How the Novel Builder Works
Blueprint Your Chapters
Start with guided questions that surface protagonist goals, stakes, and setting tone. The builder assembles a chapter-level outline you can edit at any time.
- •Aiden Mercer returns to Graywater and unlocks his late father's farmhouse under a slate sky.
- •Nightfall brings scratching behind the bedroom wall and the smell of rot in the attic.
Lock Beats Before You Draft
Each chapter becomes a stack of editable beats. Approve, reorder, or regenerate before any prose is written to keep tension consistent.
Beat 1 — Arrival Under the Water Tower
Goal: return home; conflict: looming memories; outcome: Aiden keeps driving despite the dread that tightens his chest.
Beat 4 — Night's Scratching
Conflict: faint scraping inches from the headboard; emotion: exhaustion turns to alert dread as sleep evaporates.
Generate Prose That Matches The Plan
Stream chapter prose in the desktop app or cloud editor, pause on any paragraph, and punch in revisions without losing continuity.
