Novel Mage Feature
Codex (Lorebook)
Attach world-building that automatically grounds generations and chats.
The Codex is Novel Mage's world-building database a structured repository for every character, location, faction, artifact, magic system, historical event, and rule in your fictional world. Every entry you create in the Codex is automatically available as context for AI generation and chat, without requiring you to manually copy and paste it into each prompt.
Most writers already keep notes somewhere a Word document, a Notion page, a physical notebook. The Codex isn't just a cleaner place to store those notes. The distinction is that it's wired directly into Novel Mage's AI system. When you write a scene involving Elena Voss, the Codex entry for Elena Voss her physical description, backstory, motivations, relationships, speech patterns, and story role is automatically injected into the AI's context. The AI generating her dialogue knows who she is. It doesn't default to a generic character voice because you forgot to paste her profile into the prompt.
Codex entries have a flexible structure. You can use Novel Mage's built-in templates for character, location, faction, and item types, or create freeform entries with custom fields. Entries can link to each other Elena Voss's entry can reference the Ironhold faction she belongs to, which links to the city of Vael, which links to the political history of the Sundering. These relationships help the AI understand your world as a system, not as isolated facts.

How it works
Create entries in the Codex panel from any view in Novel Mage. Use a built-in template or write freeform. Add as much or as little detail as you have even a sparse entry is better than no entry for AI grounding. Link entries to each other using the relationship fields. When you write in a chapter that mentions a codex entity, Novel Mage detects the reference and loads the relevant entries into the AI context automatically. You can also manually pin specific codex entries to a chapter for precise control.
