Plagiarism Checker
Understand overlap risk in your wording with a quick originality check.
This tool reads only the text you paste. It does not search the web or compare against academic databases—it is a writing-quality and originality-style heuristic to support your own editing.
How the originality check works
What it checks
It reads only the text you paste and looks for generic, boilerplate or patched-together phrasing, the kind of writing that often gets a closer look from a teacher or editor.
How to read the result
You get an originality score, a risk level (low, medium or high), a short explanation and suggestions for rewriting the weak parts in your own words.
What it is not
It does not compare your text with the web or with paper databases, and it is not proof of originality for school. For source matching, use the tool your institution approves.
Frequently asked questions
Does this compare my text to the internet or paper databases?
No. It does not crawl the web or match against academic corpora. It analyzes the pasted text itself for generic, boilerplate or patchwork patterns that often trigger manual review.
Can I submit this result to my school as proof of originality?
No. Use it as a self-edit aid only. Institutions expect approved tools and policies, so check with your instructor.
How is this different from an AI detector?
AI detection estimates machine authorship. This check focuses on whether the writing reads overly generic or stitched together. Both are heuristics, not legal findings.
Is my text stored?
Text is processed for the request and not stored for training. See our privacy policy for details.
How long can my input be?
Between 20 and 4,000 characters per run on the web.
