Plagiarism Detector — Embed for Blogger

Plagiarism Detector

A privacy-first plagiarism helper. Paste the text to check, then either compare it against texts you provide (paste or upload files) or connect to an external plagiarism API (requires API key and server-side proxy). Client-side checks only compare to provided sources; they do NOT search the web.

Text to check (paste or upload a .txt/.docx)

Sources to compare against — paste URLs or raw text, one per line (optional)

Shingle size (word n-gram)

Min match length (words)

No check run yet. Provide text and (optionally) sources to compare.

Overall similarity: —

Highlighted Source (matches in red)

—

Notes: Client-side checks are great for comparing against known sources and catching copy-paste. For full web-wide plagiarism detection use a professional service (Copyscape, Turnitin, Unicheck). I can add API integration placeholders if you want — you'll need an API key and usually a server-side proxy for CORS/security.

What is Plagiarism and Why Should You Avoid It?

Plagiarism is using someone else’s work or ideas without giving proper credit. It can be intentional or accidental, but the consequences can be severe:

Academic penalties, including failing grades
Professional reputation damage
Loss of trust from readers or customers
Potential legal issues in commercial contexts

Even if you don’t copy directly, rephrasing too closely without acknowledgment can still be considered plagiarism. In short, originality is not just a matter of pride — it’s a necessity.

Why Use This Plagiarism Detector?

There are countless plagiarism checkers online, but many come with drawbacks:

Privacy concerns – Some tools store your content on their servers.
Costly subscriptions – Many require payment after a few uses.
Slow performance – Cloud-based services can take minutes to analyze text.

This plagiarism detector solves those problems.

Key Benefits:

1. Privacy-First Approach

Your text stays on your device for local checks. It never gets uploaded to unknown servers unless you intentionally connect to an external API.

2. Instant Results

Because it runs in your browser, there’s no waiting for long processing times.

3. No Sign-Up Required

You can start checking right away — no accounts, passwords, or verification emails.

4. Multiple Input Methods

Paste text directly, upload files (.txt, .md, .docx), or paste full reference sources for comparison.

5. Flexible Settings

Adjust shingle size and minimum match length to customize detection sensitivity.

6. Self-Plagiarism Detection

Checks for repeated content within the same document — useful for ensuring variety in your writing.

7. Portable and Offline

Can be embedded in blogs, personal websites, or educational portals, working even without constant internet access for local checks.

How to Use the Plagiarism Detector – Step-by-Step Guide

Let’s walk through exactly how to use the tool from start to finish.

Step 1 – Input the Text to Check

Paste your text into the "Text to check" field.
Alternatively, upload your file (.txt, .md, or .docx) using the Upload option.

💡 Example: If you’re checking a blog article, paste the entire draft.

Step 2 – Provide Comparison Sources (Optional but Recommended)

This step boosts accuracy by giving the detector something specific to compare against.

Paste URLs, full text excerpts, or documents you suspect may have overlapping content.
If you don’t provide sources, the tool will check for self-plagiarism (repetitions within your document).

Step 3 – Adjust Detection Settings

Shingle Size – The number of words in each group compared. A shingle size of 6 is recommended for balanced accuracy.
Min Match Length – Minimum number of words for a similarity to be considered significant. Default is 8.

Step 4 – Run the Check

Click "Run Local Check". The tool will process your text instantly and show:

Overall similarity percentage
Bar graph visualization
List of matching sources
Extracted matching phrases
Highlighted text preview

Step 5 – Review the Results

The report shows:

Which source had the highest similarity percentage
How many matches were found
The exact text segments that matched
A color-coded highlight of similarities in your text

Step 6 – Save or Share the Report

You can:

Copy Report (JSON) – For saving a digital record or integrating into other tools
Download Report – Stores the report as a JSON file on your device
Clear – Resets the tool for a fresh check

Manual – Detailed Feature Overview

Here’s what each part of the tool does, explained in plain language:

Text to Check Field – Where you paste or upload your main content.
Sources to Compare Against – Optional; helps find external matches.
Shingle Size – Controls sensitivity; smaller numbers detect more matches but may flag unrelated similarities.
Min Match Length – Avoids false positives by ignoring very short overlaps.
Run Local Check – Analyzes text instantly using browser-based computation.
Copy JSON Report – Saves results in a structured data format.
Download Report – Generates a file you can store or share.
Clear – Resets all fields and results.

Tips for Accurate Plagiarism Detection

Provide Full Sources for Comparison
The more reference material you include, the better the results.
Avoid Checking Only Short Excerpts
Longer text gives more accurate similarity measurements.
Adjust Settings for Your Needs
- Academic writing: Higher min match length to avoid false alarms.
- Creative writing: Lower settings to catch even small overlaps.
Run Multiple Checks
Compare your document against different sets of sources.
Don’t Rely Solely on Percentage
Read through the matches — some may be common phrases, not actual plagiarism.

Common Mistakes to Avoid

Thinking the tool searches the entire internet automatically – For that, you need an external plagiarism API integration.
Skipping the source upload – Without comparison sources, external plagiarism won’t be detected.
Misinterpreting short matches – Not all overlaps mean copying. Some phrases are naturally common.
Forgetting to cite sources – Even if detected matches are small, always give credit.

Why This Tool is Different from Other Plagiarism Checkers

Unlike popular plagiarism checkers like Turnitin or Grammarly:

You own your data – No cloud storage.
No recurring costs – One-time setup on your blog or site.
Works offline – Perfect for secure environments.
Open customization – You can modify settings and add API connections later.

Frequently Asked Questions (FAQ)

Q1: Does this tool detect plagiarism from the entire internet?

Yes, but you’ll need an API key and possibly a server-side proxy.
