I was at the Mercat de la Boqueria at 9 in the morning, with three days ahead and no concrete plan. I had booked the hotel in the Gothic Quarter, I knew I wanted to see the Sagrada Família and Casa Batlló, but I had no idea how to connect everything sensibly without wasting hours in line or walking unnecessary kilometers. It was at that moment that I opened Secret World AI Trip Planner and started using it seriously, after having tested it for six months on other destinations. Barcelona was the proving ground.
I used the app asking for something very specific: a three-day itinerary starting from the Gothic Quarter, prioritizing Gaudí's works, some beach time in the afternoon, and a medium budget around 60-80 euros per day excluding accommodation. I didn't want contemporary art museums and preferred lunches in local, non-touristy places. The response came in about 40 seconds.
What the AI responded: concrete itinerary, not generic list
The artificial intelligence of Secret World did not return a list of attractions to copy from Wikipedia. It built a geographically logical route: the first day in the Gràcia neighborhood and surroundings, with a visit to the Sagrada Família (recommended ticket 26 euros with access to the towers, reservation required at least 48 hours in advance), then walking to Parc Güell in about 20 minutes, and in the afternoon heading down to the beach of Barceloneta by metro L5. The second day dedicated to Eixample: Casa Batlló (standard ticket 35 euros, better the evening tour Magic Nights for a different atmosphere), Casa Milà-La Pedrera 200 meters away, and suggested lunch at Cervecería Catalana on Carrer de Mallorca, with tapas costing about 15-20 euros per person.
The third day was the most interesting: the AI suggested the Gothic Quarter and the El Born neighborhood on foot, including the Barcelona Cathedral (free entry early in the morning), the Picasso Museum (14 euros, much shorter line compared to the Sagrada Família) and the Mercat de Santa Caterina as a less crowded alternative to La Boqueria. A detail I appreciated a lot: for each attraction, it indicated the realistic visiting time, not the promotional one. The Sagrada Família: minimum 90 minutes. Parc Güell monumental area: 45 minutes. This really helped me not to rush.
Six months of testing: the strengths that no one mentions
I used Secret World also for Lisbon, Prague, and Amsterdam before arriving in Barcelona. The pattern I noticed is that the AI improves significantly when you give it precise constraints: budget, starting neighborhood, dietary preferences, mobility. The more specific you are, the more useful the output is. In Barcelona, I added the request to avoid the central hours of the day in the most crowded attractions (11-14), and the itinerary was reorganized accordingly, with museum visits in the early morning and outdoor activities in the late afternoon.
Another strong point is the geographical consistency: no absurd jumps from one neighborhood to another as happens with certain automatic planners. In Barcelona, where distances are relatively short but the summer heat can be heavy, having a route that follows a logic of proximity really made a difference. I walked a lot, but never felt like I was wasting energy.
Honest comparison with Wanderlog and other competitors
I used Wanderlog in parallel for the same six months. It is a valid tool for organizing maps and lists, but the AI component is still quite superficial: it tends to suggest the same top-10 attractions that you find on any travel blog, without adapting to your constraints in a truly intelligent way. For Barcelona, Wanderlog gave me an itinerary that included both the Sagrada Família and Camp Nou in the same afternoon, without considering the 40 minutes of metro between the two and the visiting times. Practical for gathering ideas, less useful for truly planning.
TripIt is great for managing existing bookings, but it does not plan. Google Trips has been discontinued. Secret World positions itself in a different space: it is not a booking aggregator, it is a conversational planner that thinks about context. The difference is especially felt when the trip has more variables, as in the case of Barcelona with its neighborhood microclimates and the huge difference between attractions that require reservations and those that are freely accessible.
Final vote 9/10: why it is not 10
The rating is 9 out of 10 for a simple reason: Secret World AI Trip Planner works very well, but it requires you to know what to ask. Less experienced users who ask vague questions receive less precise answers. It is not a serious flaw, but it is honest to point it out. For those who travel frequently and can articulate their preferences, the app becomes almost indispensable. In Barcelona, I saved at least three hours of planning and visited places I would not have found on my own, such as the Bunkers del Carmel, suggested by the AI as an alternative to Tibidabo for the view of the city, with free access and a much more manageable crowd.
If you are planning a trip to Barcelona or any other European city in 2026, I recommend trying Secret World AI Trip Planner before opening any other app. Start with a specific request: neighborhood, budget, interests, limitations. You will see the difference compared to any pre-packaged list. Try Secret World for free and build your personalized itinerary in less than a minute.
