Books aren’t written in one sitting, and they shouldn’t be proven that way either. A manuscript is a living project you come back to — so ValidDraft keeps the whole writing journey together, from the first line to the last chapter.

Prove you wrote the whole novel
A single page check was never enough for a book. Manuscripts lets you write the entire thing — chapter by chapter — and finish with one certificate that says a human wrote all of it.
What it’s for
When an agent, a publisher, or a contest asks “did you really write this?”, a book-length manuscript with a genuine writing history answers before you have to. It’s proof that grows alongside your work — no extra step at the end.
One project
All your chapters live together, not scattered across pages.
Write over time
Come back day after day; your history stays intact.
One certificate
Finish with a single, shareable proof for the whole book.
Start your manuscript
Open a new manuscript, write the first chapter tonight, and let the proof build itself as your book grows.
Begin a manuscriptFrequently asked questions
What are ValidDraft Manuscripts?+
A long-form workspace built for authors. Instead of proving a single page, you write your whole book across chapters inside one tracked project and finish with a certificate covering the entire work.
Do I have to write my whole book in one sitting?+
No. A manuscript is meant to grow over days, weeks, or months. You return to it chapter by chapter, and ValidDraft keeps the writing history together as one project.
Who is Manuscripts for?+
Novelists, non-fiction authors, screenwriters, and anyone producing book-length work who wants clear, ongoing proof that a human wrote it — for agents, publishers, or their own peace of mind.
How is this different from checking one document?+
A single check proves one page. A manuscript captures the natural arc of a long project — many sessions, real revision, growing word counts — which is far harder to fake and far stronger evidence of genuine authorship.
