I used Muse, Instinct, and Grok Bot to plan my European vacation. Meta's AI agent was my favorite.

This as-told-to essay is based on a conversation with Jay Eskenazi. He lives in Los Angeles and worked in user experience for 19 years. It's been edited for length and clarity.

I'm in Paris, and I'm going to Barcelona tomorrow. The trip is three weeks.

I came here for the first time last year, and it was my first long trip by myself. Last year, planning it was very stressful, and I did a ton of research.

This year was the same thing, where I had these very long notes. At this point, everyone knows that you can go to any AI tool and say: "Hey, I'm going to City X, give me an itinerary for seven days."

I had this epiphany a few weeks ago, where I realized I had all these note files, bulleted stuff, and coffee shops to go to.

If someone gave you a list of five coffee shops and they were in five different cities, as someone who's not familiar with the terrain, you wouldn't necessarily know how to structure that in the course of the day. Which coffee shop goes with which museum?

So, instead of doing an itinerary, I was like: "Here's my notes. Put them together in an organized way for me. Structure them in a logical sequence."

I hadn't used Claude in a while, so I tried that a little. I use Grok a lot, and I just upgraded because I wanted to play with the Grok Bot. So, I made this really fancy itinerary. I kept iterating it. It did a really good job. Then I got here and was like, "It's not as good."
