The encrypted writing workspace for novelists and journal-keepers. Zero-knowledge encryption keeps your manuscript private. Free to start, Pro from $7/mo.
Grounded in available product and source data
CipherWrite is the private writing app for authors. Draft, outline, and finish your manuscript with built-in AI — protected by zero-knowledge encryption, so your unpublished work can never be read, leaked, or used to train AI. Start free.
In an age where every keystroke is shared, tracked, and graded by opaque algorithms, writing in a conventional cloud editor means your most private creative work is being scanned for patterns and commercial data points.
We believe the most important thoughts are the ones you can't yet say out loud—the raw fears, the honest confessions, and the early book drafts that truly define your human experience.
CipherWrite was built specifically to serve as a secure writing software sanctuary where you can finally be completely alone with your own mind without the intrusion of AI training or predatory growth hacks.
As a premier free book writing app, we offer a blank page that respects your privacy as a fundamental human right through robust client-side keys and absolute zero-knowledge encryption.
We don't just "encrypt" data. We built an architecture where your words are physically isolated from our server's eyes.
Encryption keys are forged in the fires of your machine. They never touch the wire.
No server logs. No metadata tracking. No search history. Your path through the vault is invisible.
