Everything You Need to Write Fearlessly
CipherWrite combines zero-knowledge encryption with powerful AI writing tools. Every feature is designed to protect your words and enhance your craft.
Zero-Knowledge Encryption
Your manuscript is encrypted on your device before it ever reaches the cloud. The key is derived from your password, so even we cannot read your words — and no AI can train on them.
