DocSmith

DocSmith is a game design document tool for game developers: structured GDD sections with guided prompts, a living dependency map that shows what breaks when you cut a feature, honest scope-vs-budget math, one-page pitch export, and versioned change logs. 100% offline.

Write your GDD across 7 guided sections (pillars, core loop, systems, content plan, art, audio, scope/budget), list features with size/risk estimates, and click any feature on the living dependency map to simulate cutting it — impacted features turn red. The scope-vs-budget verdict meter does honest person-day math, and the built-in sample GDD (HOLLOW DEPTHS) shows the format in action.

The free demo includes the GDD editor with demo limits (3 sections, 5 features, exports disabled).

The full DocSmith Pro ($9.99 one-time): https://theluckyduck666.itch.io/docsmith-pro — all 7 sections, unlimited features, and all exports (one-page pitch, Markdown, printable HTML).
