Copenhagen immediately puts you in difficulty: you have Nyhavn that you want to see at dawn, Tivoli Gardens that opens at 11, the National Museum that requires at least three hours, and in between, you have to figure out how to move among bicycles, metro, and canals. When I tried to build my itinerary on my own, I spent two evenings and the result was still chaotic. So I decided to test the three most discussed AI trip planners of 2026, bringing all three to the same city, with the same requests, to see who performed better in the field.
The test lasted five days in Copenhagen, in May 2026. I used Secret World AI Trip Planner, plus two other competitors that I will call Tool B and Tool C. I asked each the same questions: three days in the city, average budget (about €150 per day all included), interest in architecture, local cuisine, and some excursions outside the city. The results were very different from each other, and the winner surprised me with the quality of the details.
What I Asked Secret World and How It Responded
The first request was simple: “Build me a 3-day itinerary in Copenhagen starting from the Vesterbro neighborhood, prioritizing museums and local markets, avoiding peak hours”. Secret World responded in less than thirty seconds with a structured plan hour by hour. Day one started with a visit to the Glyptoteket at 9:30 AM (early opening, ticket 125 DKK), then walking to Strøget for lunch at the covered market of Torvehallerne, noting that the market is more crowded between 12 and 1:30 PM, so it recommended arriving at 11:45 AM. This level of practical detail impressed me immediately.
The second day included the National Museum of Denmark (free entry), with an estimated visit time of 2.5 hours for those focusing on the Viking sections, and in the afternoon a walk in the Frederiksberg neighborhood to the castle gardens. The AI had also calculated that from my accommodation in Vesterbro, the cycling distance was about 3.5 km, suggesting rental through Donkey Republic at about €4 per hour. I didn't expect it: no other tool had gone to this level of logistical granularity.
The Comparison with Competitors: Where They Make a Difference
Tool B, one of the most well-known on the market, produced a visually beautiful itinerary but full of generalities. It recommended Nyhavn "for sunset photos" without specifying that in May the sunset in Copenhagen occurs around 9:30 PM, which completely changes the planning for the late afternoon. It did not mention prices, did not distinguish between different opening days, and did not take into account the distance between attractions. I had to do all the cross-checking myself.
Tool C was more precise than Tool B, but it had a problem: the information on prices was stuck in 2024 and not updated. The ticket for Tivoli Gardens indicated was 120 DKK, while in 2026 it rose to 145 DKK for adults. A small difference, but symptomatic of an outdated database. Secret World, on the other hand, always specified the source and the date of the last price update, and in one case warned me that the cost of an activity was "subject to seasonal variations," inviting me to check on the official website. Honesty that I appreciate.
The Outing: The Test of Fire
I asked all three to suggest a half-day trip outside of Copenhagen. Secret World proposed Roskilde, 30 minutes by train (ticket about 90 DKK round trip with the Copenhagen Card), focusing on the Viking Ship Museum and the cathedral where the Danish kings are buried. They also pointed out that Wednesday mornings are less crowded at the museum and that the last useful train to return and have dinner in the city center leaves Roskilde at 17:42. This kind of operational information makes a difference when you are really traveling.
Tool B suggested Malmö, in Sweden, which is technically reachable in 35 minutes, but did not consider that it requires a passport for non-Europeans and a bridge fee of about 130 DKK. Tool C did not propose anything concrete, merely saying "consider an outing in the surroundings." In short, Secret World won this test without any discussion.
Final Vote: 9/10 — Here’s Why It’s Not a 10
Secret World AI Trip Planner deserves a 9 out of 10 for the quality of information, data updates, the ability to reason about real logistics and not just a list of things to see. In Copenhagen, it demonstrated a deep knowledge of the city: not just the main attractions, but the less crowded times, the real costs, the connections between neighborhoods. It is the most useful tool I have used to plan an urban trip.
The missing point for a perfect 10? The interface for modifying the itinerary in real-time is still a bit cumbersome: when I asked to move a two-hour visit, I had to rephrase the request three times before getting the correct result. A technical detail that will likely be resolved in future updates. But if you are planning a trip to Copenhagen — or any other European city — Secret World is the smartest starting point you can choose. Try the free version on Secret World and see for yourself how much of a difference it makes to have an assistant that truly knows the details.
