Claude vs ChatGPT vs Gemini as a Dungeon Master
Claude, ChatGPT, and Gemini are all capable enough to run a tabletop RPG — the deciding question is not which model narrates best, but whether it is connected to a rules engine. All three are creative, patient narrators; none of them, on its own, rolls real dice or keeps an honest ledger. The model you pick matters less than whether the numbers are enforced.
How do the three compare for RPGs?
| Model | As a narrator | Custom-tool (MCP) connector support |
|---|---|---|
| Claude | Strong, consistent long-form roleplay and character voice | Smoothest custom-connector support today (desktop and web) |
| ChatGPT | Strong and widely used, large ecosystem | Custom-connector support rolling out |
| Gemini | Strong, with long context useful for lore | Custom-connector support rolling out |
Connector support changes quickly — check each app's current docs. The point below holds whichever you choose.
Why the model isn't the deciding factor
Every one of these models shares the same weakness as a DM: it generates plausible text, so over a long game it drifts — heals too much, re-rolls a failure into a success, loses track of gold. That isn't a quality gap between models; it is what language models are. The fix is the same for all three: pair the AI with a deterministic engine that owns the dice and the sheet.

So which one should I use?
Use whichever you already pay for. lorewend is a connector, not a separate AI — it runs inside Claude, ChatGPT, or Gemini and gives any of them real dice, tracked HP and gold, and a living world. Today the setup is smoothest on Claude; ChatGPT and Gemini work as their connector support matures. Either way you keep your subscription and add honest rules on top.
Try it with your AI
The setup guide covers connecting each app, and the companion screen shows the dice and character sheet straight from the engine — so you can judge any model's storytelling while trusting the math underneath.
Frequently asked
- Which AI is the best Dungeon Master?
- All three major models — Claude, ChatGPT, and Gemini — narrate well enough to run a great game, and none rolls real dice on its own. The best results come from whichever you already use, connected to a rules engine that enforces the numbers.
- Can I use the same game on Claude, ChatGPT, and Gemini?
- Yes. Because lorewend is a standard MCP connector, the same campaign and engine work in any AI app that supports custom connectors — your game state lives on the server, so it is shared across the apps you connect.
