Overview
The Notepad is a persistent multi-note text editor that saves all notes automatically to your browser’s localStorage — meaning your notes survive page refreshes and browser restarts. It features a sidebar for managing multiple notes, a formatting toolbar, and word/character counting.
How to Use
Click + in the sidebar to create a new note. Click any note in the list to open it. Start typing — notes save automatically within 600ms of your last keystroke. Use the toolbar to insert Bold (**text**), Italic (_text_), Headings, Lists, Checkboxes, date stamps, and time stamps. Keyboard shortcuts: Ctrl+B for bold, Ctrl+I for italic, Tab for indent. Click Export to download as .txt.
Background & Context
localStorage is a browser-based key-value storage system introduced in HTML5 that allows websites to store up to ~5MB of data per domain locally on a user’s device without expiry. Unlike cookies, localStorage data is never sent to a server, making it ideal for private personal tools. Note that localStorage data is browser and device-specific — notes will not sync across devices.
