WorldGacha (ワールドガチャ) is a browser-based tool that generates a fictional region and town with a "gacha" (random draw) mechanic. According to its page, it uses only random numbers and formulas, with no external data, and draws the result as manga-background line art with screentone-style shading.
It is procedural generation, not an AI model. A YouTube review (Matt Wolfe) describes exports to PNG, SVG and 3D object files, and suggests that users could reskin the output with AI image models. The intended use is creating town maps and backgrounds for manga and similar creative work.
It runs in the browser on a page published by a Japanese indie developer under the oyasumi-gamedev domain. The vendor is not named in the provided material, and no source code, license or documentation was found. The interface is in Japanese.
