What is Copyleaks Plagiarism and AI content checker tool in RefWorks?
Copyleaks is an online plagiarism and AI content detection tool that uses machine learning and natural language processing to compare submitted content with a large database of online sources.
This tool allows users to check if their manuscript contains plagiarized & AI generated content; it searches across a multitude of resources for each scan, including 16,000+ open-access journals, 1M+ internal documents and 20+ code data repositories.
Copyleaks is a first of its kind, patent-pending innovation tool that provides comprehensive analysis around why text has been identified as AI. Greater transparency, coupled with a deeper understanding of AI patterns and traces, empowers authenticity and originality.
How to access the Plagiarism and AI content checker tool:
You may access the Plagiarism and AI content checker feature in RefWorks via a dropdown menu under Tools:

FAQs
Q: What does this tool check for?
A: Copyleaks is an online plagiarism and AI content detection tool that uses machine learning and natural language processing to compare submitted content with a large database of online sources.
Q: What is AI Logic?
A: Copyleaks advanced detection engine that analyzes how a piece of content is written — not just what is written. This means it doesn't just flag similarities like traditional plagiarism detectors, but it:
- Detects AI-generated content (e.g., from ChatGPT or similar models).
- Understands writing patterns, structure, logic, and flow typical of AI vs. humans.
- Identifies content that has been paraphrased, rewritten, or otherwise manipulated to bypass detection.
- Recognizes logical progression and reasoning structures in the writing that match known AI writing styles.
Q: What is AI Source Match?
A: AI Source Match goes beyond simply detecting if content was AI-generated — it attempts to determine which specific AI model (like GPT-4, Gemini, Claude, etc.) likely created the content.
How It Works:
- Copyleaks' system compares the analyzed text to outputs from known AI models and uses pattern recognition, linguistic fingerprints, and machine learning classifiers to:
- Detect AI-generated content.
- Match it to a specific AI source or model.
- Indicate the likelihood or confidence level of the match.
Q: What is AI Phrases?
A: AI Phrases highlights specific phrases or segments in a document that are highly likely to be AI-generated.
This is useful when:
- Only parts of a document may be AI-written (e.g., mixed authorship).
- You need granular feedback on which parts were flagged.
How it works:
- The tool scans the document for AI-like writing patterns.
- It highlights phrases or sentences where AI authorship is suspected.
- These highlights help reviewers focus on questionable parts instead of re-reading the entire document.
Q: Where does my document/data go?
A: Copyleaks stores your data on their secure servers, which are primarily based on Google Cloud Platform, meaning your data is stored in Google's data centers, with backups kept on separate Google Cloud data centers to ensure redundancy and safety in case of a catastrophe.
Q: Can Copyleaks access and read my documents?
A: Yes, Copyleaks does "read" your data in the sense that it needs to access and analyze the text you submit to check for plagiarism or AI-generated content; however, according to their privacy policy, they treat your data as confidential and do not share it with anyone unless required by law, meaning they primarily use your data to perform the plagiarism check and improve their service, not for any other purpose.
Q: Why can’t I upload my document?
A: You either used all your available credits (1 credit = 250 words), or our pilot ended. If neither is true, check with Tech Support: https://help.copyleaks.com/hc/en-us.
Q: I didn’t have a chance to upload and check my paper, when will this be back?
A: We are evaluating responses and overall interest in this feature and will inform our users soon.
Q: Why don’t I see this feature in my RefWorks account?
A: Your institutional admin disabled this feature.
Q: How much does it cost to use the Plagiarism and AI checker?
A: In RefWorks, this feature is provided by Clarivate, but with a limited number of credits.
