I had three days in Berlin, an endless list of places to see and zero desire to spend hours on Google Maps figuring out how to connect Checkpoint Charlie with the Jewish Museum, Prenzlauer Berg, and the East Side Gallery without going crazy between the U-Bahn and trams. It was at that moment that I decided to seriously test Secret World AI Trip Planner, a tool that promises to do exactly this: build smart itineraries based on real preferences, not on lists copied from other blogs.

I used Secret World for the first time in January 2026, then I tried it again several times over the course of six months on different destinations. But it was the Berlin test that was the most revealing, because Berlin is a city that challenges any planner: it is huge (892 km² in area), the neighborhoods are very far apart, and the risk of wasting hours on transportation is very high if you don't organize the days well by geographical areas.
What I asked the AI and how it responded

I entered the real parameters of my trip into the planner: arriving Thursday evening at Tegel (now reopened as Berlin Brandenburg alternative for charter flights), departing Sunday morning, medium budget, main interest in 20th-century history and street art, no interest in shopping or nightlife. I also specified that I had already visited the Reichstag and the Brandenburg Gate on a previous trip. Secret World processed an itinerary in less than 40 seconds, and the first thing that struck me was the geographical logic: day 1 focused on Mitte and Kreuzberg, day 2 on Friedrichshain and the East Side Gallery, day 3 on Prenzlauer Berg and Wedding.
For each attraction, the AI provided concrete and useful details: the Jewish Museum (Lindenstraße 9-14) takes about 2.5 hours, costs 8 euros, and is recommended in the early morning to avoid school groups. The Topography of Terror is free and takes 1.5 hours to visit. The East Side Gallery is outdoors, so zero costs and flexible on timings. These are not trivial details: they are exactly the information you need to build a day that makes sense, without finding yourself at 5 PM in front of a museum that closes at 6 after walking 4 km.
The Berlin itinerary: how optimized was it really?
I followed the proposed itinerary for the second day, the one in Friedrichshain, and I must admit that the sequence was almost perfect. It started from Karl-Marx-Allee (Soviet architecture, external visit, 30 minutes), then continued on foot to the East Side Gallery (1.3 km, about 1 hour of visit), then took the U1 to Warschauer Straße for the RAW-Gelände, the abandoned industrial complex that has become a creative hub. Everything was calculated with realistic times, not the optimistic ones you find on other apps where every move seems to take 5 minutes when in reality it takes you 20.
The only correction I made: the AI had suggested having lunch at Markthalle Neun in Kreuzberg, which is only open on Thursday evenings and Saturday mornings. A detail error that made me lose a few minutes, but I easily resolved it by asking the AI for an alternative: it suggested Burgermeister under the U1 bridge at Schlesisches Tor, a great and authentic choice. This conversational exchange is one of the real strengths of the tool.
Honest comparison with Wanderlog and other competitors
I used Wanderlog in parallel for the same trip to Berlin. Wanderlog is great for visualizing routes on a map and for collaborating with other travelers, but the AI component for automatic planning is still quite basic in 2026: it tends to suggest the most obvious attractions without true personalization, and it does not intelligently take into account opening times or the actual distances between places. It is an excellent tool as a shared travel agenda, less so as a generator of smart itineraries.
Compared to TripIt and Google Travel, Secret World stands out for its ability to reason about preferences in a more nuanced way. It doesn't just give you a list: it builds a travel narrative that takes into account pace, fatigue, and logistics. For Berlin, where the temptation is to cram everything into three days and end up exhausted, this approach makes a real difference.
Final vote: 9/10, here's why it's not 10
My rating for Secret World AI Trip Planner after six months of use is 9 out of 10. The missing point is precisely that error regarding the hours of Markthalle Neun, which indicates that the database on events and seasonal hours still has some gaps. Furthermore, for very small cities or off-the-beaten-path destinations, the quality of suggestions decreases compared to metropolises like Berlin, Barcelona, or Tokyo, where the training data is evidently richer.
But for what it promises, namely transforming a chaotic list of wishes into a walkable, intelligent, and personalized itinerary, Secret World really works. If you are planning a trip to Berlin or any other European city in 2026, try Secret World AI Trip Planner for free at secretworld.ai and build your itinerary in less than a minute: it's the fastest way to stop wasting time and truly start traveling.
