If you want the sandbox to feel like a real book instead of a chat, Somni Tales is the closest alternative to AI Dungeon: you name a story, step in as the hero, and it opens as a living book — narrated aloud word by word, illustrated in ink, holding that world as canon, and building to a real ending. No subscription; 10 diamonds free to start.
The biggest differences from a freeform text adventure: your tale reads like a book (pages, drop caps, illustrations), every word is read aloud, it plays in 26 languages, and each story reaches an actual ending rather than drifting forever.
There's no subscription — you spend a few diamonds per choice, and built-in protection winds every tale to a real ending before it can run away with your wallet.

No card required. No subscription — diamonds from $5, spent only as you play.
