WebNovelAI is a structured web fiction writing tool guiding authors from concept to manuscript. It has an 8-step planning process (Story Concept, World Building, etc.) for narrative consistency, plus genre-specific templates (LitRPG, Progression Fantasy) and style presets (Grimdark, Cozy Fantasy) matching platform rules. Users create detailed character sheets with RPG stats, design world rules and map character relationships—AI references these in drafting—and it allows custom chapter length (2000-4000 words), perspective and style, exports in TXT/MD, supports multiple projects, suiting new/experienced authors for platforms like Royal Road.
