github/gitignore ? reverse-engineered prompt

I need a tool to help me generate .gitignore files for my projects. I always forget what to add. It should be based on the official GitHub collection of gitignore templates. I want to be able to specify the technologies I'm using, for example 'Python', 'Django', and 'VSCode', and have it generate a single, combined .gitignore file for me. It should be smart enough to pull the main template for the language or framework and also grab the right ones for my editor and operating system from their 'Global' folder. Basically, I want to type in my tech stack and get a comprehensive ignore file that I can just save to my project, without having to manually hunt down and combine multiple template files.
