CipherWrite — a zero-knowledge encrypted writing workspace for serious authors.
You write novels, memoirs and journals in a browser editor where the manuscript is encrypted client-side, so the text never reaches the servers in readable form. On top of that sits a paid craft layer: an AI Beta Reader that returns a real critique report, a writing coach, a story bible, book templates and real DOCX/EPUB/PDF/MD export — with BYOK so AI features run browser-direct against your own key and the prose still never touches us.

Built this after realising writers weren't just failing to finish — they were writing softer versions of the true thing, because the draft sat readable on someone's server. Chapters encrypt in your browser with a key I never receive. The trade-off is real: lose your passphrase and I can't recover your book, and Scrivener still beats us on compiling. Free tier is a genuine one.
