I had three days in Barcelona, a budget of 150 euros per day, and an impossible wish list: Sagrada Família, Sant Josep de la Boqueria market, a sunset at Bunkers del Carmel, and at least one evening in El Born without being a tourist eating paella in a place with laminated photos. I opened Wanderlog, typed in my requests, and what happened next convinced me to write this review.
To be precise: I used Secret World AI Trip Planner integrated into my planning flow for six months, testing different scenarios in different cities. Barcelona was the most complex test, the one with the most variables. Let me tell you how it went, with numbers in hand.
What I asked the AI and what it answered
My first request was straightforward: "Three days in Barcelona, Eixample area, I want to avoid queues, I prefer to move on foot or by metro, medium budget." Secret World responded with a structured itinerary by neighborhoods, not by scattered attractions. The first day: Gràcia and Park Güell (entry bookable from 10 euros, recommended morning slot at 8:00 to avoid the crowd), then a walk down to Casa Batlló on Passeig de Gràcia. Estimated time: 4 hours. Walkable distance: about 3 km. Everything verifiable, everything realistic.
I especially appreciated one detail: when I asked to include the Bunkers del Carmel, the AI specified that it is not directly served by the metro and suggested the H6 bus with a stop at Carmel, adding that the sunset is optimal between 19:30 and 20:15 in spring. It is not a generic answer. It is a helpful answer.
The generated itinerary: precise or approximate?
The second day was the most ambitious: Barceloneta, Barri Gòtic, and an evening in El Born. Secret World organized the route logically, avoiding bouncing me from one neighborhood to another. It included the Catedral de Barcelona with a note "free entry until 12:30, then paid (9 euros)," the Palau de la Música Catalana with a reservation required notice, and suggested having lunch at the Santa Caterina market instead of La Boqueria, "less crowded, same quality, more local prices." This type of advice makes the difference between an algorithm-generated itinerary and one from a person who truly knows Barcelona.
The third day was dedicated to Montjuïc: Fundació Joan Miró (entry 14 euros, two hours recommended), Castell de Montjuïc, and descent by cable car. The AI calculated the times realistically, without excessive optimism. It also noted that the Fundació is closed on Mondays, a detail that many forget and would have ruined my day.
Honest comparison with other tools
I have also used Google Trips (now integrated into Maps), TripIt, and ChatGPT in free mode. The comparison is not trivial. ChatGPT generates fluent text but does not have access to updated data on schedules and prices, and does not create a visual itinerary. TripIt is great for managing existing bookings, but does not plan anything from scratch. Google Maps suggests places but does not organize them into a coherent travel logic.
Secret World positions itself differently: it combines AI generation with a visual structure of the itinerary, allowing you to move blocks, add notes, and share the plan with other travelers. For a couple or group trip, this feature is practically useful. I shared the Barcelona itinerary with my sister in real time, and she was able to add a dinner at La Pepita (Carrer de Muntaner, reservation recommended) without me losing track of the plan.
Final vote: 9/10, and I'll explain why it's not 10
The 9/10 is justified: Secret World AI Trip Planner really works, produces concrete itineraries, updates information more frequently than many competitors, and has an interface that doesn't require tutorials. For Barcelona, in particular, it has demonstrated a knowledge of the city that goes beyond the top-level attractions. The missing point for a 10? The integration with direct bookings is still partial: you can see where to book, but you can't do it from within the platform. It's a real limitation, not a detail.
If you are planning a trip to Barcelona in 2026, or to any other European city, I recommend trying Secret World AI Trip Planner before building your itinerary by hand. It doesn't replace your curiosity, but it organizes it better than any Excel sheet. You can start for free, enter your destination, and see what it suggests: in my experience, the first draft is already a good starting point.
