Key Features ✨

• Simplicity First: The entire application is a single HTML file. No builds, no installations. Just download the file and open it in your browser to get started.
• Zero Dependencies: Written in pure HTML, CSS, and vanilla JavaScript. This means it's fast, lightweight, and incredibly robust.
• Fully Local & Private: All your data—prompts, folders, and tags—is stored directly in your browser's IndexedDB. Nothing is ever sent to a server, giving you complete privacy and offline access.
• Advanced Encryption: For an extra layer of security, you can password-protect individual prompts or entire folders. The content (body and notes) is encrypted using the strong AES-GCM standard from the Web Crypto API. Passwords are never stored and are required for each session, ensuring only you can access your sensitive data.
• Responsive & Mobile-First UI: The interface is designed to be beautiful and functional on any device. The mobile experience feels native with a morphing Floating Action Button (FAB), intuitive back-button navigation, and a dedicated search interface.
• Powerful Organization:
  • Folders: Group your prompts into folders. A settings menu (visible on hover) allows you to easily Rename, Lock/Unlock, Export, or Delete any folder.
  • Advanced Tag Management: Add multiple tags for flexible organization. A dedicated manager lets you globally rename or delete tags, automatically updating them across all associated prompts.
  • Favorites: Mark your most-used prompts for quick access.
• Robust Data Management:
  • Flexible Import/Export: You are always in control. Easily back up your entire database or import it to another device. You can also export just a single folder or a selection of multiple prompts.
  • Bulk Actions: Select multiple prompts at once to move, delete, or export them in a single action, saving you time.
• Efficient Workflow:
  • Drag & Drop: Instantly move a prompt into a new folder by simply dragging it from the list and dropping it onto the folder in the sidebar.
  • Powerful Search: Instantly find any prompt by searching its title, body, notes, or tags. The search even works on decrypted content during a session.
  • Sort & Find: Sort your prompt list by creation date or title, and use the "Back to Top" button for long lists.
  • Resizable Layout: Adjust the view by dragging the divider between the prompt list and the editor.
  • Quick Copy: A convenient one-click button copies the prompt's body to your clipboard.
  • Character Counter: Keep track of your prompt's length with a real-time character counter.
  • Fullscreen Editor: Expand the prompt or notes fields into a distraction-free fullscreen editor for focused writing.
