Imagina is an AI-powered RPG platform. You pick a world, choose a character, and play through a story where the AI narrates what happens based on your choices. It's not a chatbot: worlds have lore, characters, locations, and state that the engine tracks across your entire journey.
Worlds are the settings. They're authored by creators (or generated with AI) and contain everything the story needs: lore, NPCs, trackers, story beats, and instructions for how the AI should narrate. Browse published worlds to find one you like, or build your own.
Journeys are your playthroughs. When you start a world, you get a journey: your own instance of that world with its own history, state, and character. You can have multiple journeys in the same world, and they don't affect each other.
From there, type what your character does (or pick a suggestion) and the AI narrates what happens next. You can steer the story with the steering box, branch into alternate paths, undo turns, and switch models at any time.
Every account gets free credits: topped up each day just for showing up (with a bonus once you have logged in several days in a row), always spent first. After your free credits run out, turns draw from your Vault (the credits you buy, are gifted, or earn), priced by the model you picked and how complex the world is. You can buy credit packs or earn credits back by publishing worlds that other players enjoy. See the credit system for details.
