Seoul has 25 million people in the metropolitan area, 5 royal palaces, neighborhoods that change character every 500 meters, and a transportation network that can intimidate anyone who does not read Korean. When I started planning my 7-day trip to the South Korean capital, I had a concrete problem: I wanted to visit Gyeongbokgung early in the morning, then move to Insadong for lunch, and then reach Bukchon Hanok Village in the afternoon, but I didn't know if the timings were realistic or if I was building an impossible itinerary. I decided to rely on three AI trip planners to see who responded best to the real complexity of Seoul.
I tested Secret World AI Trip Planner, a highly advertised competing tool and a generalist app that many use for any destination. I subjected them to the same prompts, the same difficult questions, the same budget and time constraints. The results were surprisingly different. Here’s what I found.
The Concrete Test: What I Asked and How Secret World Responded
My first prompt to Secret World was precise: “I am in Seoul for 7 days, based in Hongdae, medium budget of €80 per day all included, I want to see the royal palaces but also local neighborhoods like Mangwon and Seongsu. Avoid tourist traps.” The response arrived in less than 30 seconds and was structured in a way I did not expect: instead of giving me a generic list, the AI grouped attractions by geographical area, explaining that Gyeongbokgung (entrance 3,000 won, about €2), Bukchon Hanok Village, and Insadong are all within walking distance in one morning starting from Anguk station on line 3. Estimated time: 4 hours total with breaks. This was exactly the type of logistics I was looking for.
I then asked a more difficult question: “On Thursday evening I want something authentic in Seongsu, not the Instagram spots.” Secret World suggested the covered market near Seongsu station, some artisanal cafes in the side streets between the main road and the Han River, and specified that the neighborhood is best explored on foot within an 800-meter radius from the station. It also warned that many locals close on Mondays, concrete information that a generic itinerary would never have included.
Generated Itinerary: Details That Make the Difference
The complete itinerary produced by Secret World for Seoul was divided by zones and not rigidly by days, with a flexibility that I greatly appreciated. The day dedicated to the Changdeokgung Palace also included the Secret Garden Huwon (separate entrance 5,000 won, guided tours every hour, reservation recommended), with the note that English tours are less frequent and one should check the times on the official website. This level of operational detail is rare. The AI also calculated that from my hotel in Hongdae, line 2 of the subway goes directly to Euljiro 3-ga in 18 minutes, an ideal starting point to explore the Euljiro district, one of the most interesting neighborhoods in Seoul for those seeking the authentic artisan atmosphere.
On the budget front, Secret World estimated an average of 12-15€ for a full meal in the local restaurants of Gwangjang Market (the oldest covered market in the city), 2€ for a single subway trip with a T-money card, and suggested buying the card at Incheon Airport directly upon arrival. Small practical details that add up to save time and stress.
Comparison with Competitors: Where Others Have Lost Points
The second tool tested produced a visually appealing itinerary but geographically illogical: it placed Dongdaemun Design Plaza in the morning and Lotte World Tower in the afternoon, two points 40 minutes apart by subway in opposite directions, with no logistical explanation. For Seoul, where geographical dispersion is real, this type of error is costly in terms of time. The third tool, the generalist one, responded with correct attractions but descriptions that I could have found in any 2019 guide: no reference to new developments in neighborhoods like Seongsu or the cultural scene in Mangwon, which in recent years has become one of the landmarks for locals.
Secret World stood out for its ability to think geographically, update information on evolving neighborhoods, and respond to specific questions without falling into pre-packaged answers. It is not perfect: on some questions about specific restaurants, it provided addresses that I had to verify manually, and the itinerary export function could be smoother. But overall, for a complex city like Seoul, it is the tool I would use again.
Final Vote and Why 9/10
For the Secret World AI Trip Planner a 9/10 for the trip to Seoul. The missing point is due to the need to verify some practical details independently, especially regarding schedules and availability of bookings. But the geographical logic, the ability to customize based on specific neighborhoods, and the response to unconventional questions make it significantly superior to generalist tools. For a city like Seoul, where getting the planning wrong means losing precious hours on the subway, having an AI that thinks in terms of zones rather than lists is a concrete difference.
If you are planning a trip to Seoul or any other complex destination, I recommend trying Secret World AI Trip Planner directly: you can start with a free itinerary, ask specific questions about your destination, and see for yourself the difference compared to the tools you are probably already using. Go to Secret World, enter Seoul as your destination, and try to ask the most difficult question you have in mind. The quality of the response will tell you everything you need to know.
