An AI Dungeon alternative with rules, goals and endings
AI story games like AI Dungeon let a language model make up the world as you play. That is great for open-ended storytelling, and frustrating when you want a game: the rules bend, the map shifts and nothing is ever really at stake. Games in Chat is built the other way round.
How it's different
| AI story sandboxes | Games in Chat |
|---|
| Who decides what happens | The AI model, as it writes | A game engine; the AI only narrates |
|---|
| The world | Generated as you go, so it can shift | Written down before you start: places, people, items |
|---|
| Goals and endings | Open-ended; the story goes on | Every adventure has a goal you can win or lose |
|---|
| Secrets | The AI invents them, so it can change or reveal them | Sealed on our server; the AI never sees a mystery's solution |
|---|
| Dice | Whatever the story needs | Fair d20 rolls made by the engine |
|---|
| Content | Varies by platform and settings | Written for ages 13 and up |
|---|
| Where you play | The platform's own app or site | On the web, or inside Claude and ChatGPT |
|---|

When a story sandbox is the better choice
If you want to wander anywhere, invent your own world on the fly or co-write an endless story, an open-ended AI storyteller is the right tool, and Games in Chat isn't trying to be one. Our adventures are finite: a map, a cast, a goal, and an ending you earn. If you like that shape but want your own story, you can write an adventure and the engine will run it.
Is it free?
The Daily Mystery and three adventures are free, on the web and inside Claude and ChatGPT, with no account. Plus ($5 a month) adds the rest and every past daily case.
Can I play it inside ChatGPT or Claude?
Yes: add Games in Chat once and your chat's own AI becomes the narrator, while our engine keeps the rules. See how to play an RPG with ChatGPT or Claude.
