[PC Notepad is a fast, distraction-free online notepad built for both desktop and mobile users. It opens instantly, works offline after the first visit, and saves notes locally on your device with optional AES-GCM password protection. The app features no login requirements, multi-tab support, export options (TXT, DOCX, PDF), markdown preview, zen mode, and PWA functionality for installation as a desktop/mobile app. It's designed with privacy-first principles - no servers process your content, making it ideal for sensitive notes and quick drafts. The clean, professional interface rivals premium tools while remaining completely free and accessible.]
