One of the only “AI” features that I’ve ever actually found useful was the thing that warned me when I sent an email that was missing an attachment. Basically, it was able to deduce that an attachment was likely missing, and showed me a “are you sure you want to send” prompt.





That is true. You can have check for certain words and phrases that’s hardcoded in. However, I have reason to believe the feature I experienced was using an LLM rather than a hardcoded list of search patterns.
