AI Dungeon vs GPT Games

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors. AI Dungeon publishes a starting price ($14.99); GPT Games does not. Both have a free tier.

What our research says

AI Dungeon

Still the deepest AI text-adventure product there is, with seven years of scenario library behind it, and the only one where memory and world-state tooling is the actual product. It is entertainment, not a writing assistant — do not buy it expecting to finish a manuscript.

Pros

  • Memory, world info and scenario tooling are far more developed than in general chatbots used for roleplay
  • Multiple model choices per tier, including newer models added through 2026
  • Native iOS and Android apps, not just a mobile web wrapper
  • Large public scenario library gives an immediate starting point

Cons

  • Five-tier ladder from $14.99 to $99.99 is steep, and context length is the thing being sold at every rung
  • Credits do double duty for images and for extra context, so heavy sessions drain them quickly
  • No API, so scenarios cannot be driven from outside the platform
  • The service has changed content and moderation policy sharply in the past, which still colours community trust

GPT Games

A pleasant five-minute distraction: pick a community-written game and play it as a conversation, or write one yourself in a prompt. It is a hobby project with no account, no billing and no sign of active development, so treat it as a curiosity rather than a platform.

Pros

  • Playable immediately with no signup or payment
  • Anyone can publish a game defined purely by a prompt
  • Game list is public, so there is something to play on arrival
  • Explicit disclaimer that the model can be wrong about facts

Cons

  • Still labelled beta with no visible development activity
  • No accounts, saves or progress tracking
  • Nothing but a chat interface — no images, audio or state beyond the conversation

Which one fits

  • Anyone curious how far a story engine can go without authored branches

Choose GPT Games if you need

  • Trying prompt-driven text games without signing up
  • Sharing a one-off game idea as a link
