AI RPG Campaign Manager
Prep sessions faster with an AI co-author that knows your campaign.
Codex Cryptica combines a local-first campaign wiki with an integrated AI writing layer. Ask the Lore Oracle to draft an NPC for tonight's session, suggest a plot complication, or expand a location stub — all without leaving your notes and all stored privately on your device.
Core Capabilities
Lore Oracle AI
Context-aware AI that reads your existing campaign notes before generating new content, keeping everything consistent.
Local-First Privacy
All notes stay on your device. AI calls use your own API key or the shared proxy — nothing is stored on Codex servers.
Instant Vault Import
Generated NPCs, factions, and locations import directly as structured entities in your campaign vault.
