For authors

BlindProof is for anyone writing a book who may one day need to show, beyond argument, that they wrote it themselves — over months, in their own hand, without help from a machine. It works quietly while you write, keeps your manuscript entirely to itself, and produces a single document at the end that your publisher can check on their own.

These pages explain what BlindProof does and how to use it, in plain terms. No technical background assumed.

Start here

  1. How it works — the idea behind the product, in the kind of language you'd use to explain it to a friend.
  2. The proof bundle — what you hand your publisher, and what they do with it.
  3. Setting up — the one-time steps: choosing a passphrase, keeping your recovery sheet safe.
  4. Everyday use — which is to say, nothing. You write as you always have.
  5. If things go wrong — lost passphrase, new computer, BlindProof disappearing. What each of those actually means for you.
  6. For publishers — a short page you can send to your editor ahead of delivery, so they know what's coming.

What BlindProof is not

BlindProof does not read your manuscript. It does not send your manuscript anywhere. It does not decide whether your book is good, or whether you wrote it "enough by yourself". It simply records, in a way no one can tamper with, that the book you deliver is the book you were working on all along — not something assembled overnight. The judgment of what that evidence is worth belongs to you and your publisher, not to us.
