Copy Có Nguồn is a free Chrome extension designed to streamline the process of copying text from web pages while preserving the source. This tool is particularly beneficial for marketers, content writers, students, and researchers who frequently compile information from the internet. With a simple right-click, users can copy text along with the page title, original link, domain, and timestamp, ensuring proper attribution and easy reference later.

In addition to its basic copying functionality, Copy Có Nguồn maintains a history of copied items, allowing users to review content and access URLs at any time. The extension supports multiple formats for copying, including compact, Markdown, and quotes, and allows users to add notes or delete individual entries. Operating locally within the browser, it respects user privacy by only saving content when prompted and does not require login credentials or external server uploads.
