Story planning

Character Bible
Build a reusable visual identity from silhouette, face, outfit, palette, signature traits and drawing notes.
Character drawing tools
Upload references or draw inside Kaijin while using Character DNA as a consistent visual brief.
Story Bible
Record places, power systems, cultures, objects, history and canon rules so the world stays coherent.
Chapter canvas
Compose panels, artwork, text and layers for manga pages or vertically paced manhwa and webtoon episodes.
Publishing preparation
Review the series cover, description, cast consistency, chapter status and reader-facing mobile flow.
Made for different starting points
Writer, artist, or somewhere in between.
Writers can establish visuals without pretending to be illustrators. Artists can keep continuity and production organized. Small teams can share a single source of truth for the series.
For writers
Move from prose and ideas into a visual production plan with consistent character references.
For artists
Keep story context, visual rules, layers and release preparation close to the canvas.
For small teams
Align around the same canon, cast details and chapter pipeline as the project grows.
Begin with the story
Your first project does not need to begin perfectly.
It needs a place where every decision can become clearer.
