Do I need an AI subscription to use this?

No. You can use the shared system proxy for free, or bring your own Gemini or OpenAI API key for unlimited usage. Codex never charges for AI usage.

Can the AI see all my campaign notes?

Only what you share with it. The Oracle reads selected entities you explicitly include in a prompt — nothing is sent automatically.

Does it work offline?

The campaign wiki and graph work fully offline. AI generation requires an internet connection to reach your API provider.

AI-Powered Campaign Management

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.
