I think we should have an AI tag, and "not AI" should be the default (otherwise we add "non-" versions of every tag and post titles are a list of what something isn't instead of what it is).
Imo, a lot of the tools here have a high security requirement. Either because they handle personal/private information and/or are exposed to the public internet. AI use is a red flag to me that the developer hasn't properly considered all the security implications of their product.
