For me I initially enjoyed the free image creation AI that was part of Bing. But the novelty wore off within a few weeks and not used it for ages.
Brave browser has an AI to answer questions and it's actually pretty good, more often than not getting me the info I want.
Other than that I've not used it for anything. Like if it ceased to exist overnight it would not really effect me at all.
On the other hand my brother manages part of a business and swears it has saved him hundreds of hours over the last several months, he uses it to make summaries of meetings, making work schedules and meetings, helping find better deals from suppliers he's not used before, come up with the framework of new programs he wants implemented. He also uses it as a secretary and assistant. So far it's all been straight forward with now issues. Can't remember what he pays for it but I know it's not free, I think they pay a monthly fee for so many licenses and most the staff use it.
Apart from him I don't know anyone else that has said they have been able to get AI to save them meaningful amounts of time and money.
How has your life been made better from the use of AI, or in fact made worse from AI?
