That there is a no-ai tag is a very good idea.
Some thoughts and questions about this new feature.
Will the sub tags have negated tags as well? I guess, most users would want to use this functionality to not see AI projects. So, like browsing for no-ai-text + no-ai-images + no-ai-sounds to not exclude all the games that used llm to generate a basis for some of their code.
The AI debate mainly focuses on anything that is called art. It is most important to disclose it for assets, since they in turn would make the projects that use them be AI using projects. But funnily enough, code does not seem to be considered much in those debates. Coders also typically do not call themselves artists. But AI usage seems to be rampant in modern software development.
Also there is certain filtering and editing options in the big graphic editing softwares that use AI tech. So from a purist's view, usage of Adobe Photoshop would constitute usage of generative AI content tool. They even have functions that have generative in their title, like generative fill that works with a prompt.
So maybe some clarification would be in order in the faq. There are people that take words literally, and if you cite music and they used ai-voices, they might think to be exempt - maybe they even are, since an AI voice does not use a prompt. And if you cite the major llm products and they "only used Photoshop" they might also not grasp that using a prompt to do something is generative AI usage, no matter how it is called in your editing tool. And there are functions that do not use a prompt, yet generate content - generative expand at least has generative in its name.
In other words, make the wording as non ambigous as you can, so even people with little or no knowledge English that see an AI translated version will understand . You might avoid some people asking support, if their thingy is considered AI or not.
Oh, and will we see the AI meta info in the information box? Currently there is no information. Only assets/games, that have this as an actual tag, have it displayed.
