End-to-end encrypted book writing app with accountability.




CipherWrite is a book writing application focused on privacy, craft development, and finishing long-form manuscripts. Most manuscripts stall midway through drafting, often because authors abandon their routine or worry about cloud editors indexing their work. CipherWrite addresses these challenges by combining distraction-free drafting spaces with structured pacing systems and a dedicated accountability agent called The Finisher.
What sets CipherWrite apart is its zero-knowledge, local-first security architecture. Manuscripts, outlines, and story bibles undergo client-side encryption using AES-256 before syncing to remote servers. Because users retain their private passphrases, the platform cannot read raw drafts, comply with content subpoenas, or feed unpublished text into machine learning training datasets.
Alongside strict privacy, the platform integrates craft-focused tools such as multi-perspective simulated beta readers, genre-specific beat sheets, and optional browser-direct artificial intelligence integrations that keep queries off intermediate servers.
CipherWrite is designed for novelists and long-form prose creators who prioritize confidential workspaces and structured completion aids:
CipherWrite provides a Free tier alongside monthly and yearly subscriptions. The Free plan includes end-to-end encrypted projects, encrypted story bibles, introductory AI assists, standard document exports (Word, EPUB, PDF, Markdown), and daily ten-minute craft drills. CipherWrite Pro costs $11 per month on monthly billing, $8 per month when billed quarterly (saving 27 percent), and $7 per month when billed yearly (saving 36 percent). Pro includes unlimited AI features, the ability to bring your own Google AI key, full access to The Finisher agent, five automated reader perspectives for manuscripts up to 80,000 words, private season cabins, and downloadable authorship PDF records.
Unlike Scrivener, which operates purely as a local desktop software without native browser-based end-to-end encrypted sync, CipherWrite enables encrypted cross-device work without third-party cloud workarounds.
Unlike Google Docs or standard cloud word processors, CipherWrite prevents third-party data analysis, refuses manuscript access to staff, and does not feed drafts into general machine learning models.
Can CipherWrite recover my files if I forget my passphrase?
No. CipherWrite uses zero-knowledge encryption, meaning your private key stays on your local device. Because no master keys or backdoors exist on the servers, lost passphrases cannot be recovered by staff.
Are my manuscript words used to train artificial intelligence?
No. All draft text is stored as encrypted ciphertext that cannot be viewed by the platform, making it impossible to index or feed into AI training pipelines.
