I had three days in Seoul and an impossible wish list: Gyeongbokgung Palace, Gwangjang Market, an evening in Hongdae, Jogyesa Temple, and at least half a day in Bukchon Hanok Village. Anyone who has visited the Korean capital knows that distances can be misleading: on the map, everything seems close, but between traffic, the subway, and mandatory stops, it's easy to lose track. It is in this context that I decided to test two different tools: Wanderlog, the most cited travel planner online, and Secret World AI Trip Planner, an artificial intelligence-based tool that promises personalized itineraries in just a few minutes.
I used both for six months, on different destinations, but the most rigorous test I did was on Seoul, because it is a city I know well enough to recognize when a suggestion is generic or truly useful. The result? A clear difference, which I will tell you about honestly.
What I asked the AI and what it answered
To Secret World I wrote exactly this: โThree days in Seoul, base in Myeong-dong, interest in traditional culture, street food, and nightlife. I want to avoid overly touristy places and understand how to move around with the T-money card.โ In less than forty seconds, the system generated a day-by-day itinerary with times, walking distances, and cost estimates. The first day started at Gyeongbokgung at 9:00 AM (entrance 3,000 won, about 2 euros), with the suggestion to rent a hanbok at the entrance to enter for free โ a detail that many sites do not mention. Then walking to Bukchon Hanok Village (12 minutes), stopping at Cafรฉ Yeonnam-dong 239-20 for brunch, and the afternoon at Jogyesa Temple, which is only 10 minutes from Anguk station on line 3.
In the evening, instead of sending me to Itaewon as 90% of standard itineraries do, the AI suggested Euljiro, the industrial neighborhood that has become the center of the local creative scene, with a selection of hidden bars in the alleys between the printing houses. This type of suggestion โ contextualized, not obvious โ is exactly what I expected from an intelligent tool.
Wanderlog: honesty above all
Wanderlog has its strengths: the interface is clean, the integrated map works well, and the import function from flight confirmation emails is really convenient. For pure logistics โ keeping flights, hotels, and bookings together โ it remains a solid tool. But when it comes to generating an itinerary for Seoul, the suggestions tend to be standard: Namsan Tower, Myeong-dong shopping, DMZ day trip. Nothing wrong with that, but nothing you wouldn't find on any blog from 2019.
The AI feature of Wanderlog, tested in the 2025-2026 version, responds generically to specific questions. To the same request I made to Secret World, it proposed an itinerary that did not take into account the base in Myeong-dong to optimize movements, placing Gwangjang Market (Jongno-5 area) on the first day and Hongdae on the second, without considering that the two neighborhoods are at opposite ends of the city and that traveling between them takes at least 45 minutes by subway. A mistake that an experienced traveler notices immediately.
Seoul day by day: how Secret World optimized the routes
The most concrete added value was in the logistics of transfers. Secret World grouped attractions by geographical area: the entire historic center (Gyeongbokgung, Changdeokgung, Bukchon) on the first day, the Gangnam area and Coex Mall on the second afternoon after a morning in Insadong, and the third day entirely dedicated to the western part โ Hongdae, Yeonnam-dong, and the Gyeongui Line Forest Park, a 6 km green strip that connects the two neighborhoods on foot. No unnecessary jumps from one side of the city to the other.
It also included practical details that make a difference: Gwangjang market opens at 8:30 and bindaetteok (mung bean pancakes) cost about 4,000 won per serving; the AREX airport line from Incheon to Seoul Station takes 43 minutes and costs 9,500 won; the combined ticket for the five royal palaces costs 10,000 won. Small information, but concrete, verifiable, useful.
The final vote: 9/10 and why it is not 10
Secret World AI Trip Planner deserves a 9 out of 10. The missing point is for the customization of dietary preferences: I specified that I do not eat seafood, but on a couple of occasions the suggested restaurants specialized in haemul pajeon or jjampong. Nothing serious, but in a city like Seoul where food is central to the travel experience, greater accuracy is expected. For everything else โ quality of suggestions, optimization of movements, practical details, and the ability to go beyond tourist clichรฉs โ the tool exceeded expectations and, above all, surpassed Wanderlog on almost all fronts that really matter.
