AI-Assisted Game Mastering

AI DM Assistant for Tabletop GMs

Draft, revise, and expand your campaign lore with a built-in AI co-author.

Codex Cryptica includes an AI-assisted writing layer called the Lore Oracle. It reads your campaign context, answers questions about your world, helps you draft NPC descriptions and faction goals, and suggests revisions to existing entries — all running locally with your own API key.

Core Capabilities

Context-Aware Lore Oracle

The AI reads your existing campaign entities and drafts new content that fits your established world.

Inline Revision Suggestions

Select any text in your notes and ask the Oracle to expand, condense, or rewrite it in your campaign's voice.

Bring Your Own API Key

Connect your Gemini or OpenAI key for full AI generation — no subscription or data sent to Codex servers.
