"Doko Demo Lokehan" Dev Used Claude Max To Build Every Manga Tool
The tool drew a wave of new manga-assist apps in its wake, and its OpenStreetMap credit question directly produced the follow-up tool "World Gacha," which generates fictional streets with no credit requirement.

The developer behind manga background tool "Doko Demo Lokehan," published under the handle ++++ (Sharp), had almost no programming experience before building it. The browser tool recreates real streets in 3D from place names or coordinates, free and without registration, and is built on Claude Max's 20x plan rather than image generation AI. Street data comes from OpenStreetMap, not Google Maps, which requires the credit "© OpenStreetMap contributors" when backgrounds are used.
The map data question shaped the tool that came after. Users asked whether backgrounds made in "Doko Demo Lokehan" could be used commercially under the map license, and the volume of those questions led the developer to build a second tool that avoids licensed map data entirely.
"World Gacha" generates fictional streets, from castle towns to hillside districts to a city of water above a waterfall, and needs no credit line at all. Camera placement can be adjusted to work out a composition. The developer describes the current pace of manga-assist tool releases as a "Warring States period."
