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 validates the originality of submitted text by displaying the specific source of flagged AI content in a clear, side-by-side comparison. Copyleaks' proprietary database, the Copyleaks AI repository, is built by capturing and archiving AI-written material from (1) published content: the internet, open access journals, and over 16,000 academic journals and (2) archived LLM outputs: millions of outputs generated internally by the Copyleaks data team via LLM prompting.
AI Source Match brings both parts of the Copyleaks report together to ultimately answer, with definitive proof, was this original?
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).
- 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 document/data go?
A: Copyleaks stores data on secure servers, which are primarily based on Google Cloud Platform, meaning 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 documents?
A: Yes, Copyleaks does "read" data in the sense that it needs to access and analyze the text submitted to check for plagiarism or AI-generated content; however, according to their privacy policy, they treat data as confidential and do not share it with anyone unless required by law, meaning they primarily use data to perform the plagiarism check and improve their service, not for any other purpose.
Q: Why can’t a document be uploaded?
