I mean I just used muse to plan out my entire weekend trip to Vegas recently. I booked everything myself but I asked it to shortlist dining options for me given dietary restrictions, events given restrictions (with elderly family), etc. it basically handled all the stuff I would have normally just Google searched for. Plus it made a nice web app dashboard to display it all. It seems pretty useful for common use.
It also handled payment splitting. I told it what person x spent for the group split 3 ways (it originally split by the total number of people, but I clarified that only me + x + y are paying) and it kept running totals. When I got an email from Venmo saying x sent me money, muse automatically updated the balance sheet.
We saw some signs written in an unfamiliar language. Muse told me what language it was.
Is that your first time using an LLM? I don't mean that in a snarky way, it just seems like things everything could do for years.
I think some of those tasks are part of the fun of a trip - doing the research on locations, events, restaurants, etc. You stumble through a bunch of things and little nuggets of that sit in your brain and then when you're on the trip they might come up - one place is abruptly closed, something looks like a bummer in person, etc. Without doing that research yourself then on the trip you have a list of things and aren't really knowledgable about alternatives.
Like I said, I'm not the target audience for a personal assistant. That does sound like a more ideal UX than what chat gippity and the others offer though. I would expect that with Meta - they really get the UX mostly right for people.
