A detailed explanation of the three AI GM personas that guide your adventures in this app and how to choose the right one for your playstyle.

What is AI GM?

In this app, an AI (Artificial Intelligence) serves as the Game Master. While traditional TRPGs require a human GM, with an AI GM you can play solo anytime, 24/7.

How AI GM Works (Technical Explanation)

How Does It Function?

AI GM uses the Google Gemini API.

  1. Your input → System analyzes
  2. GM persona rules applied
  3. Scenario settings considered
  4. Natural dialogue generated
  5. Images generated when needed

Does It Learn?

Current AI GM does not learn from your play.

This means:

  • ✅ Privacy is protected
  • ✅ Always a fresh experience
  • ❌ Doesn't remember previous sessions

Future implementation of in-session memory (remembers within same game) is planned.

Frequently Asked Questions

Q: Which GM is the strongest?

A: They are equally strong. The difference is only in "voice" and "atmosphere." Difficulty is determined by the scenario.

Q: Does the story change with different GMs?

A: Yes, it changes significantly. Even with the same scenario, developments and descriptions differ based on GM personality.

Q: Does AI make mistakes?

A: Occasionally. If something seems clearly wrong, point it out in chat. The AI will correct it.

Q: What if the GM makes an unreasonable judgment?

A: Ask for the reason. Type "Why did you make that judgment?" and the AI will explain.
