Zero-Knowledge Encryption
AES-256-GCM encryption happens entirely in your browser. The server never sees your content — not even we can read it.
Self-Destructing Documents
Set documents to expire after a time (5 minutes to 30 days) or a view count (1 to 10 views). They delete automatically.
Burn After Reading
One-time links that self-destruct after the first view. Perfect for passwords, API keys, and one-off secrets.
Password Protection
Add an optional password with PBKDF2 key derivation. Even if someone intercepts the link, they can't read the content.
Beautiful Code Editor
CodeMirror 6 with syntax highlighting for 10+ languages. Auto language detection, bracket matching, and proper indentation.
7 Stunning Themes
Xcode, Dracula, Monokai, Nord, Solarized, GitHub, and Olive. Dark and light modes with persistent preference.
Live Preview
Real-time Markdown rendering with GitHub-flavored syntax, HTML preview, and formatted JSON validation.
QR Code Sharing
Generate and download QR codes for any document link. Quick sharing from desktop to mobile with a single scan.
Use Cases
Share API Keys & Secrets
Send credentials to teammates with burn-after-reading. The link dies after the first view — no trace left.
Code Snippets
Share code with syntax highlighting for JavaScript, Python, Go, SQL, and more. Better than plain-text paste.
Onboarding Docs
Share environment configs, database credentials, or setup instructions that expire after the new hire reads them.
Confidential Notes
Password-protect sensitive meeting notes, legal documents, or personal information with a time-limited link.
Built With
