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

In a first-person “as-told-to” essay, Jay Eskenazi describes planning a three-week European trip from Paris, moving to Barcelona the next day. He says he used multiple AI tools to turn long notes into a workable schedule rather than a simple day-by-day itinerary. After updating and trying Grok Bot, he found the plan looked good in the interface but felt less effective once he arrived. Muse, which he used briefly before leaving, produced an afternoon itinerary with new details and handled real-world constraints—like museum closures and which days are free—more like a structured decision process than a basic list. The standout capability, he says, was mapping stops with pins and exporting routes to Google Maps. Eskenazi also timed the trip around an annual festival, though core events weren’t fully published.
