Platform overview
How omorashi.ai games work — the kinds of games you can build, how the engine runs your code, and where to look next.
omorashi.ai lets you build interactive, AI-driven games and stories and play them in the browser. You describe what you want, the coding agent writes the game, and the engine runs it on our infrastructure — no servers to manage, no model APIs to wire up.
What you can build
- Characters and companions — one-on-one chat with an AI character who has a real personality and remembers you.
- Casts that think for themselves — scenes and dramas where every character has its own goals and private knowledge, not one narrator playing puppets.
- Text-based RPGs and adventures — quests, missions, and branching stories, with scene art generated as you play.
- Illustrated interactive stories — narrative dramas with consistent character portraits and on-the-fly illustration.
- Mysteries you can genuinely solve — a fresh, internally consistent mystery authored each playthrough, with suspects who lie for their own reasons.
- Tabletop-style play — turn-based games with dice, cards, hidden information, AI rivals, and AI judges.
- Games that live in real time — pets, people, and worlds with needs, moods, and growth that keep evolving while you're away (see
background-play). - Physiological simulation — tick-driven body models (bladder, hydration, sleep, desperation) that drive how characters feel and behave, from a single held-too-long scenario to a fully autonomous life sim.
Games here are turn-based and low-graphics by design — the engine isn't built for real-time action, physics, or 3D. how-games-work covers what fits and what doesn't.
How it runs
Each game is a small TypeScript project. You define agents (LLM-backed characters), state (what persists between turns), and event handlers (what happens when the player acts). The engine handles model calls, state snapshots, and rendering the chat UI.
