Bring the book only you can write all the way home.
Start with a manuscript, or start with what you know. Wordhaven helps you find a clear direction, test how the book lands, and strengthen it in your own voice—with nothing changed without your approval.
Choose the path that matches where you are. You can change direction later.

How Wordhaven works
How Wordhaven works
Three steps. No prompt engineering. No dashboards to configure.
1. Upload your manuscript
Paste your Amazon listing and first chapter for a Quick Reader Test. Upload the full book for a Full Manuscript Review. Accepted: DOCX, PDF, EPUB, plain text.
2. A genre-matched reader panel reads it
A simulated reader panel calibrated to your genre reads your work with the same instincts a real audience would bring. Not a grammar pass. Not a plot summary. A read.
3. You get a report you can act on
For an opener: buy-intent, hook clarity, and the specific objections readers raised. For a full book: an estimated pacing curve, predicted finish rate, an ending payoff signal, and a prioritized list of what to fix, in the order that most improves your book.
Your manuscript is not used to train AI models. It stays yours.
The four rooms
Wordhaven is not a SaaS.
It is a place.
The Study
The workspace.
Your quiet place to plan, draft, and shape your book. Every manuscript, every version, every reader report, organized by project.
Open your study →The Desk
The editing workflow.
Where your manuscript moves through four focused passes: developmental edit (structure and arcs), line edit (rhythm and voice), copy edit (mechanics), and final proofread (one clean, publication-ready pass).
See the editing pipeline →The Reader Room
The reader panel.
Where a simulated reader panel, calibrated to your genre, reads your manuscript and reports back: predicted finish rate, buy-intent, ending payoff signal, and what the readers who abandoned said on the way out.
Run a Reader Test →Library
Your permanent shelf.
Every draft, every report, every version, kept and searchable. Nothing you generate here is lost.
