eDoC is a versatile code editor designed for both online and offline use, incorporating Dropbox and local file integration. It is built on the Ace Editor framework, offering robust features like syntax highlighting, syntax checking, and autocompletion, enhancing the coding experience. The user interface includes a preview editor that visually reflects changes made in real-time, allowing users to see the effects of their edits immediately.

The application supports multiple coding modes, including single, dual, and quad views, all of which are resizable and independent. A notable feature is the web development preview window, which integrates Chrome's 'inspect element' functionality. Although it currently supports only inline scripts and styles, future updates aim to expand language modes and enhance integration with platforms like Google Drive and GitHub.
