Know how your novel will land — before you publish it.
Wordhaven is a manuscript intelligence platform for novelists. A simulated reader panel matched to your genre reads your book, five editorial passes refine your prose, and you finally see your manuscript the way an audience will.

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: a chapter-by-chapter engagement heatmap, drop-off flags, 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 is edited across five distinct passes: copy edit (mechanics), line edit (rhythm and voice), developmental edit (structure and arcs), business edit (commercial hook and positioning), 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: engagement heatmap, pacing and drop-off flags, buy-intent, ending payoff signal.

Your permanent shelf.
Every draft, every report, every version, kept and searchable. Nothing you generate here is lost.
