# Compare Countries by Metrics

Making informed decisions about international expansion, investment, or policy requires comparing countries across multiple dimensions. GDP, population, area, literacy rates, and other indicators each tell part of the story, but the real insight comes from seeing them side by side.

The compare skill provides structured side-by-side comparisons across all available metrics, making it easy to spot differences and similarities. Instead of looking up each country separately and manually comparing, you get a clean comparison that highlights where countries diverge and where they align.
