Character Builder
A cast your chapters never forget
Build every character once. The outline and every chapter use the same profile, so names, motives and habits hold from page one to the end.
- 13-field profiles
- Write them yourself or generate with AI
- Free on every plan
Keep the cast straight
Without it
- A side character changes eye colour in chapter 9
- You re-explain who everyone is in every prompt
- The villain's motive drifts until it stops making sense
With it
- One profile per character, used by every chapter
- The outline plans scenes around real motives and conflicts
- Change a character once and the next chapters follow
