How to use Plagiarism Checker
A plagiarism checker compares your writing to publicly indexed content so you can spot overlap before you publish, submit coursework, or send client work. Paste plain text or upload a PDF, run the check, and review matched snippets with similarity scores. Use the results to rewrite weak sections, add citations, or confirm originality — then pair with the Word Counter for length limits.
Step 1: Add your writing
Paste plain text or upload a readable PDF. Prefer the final draft you plan to submit or publish.
Step 2: Run the similarity check
Start the scan and wait for matched snippets and an overall similarity signal against public web sources.
Step 3: Rewrite matched passages
Open each highlight, cite sources where needed, or rephrase in your own words—then re-check critical sections.

Why use Plagiarism Checker?
Similarity checks catch accidental overlap before teachers, editors, or clients do. Treat scores as a review aid, not a legal originality certificate, and always read the matched snippets yourself.

Practical tips
- Do not upload confidential legal, medical, or proprietary files unless policy allows third-party processing.
- Short common phrases may match the web even when writing is original—judge context, not only the percentage.
- Use the word counter afterward if you must stay under a hard limit after rewriting.
