I had three days in Barcelona and a list of 40 places to see. The Sagrada Família, the Gothic Quarter, Parc Güell, Barceloneta, the Mercat de Sant Josep de la Boqueria, Montjuïc, Poble Sec. Too many places, zero logical order. I tried Secret World AI Trip Planner for the first time in this chaotic situation, and what it returned surprised me enough to write this review.
I never start with high expectations for these tools. I have already used ChatGPT to plan trips, I have read generic itineraries on blogs that seem to be written by someone who has never set foot in the city. Secret World presents itself differently, as an AI-based planner with updated data and real geographical awareness. Let's see if it's true.
How Secret World Works: My First Session with AI
I opened the app and typed exactly this: “Three days in Barcelona, arriving Thursday evening, leaving Sunday morning early. I want to see modernist architecture, avoid the worst lines, eat well without spending a fortune. I’m not interested in nightlife.” In less than thirty seconds, the AI generated an itinerary divided by days with precise geographical logic: the first day in Eixample to focus on Sagrada Família and Casa Batlló (walking distance about 1.2 km), the second day in the historic center between Barri Gòtic and El Born, the third morning at Parc Güell with a visit to La Pedrera in the afternoon before heading to the airport.
What struck me is that the AI indicated specific times: Sagrada Família at 9:00 AM to avoid the longest line, entry with online reservation at about 26 euros. It noted that Casa Batlló is worth seeing from the outside if the budget is limited (the internal entry exceeds 35 euros), and suggested the Palau del Baró de Quadras as a free alternative nearby. These are not generic tips. Someone has entered real data into this system.
For concretes: what Secret World does better than competitors
The comparison with Google Trips (now defunct) and with tools like Wanderlog or TripIt is merciless on one point: geographical consistency. Wanderlog allows you to add places to a list, but it does not optimize routes intelligently. Secret World, on the other hand, understands that putting Parc Güell on the first day and returning on the third for La Pedrera is a waste of time and transport. In Barcelona, this matters: Parc Güell is in Gràcia, far from Eixample, and getting around by metro or on foot requires planning.
Another strong point is the management of visit times. The AI estimated 2.5 hours for the Sagrada Família (realistic if you include the exterior and the towers), 45 minutes for the Mercat de la Boqueria recommending to go there after 11:00 when tourists thin out slightly, and an hour and a half for the MNAC in Montjuïc. I followed these times and they corresponded to reality almost perfectly. No blog I read before had this accuracy.
Against: where Secret World can improve
Not everything works perfectly. The most obvious limitation I found was when I asked for recommendations on specific restaurants in Poble Sec, a neighborhood I know a bit. The AI suggested correct places like those on Carrer de Blai for pintxos, but the information on hours and prices was generic. For local dining, a manual search on Google Maps remains more reliable.
Second limitation: the AI does not handle weather variables or special events well. In Barcelona during the Mercè or the Diada, certain routes change completely. I had to add this information manually to get adjustments. It would be useful for the system to automatically integrate the city's event calendar.
Final vote: 9/10, and I'll explain why it's not 10
Secret World deserves a 9 out of 10 for a simple reason: it truly solves the main problem for those planning a trip to Barcelona, which is transforming a chaotic list of attractions into a logical route, with realistic timings and a geographical awareness that competitors lack. For three days in a dense city like Barcelona, this is incredibly valuable. I wasted zero time on unnecessary travel and saw everything I wanted to see.
It's not a 10 because the restaurant and local life section is still weak, and because it lacks integration with real-time events. But for architecture, museums, main attractions, and route optimization, it is the most useful tool I have used in 2026. If you are planning a trip to Barcelona and don't want to waste precious days reorganizing itineraries, try Secret World for free on their website: enter your dates, write what you want to see, and let the AI do the heavy lifting for you.
