Sheaf is a calm, local-first writing studio for novelists. Your manuscript lives on your device the instant you type it, syncs across everything when you want it to, and can be locked so only you can ever read it.
No account needed. Nothing to install.
No AI — your words never train a modelNo subscription — pay once for syncLocal-first — yours, offline
Yours, offline-first
Write with no account and no connection. Every keystroke is saved on your device immediately — your words never depend on someone else's server.
Sync when you want
Turn on optional cloud backup and pick up on any device, mid-sentence. Off by default — you choose when your writing leaves the room.
Private by design
Vault mode encrypts everything end-to-end with a key only you hold. Not even we can read your manuscript — zero-knowledge, for real. And no AI here either: your words never touch a model, let alone train one.
Made for long-form
A binder that holds your whole book — scenes and chapters, character cards, version history — and a quiet, distraction-free page built for the long haul. And when the draft is done, the publishing suite turns it into a store-ready book.
