We don't ask you to trust us. We ask you to trust the math. Our zero-knowledge architecture ensures that not even Writtt can access your data.
We don't ask you to trust us, we ask you to trust the math. Our zero-knowledge architecture ensures that not even Writtt can access your data. Here's how it works: what you type exists only in your browser's memory, and readable text never touches the network. Everything is shielded in your own browser with AES-256-GCM before anything is sent. What reaches our servers? Only the encrypted blob, which without your master password is nothing but meaningless noise.
Your words are safe in an unbreakable vault. This is not a marketing promise — it's applied cryptography. Every byte you write is transformed into cryptographic noise before leaving your browser. The key? It only exists in your head.
Writtt Pro is not just an editor — it's a complete ecosystem to write, store, and protect. Every module is built with zero-knowledge encryption from the first byte.
Professional WYSIWYG editor with Markdown, syntax highlighting, tables, task lists, and focus mode. Everything you expect from a premium editor — with the difference that every character is encrypted before leaving your browser.
Upload, preview, and organize files — PDFs, images, documents — inside a vault with native E2E encryption. The server stores only cryptographic blobs. Not even we know what you stored.
2FA via TOTP, trusted devices, configurable auto-lock, and emergency recovery key. Security is not an optional feature — it's the foundation of every module.
GPT-4, Claude, and Gemini right from the editor. Communication is browser → provider. Writtt never sees the content.
Web, desktop, and mobile. Encrypted sync across devices.
Vector PDF, native Word, Markdown. Your data, your format.
Restore previous versions — all stored encrypted.

Content exists only in your browser's memory. Readable text never touches the network. Never. No HTTP request, no WebSocket, no logs — nothing leaves without being encrypted first.
AES-256-GCM encrypts every character with a key derived from your password via Argon2id (64MB memory, 3 iterations, parallelism 2). The key never leaves your device.
Only the encrypted blob reaches our servers. Without your master password, this data is nothing but meaningless noise. Not us, not hackers, not governments can read it.
The same encryption standard used by governments, banks, and intelligence agencies to protect classified information.
Key derivation with 64MB memory, 3 iterations, and parallelism 2. Resistant to GPU, ASIC, and rainbow table attacks.
The server stores only encrypted blobs. Even if breached, the data is noise — without the key, there is no content.
Two-factor authentication via TOTP, trusted devices, configurable auto-lock, and emergency recovery key.
