather than a decision made season by season under uncertainty.
Field data from recent seasons supports this reading across tropical zones, though the sample remains too small to generalise from with confidence.
Further work should separate the price effect from the yield effect before either is used to guide policy.

Student principle
Similarity is not a plagiarism grade.
A matching passage may be a quotation, a reference, common phrasing, a close paraphrase, or text that needs closer review. Look at the source and context instead of treating one percentage as a pass-or-fail result.
PlagiarismSearch surfaces matching text and sources for review. It does not decide whether a passage is plagiarism.
What to do when you find a match
-
1
Step 1
Open the matched passage
Find the highlighted text in your report and open the source connected to that match.
-
2
Step 2
Review the source and context
Check whether the match comes from a quotation, reference, common phrasing, a close paraphrase, or another passage that needs closer attention.
-
3
Step 3
Revise where necessary
If the wording or attribution needs work, revise the passage appropriately — for example, correct the citation, use quotation marks where required, or rewrite the idea in your own words.
-
Step 4
Review the updated draft
If you make changes, you can check the revised paper again and review the updated matches before submission.
Check for plagiarism
A match may be
- A quotation
- A reference
- Common phrasing
- A close paraphrase
- A passage that needs closer attention
Revise appropriately
- Correct the citation
- Use quotation marks where required
- Rewrite the idea in your own words
Control what your paper is checked against
Choose the source collections and exclusions that fit your paper before you interpret the result. Search the web and academic databases, and exclude references or in-text citations when appropriate.
- Web Search available web sources for matching or similar text.
- Academic databases Include academic database search when you want the paper compared with indexed academic material.
- Exclude references Exclude the reference section when that fits the way you need to review the paper.
- Exclude in-text citations Exclude in-text citations when appropriate for the check.
When academic database search is enabled, PlagiarismSearch can search over 500 million indexed academic texts.
Depending on your account, settings, and access, personal or organization storage may also be available as comparison sources.
Changing the source collections or exclusions changes what the report can show, so review your settings before comparing results between checks.

If you choose Add to storage, that is a separate action you control.
Running a plagiarism check does not automatically add your paper to storage.
Plagiarism and AI writing are different checks
Plagiarism checking finds text that matches available sources and shows where those matches come from.
AI writing analysis provides a separate indicator for the text you choose to analyze. It does not replace source matching and does not prove authorship.
AI-generated text is not automatically plagiarism, and a low similarity result does not prove that a text was written by a human.

Plagiarism Checker for Students FAQ
Yes. You can paste text or upload a supported document and run a plagiarism check before submission. The report shows matching or similar passages and their sources so you can review the result in context.
No. Similarity means that some text matches or closely resembles text found in the sources included in your check. A match may come from a quotation, reference, common phrasing, a close paraphrase, or material that needs closer review.
There is no universal similarity percentage that proves a paper is plagiarism-free or automatically means that plagiarism occurred. Review the individual matches, their sources, and citation context, and follow any requirements set by your course or institution.
Yes. PlagiarismSearch includes settings to exclude references and in-text citations when appropriate. Because exclusions affect what is checked and reported, review your settings before interpreting the result.
Depending on your settings and access, a plagiarism check can include web sources, academic databases, personal storage, or organization storage. When academic database search is enabled, PlagiarismSearch can search over 500 million indexed academic texts.
The uploaded file is not retained as a stored source document after processing. A generated report may remain available in your account for convenience, and you can permanently delete it. Adding content to storage is a separate action you control.
Yes. AI writing analysis can be added as a separate check when the capability and AI-word balance are available. Plagiarism checking and AI detection answer different questions: an AI result does not by itself mean plagiarism or prove authorship.
You can check up to 150 words for plagiarism without registering. Registered users receive 300 plagiarism words per day.
The checker accepts common document formats such as DOC/DOCX, PDF, TXT, PPT/PPTX, and XLS/XLSX, along with other supported formats. The current uploader shows the formats available at the time of your check.
