CipherWrite

CipherWrite is a privacy-first writing and journaling app with true end-to-end, zero-knowledge encryption, designed for novels, private journals, and long-form writing that only you can read. It runs as a free, cross-platform PWA on Web, Mac, Windows, Linux, iOS, and Android, with client-side keys, anonymous sync, and no trackers or AI training on your data. CipherWrite adds optional, boundaries-respecting AI for brainstorming and editing, plus tiers from a free local-only plan to pro and enterprise options with encrypted cloud vaults, AI credits, image uploads, and self-hosted deployments
