Is Copykiller - 표절부터 AI생성검사까지 safe?

Clean risk

Copykiller sends user-selected page text to copykiller.com for plagiarism and AI-generation checks after submission.

On any page, selecting at least 60 characters shows a Copykiller button that can move the selected text into the extension side panel. If the user submits the form, the text is sent as multipart form data to Copykiller's upload API for analysis.

Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
