I had three days in Lisbon, a budget of 400 euros, and my head full of names: Belém, Alfama, Sintra, LX Factory. The problem wasn't finding the attractions – it was figuring out how to fit them in without spending hours on trams or going back to the same neighborhood twice. I used Secret World AI Trip Planner for six consecutive months, tested on multiple destinations, but it was the trip to Lisbon that convinced me once and for all that this tool is not just another copy-paste itinerary generator.
I opened the app, I wrote exactly this: "I am in Lisbon for 3 days, starting from Alfama on the first day, I want to see Belém but I don't want to wait in line for two hours at Pastéis de Belém, I have a medium-low budget and I prefer to walk rather than take public transport when possible." What happened next surprised me enough to write this review.
What the AI responded: details that no paper guide gives you
Secret World did not give me a generic list. It built a day-by-day itinerary with precise times. For the first day in Alfama, it suggested arriving at the Castelo de São Jorge at 9:00 when it opens (ticket 15 euros), before the organized groups arrive. It specified that from the castle to the Sé Catedral it is about 400 meters on foot, and that the Miradouro das Portas do Sol is only 5 minutes from the cathedral – perfect for a coffee break with a view of the Tagus. For Belém, on the second day, the AI solved the queue problem on its own: it indicated to go to Pastéis de Belém at 8:30, when the place opens and the lines are still manageable, allowing for a 20-minute stop before reaching the Mosteiro dos Jerónimos (ticket 10 euros, recommended to book online).
The thing that impressed me the most was the geographical coherence of the itinerary. Lisbon is a city of ups and downs that can become a nightmare if not planned well. Secret World organized each day following a logic of real proximity: no senseless jumps from one neighborhood to another. The third day, dedicated to LX Factory and the Santos area, also included the Museu Nacional de Arte Antiga just 10 minutes on foot, with a note specifying free entry on Sunday mornings until 14:00. That kind of detail, concrete and verifiable, is what distinguishes a useful tool from a useless one.
The comparison with Wanderlog: where Secret World really wins
I used Wanderlog in parallel, and it’s fair to say it clearly: Wanderlog is a solid tool for organizing logistics, saving links, and sharing itineraries with other travelers. Its interactive map is well done. But when I asked the integrated AI of Wanderlog for the same type of contextualized itinerary for Lisbon, the response was much more generic: attractions listed without precise times, without consideration of queues, without the geographical logic that Secret World has applied automatically. For those who want a plan that really works in the field, without having to integrate everything manually, the difference is noticeable.
Other competitors like TripIt and Roadtrippers are mainly designed for road trips or for managing already made reservations – useful, but with a different angle. Google Travel remains an aggregator of information, not a true intelligent planner. Secret World positions itself differently: it is an assistant that thinks about the itinerary like a knowledgeable friend of the destination would, not like a search engine.
What doesn't work perfectly yet
Honesty requires mentioning where the tool has room for improvement. On two occasions, the entry price information was slightly outdated – the ticket for the Castelo de São Jorge was listed at 14 euros instead of 15. Nothing serious, but it's worth always checking the updated prices on official websites before departing. Additionally, for very niche destinations or those off the main circuits, the AI tends to be less accurate: it works better in cities with high data density like Lisbon, Barcelona, or Rome.
Another limitation concerns advanced customization: if you have very specific needs – for example, travel with reduced mobility or very specialized thematic itineraries – you need to guide the AI with very precise questions. It's not a serious flaw, but it requires a bit of practice to get the best out of the tool. Over time, I've learned to ask more detailed questions and the results have improved proportionally.
Final vote 9/10: why I recommend it without reservations
After six months and several tested trips, my vote for Secret World AI Trip Planner is 9 out of 10. The missing point is for the room for improvement on real-time pricing and coverage of less popular destinations. But for a city like Lisbon – and for all major European destinations – the tool really works, and it works well. This is not marketing: it is what I experienced firsthand walking between Alfama and Belém with an itinerary that made logistical, economic, and temporal sense.
