MDL Documentation

What MDL does

You write creative direction — a setting, a cast, rules for how the world works — and MDL turns it into a playable game. Players type what they want to do, and the AI generates narration, dialogue, scene changes, music cues, and character expressions. Every playthrough is unique.

What you provide

• Instructions — the full instruction files that shape your game's story, characters, tone, and generated media.
• Schema — the visible runtime contract for the game's structured output.
• Assets — character sprites, background art, music tracks, and sound effects.
• Title screen — your game's branding, logo, tagline, and intro message.

What MDL provides

• Runtime engine — handles player input, AI generation, state management, and bounded prompt history.
• Workspace — tools to manage your game's configuration, assets, and prompt.
• Hosting — serve your game to players, optionally on your own domain.
• Monitoring — track usage costs, generations, players, universes, and purchases.
• Earnings — a visible coming-soon surface for future creator revenue share and payouts.

The player experience

Players see a visual novel interface: backgrounds, character sprites, dialogue, and a text input. They type what they want to do or say, and the story continues. Each player's universe (save file) tracks their unique path through the story. Saves persist automatically.
