Why writers stay
Depth first. Then the draft you keep.
Heavier than a line-level toy—on purpose.
Manuscript intelligence
The model sees your bible, map, and scene intent—so suggestions respect continuity and voice, not just the last sentence.
Quality over instant hits
Built for books people finish: fewer generic paragraphs, less rewrite debt than shallow assistants.
You stay the author
Nothing ships without you. Plan, draft, and export in one place—no scavenger hunt across chats.
How it works
Structure first. Then flow.
Bible → map → plans → prose. Each step feeds the next.
Step 1
Plot & chapter map
In the app this is called Architect
Acts, turns, and subplots become a chapter map—so drafting has direction.
- Subplots tracked across the book
- Each chapter has a clear job

Step 2
Story bible
In the app this is called Canon
Characters, places, lore, voice—one source of truth the AI reads first.
- World rules & relationships
- Feeds planning and drafting automatically

Step 3
Scene plans, then prose
In the app this is called Scene blocs
Short plans per scene: beats, mood, targets. Prose lands inside the frame.
- Human-sounding guardrails
- You approve every block
