Dunia

Dunia is an AI interactive-fiction platform: describe the world you want — a fantasy kingdom, a sci-fi station, a noir city — and the AI builds characters, locations, lore and plot hooks; then you create your character and step in as the hero. The AI narrates and plays every other character, generating dialogue, twists and scenes in real time from your choices; characters stay consistent across long stories and the narrative remembers what happened. You can edit any message, branch the plot or undo a choice so the story goes exactly where you want. It ships a one-click Creation Wizard and an inline Editing Assistant for worldbuilding, supports solo and multiplayer play (invite friends as distinct characters in one world), and lets you publish worlds for others. The free tier gives 75 credits/day; paid plans at $19.95/$39.95 per month scale daily credits, with one-time credit packs.
