AI designed for SF
Science-Based Worldbuilding Auto-Design
Logically builds social structures, physics, and economic systems matching the story's technology level.
Tech Level & Social Structure Consistency Management
Sending letters in a world with faster-than-light travel? AI catches inconsistencies like that before they reach the page.

Frequently Asked Questions
Seosa's story bible system records technology levels, physical laws, and social structures, referencing them during episode generation to prevent setting inconsistencies.
Yes. The tone and vocabulary palette for each sub-genre are managed separately: neon/megacorp for cyberpunk, grand space for opera, oppressive regime for dystopia. Hybrid sub-genre settings can also be specified.
When new technology is registered, a card is generated across four axes: principles, limitations, costs, and social impact. When that technology appears in later chapters, the card is referenced to prevent overuse or contradictions.
Non-human characters have sensory input, decision-making logic, and emotional interpretation designed differently from humans. When they become POV narrators, the prose also reflects their mechanical or alien nature.
Yes. Setting hard SF prioritizes technical accuracy and numerical consistency; setting soft SF foregrounds social and philosophical issues and character drama.
