Introduction: I Thought I Was Using AI, Turns Out I Was on Autopilot
Using the ChatGPT App in Portugal was not something I planned or optimized ahead of time. It happened naturally, the same way most travel decisions do, out of convenience and curiosity. Like many people, I treated it as a general AI travel assistant without thinking much about how I was using it.
It was only after sharing my usage history with a friend that I had a real AHA moment. I realized I had been relying almost entirely on Auto instead of Thinking. Auto worked well most of the time, but it failed in situations where real-world context, location accuracy, and timing mattered.
That realization changed how I now use the ChatGPT mobile app, especially while traveling abroad.
Early Uses: No Different Than Home
Airport Questions and Familiar Comfort
My first two uses of the app in Portugal did not feel travel specific at all. They were the same type of questions I would ask at home.
One involved a WiFi issue in the KLM Lounge. The other was a question about checked bag transfer during international travel. Both were simple, informational requests. ChatGPT responded clearly and accurately, just as expected.
At this point, the app felt familiar. Helpful, fast, and no different from everyday use.
When the App Truly Shined: Visual Input and Speed
A Poster, Coordinates, and an Instant Answer
The first moment that truly stood out happened unexpectedly. I saw a poster in Lisbon that showed nothing but geographic coordinates. Instead of opening Google Maps and typing them in manually, I took a picture and asked ChatGPT where the coordinates led.
The answer came back quickly and correctly. This saved time and effort, and it was noticeably faster than traditional search. This was my first real indication that image-based AI combined with context is where the ChatGPT app excels while traveling.
Language Barriers Solved in Real Time
Grocery Store Confusion Turned Into Clarity
The next use case came from an experience I had never dealt with before while traveling, buying milk abroad with a toddler.
In a Portuguese grocery store, I was looking at multiple milk options with labels that were not in English. I took a photo and asked ChatGPT which one was whole milk and what the other options meant.
The explanation was clear, practical, and easy to understand. I knew exactly what to buy and why the other choices were different.
From Milk to Menus
Later that same day, the app helped again at dinner. The restaurant menu was entirely in Italian. I took photos of the Antipasti section and asked ChatGPT to break it down simply in English.
This made ordering easier and more enjoyable. We understood what we were ordering and felt more confident in our choices. We used the app again for other sections of the menu with the same success.
Going Deeper: Shelf-Stable Milk and Parenting Abroad
The grocery store experience led to a deeper set of questions about shelf-stable milk. I asked several follow-up questions in the same session.
Why shelf-stable milk is common in Europe
How it differs from refrigerated milk
Whether it is normal for toddlers
This turned into a short learning experience that filled a real knowledge gap. While I travel often, grocery shopping for a toddler abroad was new territory for me. In this context, the app worked as a learning tool, not just a translator.
Up to this point, Using the ChatGPT App in Portugal felt extremely reliable.
The Turning Point: Location-Based Questions in the Real World
Finding the Hop On Hop Off Bus
Eventually, we decided to use the app for something more situational. We asked where the closest hop on hop off bus stop was near our hotel in Lisbon.
ChatGPT gave us an answer. Since this was our first time using it for location-based guidance, we decided to fact check it. The information was correct.
That success gave us confidence to try similar requests later in the day.
When Auto Failed: A Frustrating Miss
The Green Line Issue
Later, after getting off the bus in a different part of Lisbon, we asked another location-specific question. We wanted to find the closest Green Line hop on hop off stop near our current location.
ChatGPT told us the nearest stop was about an eight minute walk away.
In reality, the stop it pointed us to was nearly twenty minutes away and was not the closest option. When I questioned the response, the app acknowledged the mistake and provided the correct stop, which was only about six minutes away.
This moment was frustrating because it was time sensitive. We were outside, tired, and making decisions in real time. After that experience, we stopped using the app for in-the-moment navigation.
The AHA Moment: Auto vs Thinking
It was later, while reviewing my usage history with a friend, that everything clicked.
I had been using Auto almost exclusively.
Auto performed well for translation, explanations, and image interpretation. It struggled when accuracy and real-time location context mattered most. That was when I switched to Thinking and have stayed there since.
Would Thinking have provided the correct stop the first time? I am not sure. What I do know is that switching modes changed how I approach the app. I now use it more deliberately and with a clearer understanding of its strengths and limits.
FAQs About Using the ChatGPT App in Portugal
Is the ChatGPT app useful while traveling abroad?
Yes. It is especially useful for translation, visual interpretation, and quick explanations while traveling internationally.
Can ChatGPT replace Google Maps for navigation?
No. It works best as a supplement to traditional navigation apps, not a replacement.
Is photo input reliable for menus and labels?
Based on my experience, yes. It consistently reduced friction and saved time.
What is the difference between Auto and Thinking modes?
Auto prioritizes speed and conversational responses. Thinking focuses more on reasoning, validation, and accuracy.
Is ChatGPT helpful for parents traveling with kids?
Yes. It helped with food choices, nutrition questions, and real-time decision making.
Would you rely on ChatGPT again for location-based questions?
Only with verification and a more cautious approach.
Conclusion: A Tool Is Only as Good as How You Use It
Using the ChatGPT App in Portugal taught me that the biggest limitation was not the AI itself, but how I was using it.
I was consuming answers instead of evaluating them. I was relying on Auto instead of Thinking.
Now, I use the app with more intention. I still trust it, but I verify when context and accuracy matter. Understanding when the tool excels and when it needs human judgment has made it far more valuable.
