This AI thing, what are you using Gemini to achieve, that the OS doesn’t do natively?
There are AI features on iPhone such as Maui sort and rewriting but I don’t find them to be relevant to my needs. Occasionally I use ChatGPT, once every 14 days maybe, to answer a question or provide a framework.
Xcode has ChatGPT in for coding help which is very useful for work.
If you have to ask the question then AI isn't something that most likely moves the needle for you. For a lot of us, we see AI as the future and I personally am continually amazed daily by the things that it can do and how incredibly useful it is in all aspects of my daily life.
