"generated by artificial intelligence tools"* is a broad description. The "learn more"/AI policy page of Stackoverflow also talks of
any answer crafted in part or in whole using a tool that writes a response automatically based on a prompt it is provided
So when we take this literally, this would effectively make it impossible to use contemporary translation services or grammar checkers for assistance, since those are AI tools as well which write a response automatically based on a prompt.
However, this SO Q&A gives me the impression that translation tools are not prohibited, at least not when they are specialized on translations which preserve the original meaning. Moreover, the formerly mentioned AI policy page only contains examples in terms of LLM based services, and not translation tools or grammar checkers. That leaves anyone like me - who is not an English native speaker and uses a translation service from time to time - in a very unsatisfying state of uncertainty if that is still ok or not.
I understand the desire not to restrict the AI ban to LLMs alone, since we do not know what new fancy kind of AI tool will hit the market next month, and if the term LLM will still fit to them, but when certain AI tools like translations service are allowed (maybe under certain restrictions), IMHO the AI policy pages should be clearer about that. And when translation services are prohibited in general since they all fall into a broad interpretion of "generative AI", then the policy should state that.
