What is an AI story game?

It is a game where an AI writes the story as you play. Some, like AI Dungeon and FableAI, let you type what your character does. Others, like Plot Twister, let you steer characters with whispers and events. The AI writes what happens next.

Which AI story games are free to try?

As of October 2026, AI Dungeon's site calls it free, FableAI's site lists a forever-free plan, Hidden Door's pricing page lists a free plan, and Friends & Fables lists a free tier with a daily turn limit.

Are there AI story games for iPhone?

Yes. AI Dungeon, FableAI, Everweave and Plot Twister all have US App Store listings. Hidden Door's site did not name platforms, and NovelAI's site says it works from a mobile device with no installation.

Are AI story games suitable for children?

Check each one. On the US App Store, AI Dungeon, FableAI and Everweave are listed 13+, and Plot Twister is listed 16+. Plot Twister's episodes carry content warnings, and its stories are labeled AI-generated.

Is Plot Twister like AI Dungeon?

Only partly. Both use AI to write what happens next, but in Plot Twister you are not the hero and you do not type your own actions. You whisper thoughts into characters' heads or inject events, in pixel-art episodes you can rewind and branch.

Best AI story games

Updated October 2026 · By Reno Labs

For an open-ended AI text adventure where you are the hero, start with AI Dungeon or FableAI. For tabletop-style rules and a party, try Friends & Fables. For a narrator-led world, try Hidden Door. For steering characters through short pixel-art episodes, try Plot Twister, which we make. For writing with an AI, try NovelAI.

Disclosure. We make Plot Twister, and it is in this list. We tried to rank it fairly: by fit, it comes sixth of seven, because it is a different kind of game from an open-ended text adventure. Facts about other products come from their websites and US App Store listings, read in October 2026.

How we chose

We included AI story and text-adventure products that are live, with an official site or App Store listing we could read. We ranked them by how closely each matches an open-ended AI text adventure, since that is what the search "AI text adventure" describes. That is a ranking by fit, not by quality. Each entry has a "best for" line so you can skip the order. We left out any product we could not verify, including Perchance, whose pages refused our request, and Infinite Worlds, whose site showed an error. Price models are quoted as shown.
