In Stable Diffusion's sd-dynamic-prompts extension (A1111, ComfyUI, and others), a wildcard referenced as __color__ or __pose__ is backed by a plain text file — color.txt, pose.txt — placed in the extension's wildcards folder, one option per line. The more options you add, the more variety you get, but building a file per category, saving each one in a text editor, minding the encoding and trailing newline, and arranging them in the wildcards folder is tedious busywork. This tool assembles all those .txt files inside your browser and writes them out as a single ZIP. In the box on the left, write a header line like `color:` and list one option per line below it. Each header becomes its own __color__.txt (a wildcard named color); stack several categories and you get as many files as you need in one go (lines starting with # are treated as comments). Turn on 'Put in wildcards/ folder' and the ZIP is laid out with a wildcards folder so you can extract it straight into the extension. 'Remove duplicate lines' cleans up pasted options, and 'Sort lines A→Z' tidies each file. The right side previews the file names and line counts so you can check everything before saving. Files are written as UTF-8 with a single trailing newline, so sd-dynamic-prompts reads them as-is. When you instead want to see how a finished wildcard expands in a real generation, use wildcard-tester (this tool is for making the files; that one is for previewing the expansion). All processing happens on your device — your options and the generated files are never uploaded, stored, or sent anywhere.
