Character Bible vs Story Bible vs Character Sheet
These three terms get used loosely, and it's easy to assume they're interchangeable. They're not — each solves a different part of keeping a character consistent, and understanding the difference helps you figure out what you actually need.
Story bible
A story bible (also called a series bible) is a broader worldbuilding document — plot, timeline, setting rules, and character notes for an entire story or series, usually kept as text. It's the reference a writer or writing team uses to stay consistent across a long project. It's almost entirely written, not visual, and it covers far more than any one character.
Character sheet (or model sheet)
A character sheet — also called a model sheet or turnaround sheet, borrowed from traditional animation — is a single image showing a character from multiple angles and expressions, used as a visual reference for artists, animators, or 3D modelers. It's purely visual and scoped to one character's appearance.
Character bible
A character bible sits between the two: it's a per-character reference that combines a visual reference set (like a character sheet) with written notes — personality, backstory, voice — the way a story bible does, but scoped to a single character rather than a whole story. Character Bible (the tool) generates both halves: the multi-angle, multi-expression image set with a consistent face, and an editable personality/backstory profile saved alongside it.
Frequently asked questions
Do I need all three?
Not necessarily. A solo project with one main character might only need a character bible. A multi-book series with a large cast typically needs a story bible for the overall world, with a character bible or character sheet for each major character.
Can Character Bible replace a story bible?
No — a story bible covers plot, setting, and timeline across a whole project, which is outside what a per-character tool does. Character Bible covers the character-level layer: consistent visuals plus personality and backstory for each individual character.
Does the character sheet Character Bible generates include written notes too?
The exported character sheet (model sheet) is image-only, matching the traditional meaning of the term. The written personality/backstory profile is saved separately in your library, alongside the images, not baked into the exported sheet file.
