I've been using AI a lot for work. Part of my job is writing out what I guess could be compared to instructions. People will hang of every syllable so it needs to be correct and easy to read. So I write it up and then basically tell it to "correct grammar and improve flow". Works great. Sometimes it spits out damn near what I write which tells me I'm doing ok.
Recently used it to help me decide how to mix my 401 and I thought it was pretty dead on and it had two funds I'd already chosen.
