Why Check for Duplicate Content

Duplicate content can hurt your search rankings and credibility. CopyLeaks scans your text against billions of web pages and academic sources to find any matches, helping you fix problems before they affect your results.

Step 1: Upload or Paste Your Content

Create an account on CopyLeaks and start a new scan. Paste your text directly or upload a document in formats like PDF, Word, or HTML. You can also scan websites by URL to check entire published pages.

Step 2: Review the Similarity Report

Once the scan finishes, CopyLeaks shows a detailed report with a similarity percentage and highlighted matches. Click on each match to see the source. This lets you decide whether a rewrite is needed or whether the quote is acceptable.

Step 3: Detect AI-Generated Text

If you need to verify whether content was written by a machine, use the AI detector. Paste the text and run the check. CopyLeaks will indicate the likelihood that the content was created by AI, which is useful for editors reviewing submissions.

Step 4: Rewrite with the Paraphraser

For sections with high similarity, use the paraphraser to rewrite them. Enter the original text and let CopyLeaks generate alternative phrasings that reduce similarity while keeping the meaning. Then review and fine-tune the result.

Step 5: Integrate into Your Workflow

If you process many documents, use the CopyLeaks API or connect it to your LMS and content tools. This automates scanning so every piece of content is checked before publication.

Pro Tips

Scan content before publishing, not after, to avoid costly mistakes. Use the report to track a baseline similarity score over time. Combine the AI detector and paraphraser to ensure both originality and a human touch in your writing.

By making CopyLeaks part of your process, you can confidently publish original, safe content whether you are a writer, publisher, educator, or business owner.
