Craft Deeper Characters, Build Cohesive Worlds

H-CAToolkit turns character psychology, narrative structure, and worldbuilding research into structured tools for creators. It is also where Calculogic began—a broader field, form, quiz, and logic builder growing from the needs those tools revealed.

What Is H-CAT?

H-CAToolkit is a collection of psychology-informed tools for developing characters, stories, and fictional worlds. It began as an attempt to make the connections between character psychology and narrative structure explicit enough to turn into useful forms instead of leaving them implicit.

Building those tools led to Calculogic, a more general system for creating fields, forms, quizzes, knowledge, results, and logic. H-CAT remains the creative toolkit and original use case; Calculogic is the broader builder growing from that work.

Holistic Character Forms & Templates

Explore structured prompts for character identity, appearance, psychology, relationships, narrative roles, and backstory. These resources are designed to make important creative connections easier to see and consider—not to prescribe one correct way to build a character.

Selected H-CAT Resources

Browse forms and reference material from H-CAT’s earlier development. Some resources reflect previous stages of the project, but they remain part of the research and creative foundation Calculogic grew from.

H-CAT is a solo project right now. There’s no community to join yet, but the blog is the best place to follow its development.
