FAQ

Frequently asked questions

Is there multiplayer?
Yes — real-time cooperative sessions for up to 4 players (Hero) or 6 (Guild), synced live. The Wanderer (free) plan is solo-only.
Which AI powers the Game Master?
Google Gemini or 100+ OpenRouter models, or a fully self-hosted local model via Ollama, LM Studio, vLLM, or LocalAI — your choice, per plan.
Are my API keys and payments secure?
Bring-your-own API keys are encrypted at rest with AES-256-GCM. Payments are processed via NOWPayments (crypto), verified through signed webhooks.
Can I export or delete my data?
Yes — export your full profile, campaigns, and stats as JSON, or delete your account entirely, any time.
How does the AI remember a long campaign?
A six-layer memory system — rolling recent messages, compressed chapter summaries, a long-term story arc, and never-compressed key events — plus semantic recall of older moments via pgvector, built specifically to reduce continuity errors in long sessions.
