OneBook is a Chrome extension designed to assist users in creating and storing notes while learning to code online. It simplifies the process by allowing you to refer back to these notes after watching coding tutorials, aiding in writing code in your preferred compiler. With OneBook, the need to constantly switch between tabs during video tutorials is eliminated, enhancing your learning experience.

To utilize OneBook, simply install the extension, capture screenshots, and record audio messages of specific parts of the video for reference. Extract code from the screenshots to better understand the logic, and later use these notes to write code efficiently after completing the video tutorial.
