Most books die in the middle — not for want of a corkboard. CipherWrite gives you a real writing workspace, an encrypted story bible, and The Finisher: an agent that notices when you stall and gets you back to the page. Every word is encrypted on your device, so your unpublished book can never be read, leaked, or used to train AI. Start free.
The lighthouse had been dark for eleven years, and still she climbed it every Sunday, as if the light were only late.
Her mother's letters were in the tin under the third stair — forty-one of them, none opened, all addressed in the same impatient hand. Ada had promised herself she would read one a year. She was, by her own arithmetic, thirty behind.
Tonight the sea lay flat as a held breath. She set the tin on the sill, and for the first time she did not put it back.
This is your novel on our servers. Without your key it stays exactly like this — for us, for staff, for anyone who ever asks.
Not because the writer lacked a plot outline, a corkboard, or a place to store character eye colours. Because one Tuesday they did not open the file, and then it was March.
The Finisher is an agent that remembers why you started, notices when you stall, names why, and hands you the next scene. It will not write your book. It will make sure you keep coming back to it.
It remembers you, not your book. The agent is never given your manuscript — not the text, not a summary, not an outline. Your chapters are encrypted in your browser with a key we do not have. What it knows is what you typed into a check-in on purpose, and you can read and delete all of it.
Five minutes of questions about your actual week — not a fantasy schedule. It ends with an if-then plan anchored to a real day, and the date you are aiming at.
Four days without words is the moment most books die. The check-in arrives then, and it opens by asking about the exact thing you committed to last time.
Not a streak counter. It knows the shape your stalls take, because you told it, and it hands you back the next scene so you never open a blank page wondering where you were.
In an age where every keystroke is shared, tracked, and graded by opaque algorithms, writing in a conventional cloud editor means your most private creative work is being scanned for patterns and commercial data points.
We believe the most important thoughts are the ones you can't yet say out loud—the raw fears, the honest confessions, and the early book drafts that truly define your human experience.
CipherWrite was built specifically to serve as a secure writing software sanctuary where you can finally be completely alone with your own mind without the intrusion of AI training or predatory growth hacks.
As a premier free book writing app, we offer a blank page that respects your privacy as a fundamental human right through robust client-side keys and absolute zero-knowledge encryption.
Every writing app says it takes privacy seriously. Here is what that means for your unpublished book in the three situations that would actually matter.
If we are breached
Your chapters and your story bible are encrypted on your device before they are saved. An attacker with our whole database has unreadable text, your email address, and timestamps. The key that opens it was never on our servers to steal.
If we are subpoenaed
We comply with valid legal process — and what we can produce is your account email, your billing history, and the encrypted file. No key escrow, no master key, no recovery backdoor. Not a promise not to look: we do not hold the thing that would let us.
If we are acquired
A new owner inherits documents they cannot read, because your key was never ours to transfer. And export to Word, EPUB, PDF and Markdown stays free on every plan — a manuscript you cannot get out intact is a hostage.
And if you would rather we were not in the loop at all: Pro lets you bring your own Google AI key, and the editor's AI then talks to Google straight from your browser — your key, your quota, and no request of ours to log. Your book is encrypted with a key we do not have, and your AI requests never reach us at all. There is not much left for us to know.
We've stripped away the noise and added layers of silence. The result is a writing sanctuary that feels as private as your own mind.
Absolute Privacy
Your Identity is hashed. Your words are encrypted. Not even the CipherWrite team can see what you write inside the vault.
Adaptive Creative AI
Brainstorm creative book ideas, detect private metadata leaks, and humanize your drafts with built-in AI writing software that respects your boundaries. Cipher Write is designed for authors, by authors.
Zero Knowledge
Encryption happens on your device. Only you hold the keys. No corporate cloud, including CipherWrite, has access to your raw text.
Stateless Sync
Sync your work across devices using encrypted payloads. CipherWrite sync is secure, fast, and completely anonymous.
Local-First
Encryption Core
Unlike other apps, the Cipher Write encryption keys never exist on our servers. Even if we were compromised, your data remains an unreadable mist.
17 outline templates — eight story structures and nine genre starter kits, from Save the Cat and the Hero's Journey to romantasy, mystery, horror and memoir.
Every beat arrives with the job it does, the questions that plan it, the way it usually fails, and where it lands in your word count. Apply one and it also seeds the story bible cards that genre needs — the magic system, the clue ledger, the two wounds.
The Three-Act Structure and the Non-Fiction Book Kit are free on every plan — apply one, fill it in, keep it.
“Midpoint at 50%” is abstract at 2am. Set your target length and every beat carries a real number — the reversal lands around word 40,000 in an 80,000-word novel.
One click turns any planned beat into a real chapter with your own plan waiting at the top of it. The outline stops being a document nobody opens.
An outline gives away the ending in a hundred words. Yours is encrypted on your device with your project key before it syncs — we cannot read it either.

Tier Privileges
Pro is not competing with our free plan. It is competing with the alternatives below.
| Option | Cost | Wait | The catch |
|---|---|---|---|
| Beta reader (swap or volunteer) | Free | 2–6 weeks | Quality varies enormously, and you owe them a read back. Many never finish. |
| Paid beta reader | $50–$300 | 2–6 weeks | One reader, one opinion. You cannot ask them to read it again after you revise. |
| Developmental edit (80k words) | $2,400–$6,400 | 4–12 weeks | The gold standard, and genuinely better than any AI read. Most writers cannot afford it per draft. |
| CipherWrite Pro | $10.57/mo | Minutes | It is not a human. A great developmental editor will still beat it — but you can run this on every draft, and it never gets tired of you. |

CipherWrite operates on absolute zero-knowledge encryption principles, meaning your creative work and private journals are secured before they ever leave your device. We use AES-256 encryption — the very same cryptography standard trusted by global financial institutions, military organizations, and security agencies worldwide.
Zero-knowledge means exactly what it says: our servers, our developers, and any potential intruders literally have zero knowledge of your content. When you type in CipherWrite, your words are scrambled using a unique key derived from your personal password. This key never traverses the internet and is never stored on our database. Even if subjected to a data breach, your files remain completely inaccessible ciphertext.
Unlike conventional cloud editors that scan your text to train AI models or serve targeted advertisements, CipherWrite ensures your raw, unfiltered thoughts remain entirely your own. Your intellectual property is technically and mathematically locked, giving you the ultimate peace of mind.
Perfect for drafting your "ugly first drafts" without fear of accidental exposure. CipherWrite is the leading free book writing app for authors who want to protect their intellectual property long before publication.
Process your emotions, fears, and honest confessions in a truly secure digital diary. It acts as a digital vault for your mental health and personal growth reflections, far away from algorithmic prying eyes.
Protect sensitive sources, confidential research, and whistle-blower information. Your notes traverse across devices seamlessly while remaining entirely locked behind robust mathematical encryption.

AES-256 encryption protects over 10 billion files globally for governments, banks, and enterprises. CipherWrite brings this exact invisible armor to your personal writing app, ensuring your words remain yours forever.
Got questions? We've got answers.
What makes this different from Google Docs or Notion?
Privacy. When you write in those apps, your text is sent to their servers where it can be scanned, analyzed, or leaked. CipherWrite ensures your words stay on your device and are encrypted before they ever touch the cloud. The Cipher Write team literally cannot see what you write.
Is this good for writing a book?
Absolutely. Many authors use CipherWrite (also known as Cipher Write) for the 'ugly first draft' phase because it's distraction-free and safe. You can organize chapters, export to PDF/Word, and write without the pressure of anyone watching.
How does the privacy actually work?
It's simple: You hold the key. When you set a password, it locks your data on your phone/laptop. If we (or a hacker) looked at our database, we'd just see scrambled nonsense. Your private thoughts remain private.
Can I get my data out?
Yes, always. You can export your notes to PDF, plain text, or Markdown at any time. It's your work, not ours.
Is there a free version?
Yes. You can write unlimited notes for free. We only charge for advanced features like cloud sync storage beyond a certain limit and multiple device management.
