Project details
Writing tools generate paragraphs. Your users need complete, coherent books chapter by chapter, in their voice, at scale.
This is a production-ready AI SaaS web application that turns a prompt into a full multi-chapter book. Users define genre, tone, characters, and structure the platform generates consistent output using OpenAI API, with a context management system that keeps the story coherent across 20+ chapters.
Built on NestJS, React.js, PostgreSQL, and a structured prompt engineering layer not a wrapper around ChatGPT, but a purpose-built AI content platform.
What your platform delivers:
Multi-chapter generation with narrative continuity across the full book
Genre, tone, character, and chapter structure customisation per project
Multi-project workspace users run several books simultaneously
Iterative editing refine any chapter without regenerating the whole book
Export pipeline structured, download-ready output
Under 8 seconds per chapter generation in production
Custom options: additional AI models, Stripe billing, or white-label branding.
