What makes Codex Cryptica different from other RPG campaign managers?

Codex Cryptica is fully local-first: your notes are stored on your own device, not a remote server. That means instant load times, complete privacy, and full offline support — features most cloud-based campaign managers can't offer.

Can I use Codex Cryptica offline?

Yes. Codex Cryptica operates fully offline by storing files locally on your device. Codex Cryptica's local-first markdown capabilities, interactive relationship graph, and campaign manager run entirely in the browser without requiring an internet connection.
