Your sources deserve
better than the cloud.
Investigative notes stored on cloud services can be subpoenaed, breached, or silently scanned. Writtt keeps your words on your device, encrypted with AES-256, making zero network calls. Source protection isn't a feature — it's the architecture.

Subpoena vulnerability
Cloud providers can be legally compelled to hand over your notes, drafts, and metadata — often without notifying you first.
Silent telemetry
Most editors track your writing patterns, document titles, and session length. That metadata alone can reveal your sources.
Data breach exposure
When your notes live on someone else's server, a single breach can expose years of investigative work and confidential contacts.
Built for source protection.
AES-256 encrypted vault
Every sensitive document is individually encrypted with military-grade AES-256-GCM. Without your password, files are indistinguishable from random noise.
100% local storage
Your notes never touch a server. No cloud sync, no remote backup, no third party ever holds your data. Nothing to subpoena.
Works offline — always
Write in the field, on planes, in locations where connectivity itself is a risk. Writtt makes zero network calls at runtime.
Zero telemetry
No analytics, no usage tracking, no document metadata collection. We don't know what you write, when you write, or how often.
“There is no investigative journalism without source protection. And there is no source protection on someone else's server.
Frequently asked questions
