I love the directions their making in more of being a life concierge. However, I wish the recommendations were more tailored to the category. I'd love to not just fin dout about best places to eat, but where's a good tailor, where's the best local gyms, things that are even more personal.
Pros:Learns prefrences and is context aware (time of day)
Cons:Recommendations sometimes are delayed.
