Solves the actual hard part of custom icons: making 20 of them look like they belong together. You tell it the project (say, a plumbing site), it suggests relevant icons grouped by purpose (navigation, trust signals, industry-specific), then generates a complete SVG set with enforced consistency. Same stroke width, same corner treatment, same visual density across every file. It even does optical corrections so a simple chevron doesn't look weirdly lightweight next to a complex gear icon. Ships with a preview HTML file and style spec JSON. Way faster than drawing icons individually in Figma and way more distinctive than dropping in Heroicons for the thousandth time.
