Secure Book: Private Note-taking Web App

Secure Book is a free private note-taking web application. It provides convenient WYSIWYG note editing and encrypted storage using aes-256 standard. I created this application on my own, by using a React-like library Preact, ProseMirror for content editing, Web Workers, unit tests, and other modern web technologies. In addition, I created a convenient documentation, explaining the architecture and how to develop the application. Oath 2.0 and GitLab API is used for authentication and data storage.
