ShadeWindow: A Little Shade. A Better Walk

Description and use

ShadeWindow is a local AI walking planner that recommends shaded routes based on departure time, duration, and amenities, using solar geometry and a moving‑shade map.

Problem

Planning a walk that stays in shade while balancing departure time, duration, and amenities is cumbersome.

Outcome

ShadeWindow provides a lightweight local solution that recommends shaded walking routes, reducing reliance on cloud inference and enabling transparent, modifiable calculations.

Workflow

• Plan: enter duration, departure window, pace, shade/bench/rain preferences or describe them to the model.
• Compare: view three route options with departure times, moving‑shade maps, and score breakdowns.
• Save & go: save a walk card in the browser, reopen later, or print it.

Evidence

The moving‑shade map is the central idea: a route that looks appealing now may have a different shade pattern by the time you reach its later segments.
