# reusable character library for consistent AI video — spoolcast A reusable character and prop library — the World Kit — so a person or object looks the same in every shot of a video, and in every video of a series.

A character's look lives in one record that every shot reads, so correcting it once corrects it everywhere. Shots list every character on screen, which stopped the model from drawing a stranger when someone was mentioned but not listed. **Built with** Python, kie.ai for image generation, Cloudflare R2 for reference storage, React + TypeScript front end. ## Links [Site or demo]() Status and dates describe the published record, not a recent test of an external service.
