Characters with depth, locked into your world
Build detailed characters with portraits drawn from your picks, Big Five personality scores, and visual presets. Every physical trait goes into the Story Bible and is checked in every chapter.
- Portraits drawn from visual presets -- body, skin, hair, eyes, outfit
- Big Five personality scores the writer reads for every scene
- Relationships and backstories recorded in the Story Bible
Every chapter is read against your Story Bible
Physical traits, timelines, world rules, relationships, and character deaths are checked before and after every draft. A contradiction is patched in place or the chapter is rewritten; a fact error that survives is blocked, not shipped.
- Contradictions patched or rewritten before you see them
- Must-appear facts verified with deterministic + semantic checks
- World rules scanned in every chapter, at chapter 80 as at chapter 8
Map your world, lock your lore
Create locations on an interactive canvas, define factions, set world rules. All of it goes into the Story Bible the writer reads, so the prose matches what you built.
- Canvas map with places, connections, roads, and labels
- World rules and magic systems checked in every chapter
- Factions, geography, and the story clock tracked automatically

Three breaks caught by enforcement
A LitRPG with fourteen hard magic rules. Every chapter is scanned against the rules the author wrote, so a spell cost or a cooldown cannot quietly change in chapter 30.
Hard magic systems
World rules checked after every draft
A weekly serial whose readers find the errors first. Dead characters are blocked before the chapter is written, and a changed eye colour is patched, or the chapter rewritten, before it is posted.
Weekly serials
Fact errors blocked, not shipped
Two series that must never bleed into each other. Each project keeps its own Story Bible, so names, factions, and timelines are checked against the right canon.
Several series at once
One Story Bible per project
