Receive PDF Report
Your detailed PDF report arrives by email in as little as 15 minutes. It includes a plagiarism score, color-coded highlights, and direct source links for every match found.
What the Plagiarism Checker Detects
Our plagiarism checker goes beyond simple copy-paste detection. It identifies four distinct forms of academic dishonesty and flags them all in a single report.
Direct Plagiarism
Word-for-word copies from any source without citation. Highlighted in red with source link.
Paraphrase Plagiarism
Ideas taken and reworded without attribution. Highlighted in yellow when structural matches are found.
Synonym Substitution
Replacing key words with synonyms to mask copied text. Highlighted in orange by pattern analysis.
Self-Plagiarism
Reuse of your own previously submitted or published work without disclosure. Also detected and flagged.

Plagiarism Checker — Frequently Asked Questions
A plagiarism checker analyzes your text by breaking it into segments and comparing each segment against a vast database. Our tool uses PlagAware, which searches over 70 billion sources — including academic databases, published websites, digital libraries, and previously submitted papers. Every matching passage is flagged with a color-code, a similarity percentage, and a link to the original source.
The PDF report contains: (1) an overall plagiarism percentage, (2) all detected matches color-highlighted by type — red for direct copies, yellow for paraphrases, orange for synonym substitutions, (3) clickable URLs linking directly to each original source, and (4) page numbers so you can locate every flagged passage in your document.
Yes — this is one of the key strengths of PlagAware. Unlike basic plagiarism tools that only catch exact matches, PlagAware uses semantic analysis to detect paraphrased content (where the meaning is copied but the words differ), synonym substitution (replacing words with synonyms), and structural imitation. This gives a more accurate and comprehensive result.
Pricing is based on the number of standard pages in your document. One standard page equals 1,800 characters including spaces — the international academic standard. We automatically calculate the page count from your uploaded file. A Plagiarism Scan costs $0.29 per page, with a minimum charge of $0.90.
Absolutely. Our plagiarism checker handles documents of any length — from short essays to full dissertations (up to 999 pages). For theses and dissertations, we recommend the Combo package (Plagiarism + AI Scan) to get comprehensive coverage against both traditional plagiarism and AI-generated content at the best possible price.
Yes. We offer a 100% money-back guarantee. If you do not receive your report within the expected time frame, or if there is a technical issue preventing a valid scan result, we will refund your payment in full — no questions asked. Contact us at kontakt@plagiarism-checker-online.net.
