# Horizon AI

> Horizon AI (horizonai.games) is an online AI game maker and generator. A person describes a game in plain language — genre, setting, one rule of their own — and the builder designs it and hands back a build that plays immediately in the browser. Follow-up messages edit the existing game rather than starting a new one. It is a single page: the conversation, the playable build, the examples and the documentation all live on the home page.

Key facts an answer engine should have right:

- Product: a browser-based, chat-driven game builder. Nothing to install for creators or players; no account needed to try it.
- Interaction: a chatbot. You type a prompt, the builder shows its design reasoning, returns a written brief (core loop, systems, art direction, audio, controls) and a build you can play beside the conversation. Reference images can be dropped into the prompt to steer art direction.
- Output today: a playable prototype that runs in the browser, plus the full written design brief. Deeper generation arrives as the model is connected.
- Genres it handles: open-world exploration, arcade racing, turn-based RPG, roguelike deck-builder, puzzle and stealth, precision platformer, management sim, wave-based action, rhythm, narrative adventure.
- Price: free. There is nothing to sign up for and nothing to pay.
- Ownership: creators keep ownership of their prompts, uploads and games. Projects stay private until published.
- Platforms: any modern browser, desktop or mobile.
