Help Guide: How to Use the Plagiarism Checker
This guide walks you through every step of the process, from uploading your document to understanding your results. If you have a question that is not answered here, contact us at info@plagiarism-checker-online.net.
Step-by-Step Upload Guide
1 Choose your scan type
Visit the order page and select one of three options: Plagiarism Scan (looks for matching text in public sources), AI Scan (highlights AI-typical phrasing), or the Combo Package (both scans at a discount).
2 Upload your document
Click the upload area or drag and drop your file. The system will automatically extract the text and calculate the number of standard pages. You will see the page count and price before paying.
3 Enter your email address
Your report will be sent to this address. Double-check for typos. No account registration is required, just a valid email.
4 Apply a discount code (optional)
If you have a discount code, enter it in the promo code field before proceeding to payment. The price will update automatically.
5 Complete payment
Pay securely via Stripe using a credit or debit card. Payment is processed over an encrypted connection. We do not store your card details.
6 Receive your report by email
Your report is typically delivered in about 15 minutes. Check your spam folder if you do not see it. The report includes highlighted matches, source citations, and a similarity percentage.
Supported File Formats
Must contain selectable text. Scanned PDFs (image-only) cannot be processed. Use the "Save as PDF" function from Word or Google Docs.
DOCX / DOC
DOCX and DOC uploads are accepted. DOCX is preferred. Check the extracted character count before paying, especially if your file has footnotes or complex formatting.
TXT
Plain text TXT files are supported. Use UTF-8 encoding for best results. Export LibreOffice ODT documents as DOCX or text-based PDF before uploading. The maximum upload size is 50 MB for all accepted formats.
How to Calculate Standard Pages
Pricing is based on standard pages, not DIN A4 pages. One standard page equals 1,800 characters including spaces. This method is format-independent; it doesn't matter whether your document uses 12pt font, 1.5 line spacing, or wide margins.
To find your character count manually:
- Microsoft Word: Go to Review → Word Count. Look for "Characters (with spaces)".
- Google Docs: Go to Tools → Word Count (or press Ctrl+Shift+C). The dialog shows character count with spaces.
- LibreOffice Writer: Go to Tools → Word Count for character count with spaces.
Divide the character count by 1,800 to get your standard page count. Or use our Word Count Calculator to get an instant estimate with pricing.
How to Read Your Plagiarism Report
Your plagiarism report contains several key elements:
Overall Similarity Percentage
The headline figure showing what proportion of your document matched sources in our database. There is no universal acceptable similarity score. Review the individual matches and follow your assignment's rules; a low score can still contain uncited copying.
Highlighted Matches
Passages flagged as matching are highlighted in color within your document view. Each highlight links to the source it matched. In the plagiarism view, colors distinguish matched sources; they do not rate plagiarism risk.
Source List
Every matched source is listed with a URL or citation and the percentage of your document that matched it. Review each source: if you cited it correctly, the match is expected. If you did not, add the citation. For a step-by-step triage, see how to read a plagiarism report.
How to Read Your AI Detection Report
The AI detection report uses PlagAware's AI typicality measure to show how strongly the phrasing resembles patterns associated with generative AI. It does not establish which tool, if any, was used.
AI Typicality
AI typicality runs from 0% to 100%, with 50% as the neutral midpoint. Higher values indicate more AI-typical phrasing and lower values less. It is not a probability of AI authorship or a confidence score. See PlagAware's explanation.
Sentence-Level Breakdown
Each sentence or paragraph is scored individually. This helps you review specific passages. Do not rewrite genuine work solely to lower a detector score; preserve your drafts and check your institution's policy.
Important Note on AI Detection
No AI detector is 100% accurate. False positives (human text flagged as AI) can occur, particularly with highly structured or technical writing styles. Our report is a risk indicator, not a definitive verdict.
Discount Codes
If you have a discount code, enter it on the order page before completing your payment. Codes are case-insensitive. Each code may have usage limits or an expiry date; if a code does not work, it may have already expired. Contact us at info@plagiarism-checker-online.net if you have trouble with a valid code.
