🔐 Powerful Features

Enterprise-grade encryption paired with simplicity

Security & Encryption

🔑 AES-256-GCM Encryption

Military-grade encryption using AES-256 in GCM mode. Every note is encrypted on your device before leaving your browser. We use PBKDF2 for key derivation with 600,000 iterations, making brute-force attacks impractical.

🌐 End-to-End (E2E)

The server never sees your plaintext. Your codeword derives the encryption key entirely on the client side using Web Crypto API. Even our infrastructure can't decode your notes.

✅ Zero Knowledge Architecture

We store only salted hashes of codewords for lookup, not the codewords themselves. Your data is encrypted at rest and in transit.

🛠️ Cryptography Stack

Algorithm: AES-256-GCM
Key Derivation: PBKDF2 (600k iterations)
Implementation: Web Crypto API (built-in browser)
Hash Function: SHA-256

Collaboration & Real-Time

👥 Live Collaboration

Multiple users can edit the same encrypted vault simultaneously. See live cursor positions, character count updates, and user presence indicators in real-time via WebSocket.

⚡ WebSocket Real-Time Sync

Changes propagate to all connected clients instantly. Users on the same codeword see updates as they happen, with latency monitoring built-in.

📊 Live User Count

See how many people are currently viewing/editing your vault. Perfect for coordinating feedback sessions or collaborative work.

Content & Media

🖼️ Image Embedding

Paste images directly with Ctrl+V or upload files. Images are embedded as base64 and encrypted the same way as text. Share screenshots, diagrams, mockups, and photos securely.

✏️ Rich Text Support

Format text with bold, italics, headers, lists, and code blocks. All formatting is preserved and encrypted.

📊 Character & Word Count

Live character and word count in the footer. Useful for tracking content length and staying within limits.

User Experience

📱 Mobile Optimized

Fully responsive design with touch-friendly interface. 48px+ touch targets for easy mobile interaction. Works on phones, tablets, and desktops.

🌓 Dark Mode

Toggle between light and dark themes. Your preference is saved in browser storage for future visits.

💾 Auto-Save

Changes save automatically every 2 seconds. You'll never lose work if your connection drops. All data is persisted encrypted on our servers.

🌐 No Login Required

Just enter a codeword and start. No registration, no passwords, no email verification. Perfect anonymity.

Advanced Features

📴 Offline Support (PWA)

Install as a Progressive Web App. Works offline with service worker caching. Background sync queues changes when reconnected.

📍 Latency Monitoring

Real-time latency indicator shows connection quality. Useful for understanding sync delays.

🔄 Browser Storage Persistence

Your theme and preferences persist across sessions via localStorage.
