Novelcrafter is a specialised writing platform built to support the complete novel-writing process. Its central feature, Codex, allows writers to organise characters, locations, objects, relationships, and worldbuilding information in a structured database. Writers can use AI to generate scenes, summarise chapters, extract character information, and brainstorm ideas. Unlike platforms that provide their own bundled AI generation credits, Novelcrafter uses a Bring Your Own Key system, allowing users to connect supported AI providers and pay for model usage separately. It is particularly suitable for authors working on long novels or interconnected book series
