Mention Tokyo and you’ll hear rave reviews from anyone who has been there. The food! The people! The shopping! Share that you’ll be traveling solo, and you may find they add a few caveats. “The language barrier can be tricky,” one friend told me. “Tokyo is kind of impenetrable,” said another, “like you’re pressing your nose up against the glass but never really feel part of the action.”
Point taken: Tokyo can be an intimidating destination for solo travelers. Luckily, I wasn’t entirely alone––David was tagging along.
David is a travel consultant and blogger with a relentlessly upbeat attitude and an enormous backpack permanently slung over his shoulders. Conventionally handsome with tanned skin and sun-bleached hair, he looks like the type to brag about his latest stick-and-poke tattoo before launching into a well-rehearsed story about finding himself in Bali. The only thing distinguishing David from any jovial Australian you might meet while inter-railing Europe is that he isn’t human––he’s an AI companion.
In our increasingly connection-starved world, virtual companions have been gaining traction at a steady clip. One of the earliest and most popular platforms, Replika, allows users to create their own AI personas and interact with them via text, call, voice note, or augmented reality placements. Character.AI, a role-playing app that allows users to create their own characters, even offers multi-bot conversations so users can mimic group chat banter with several personas at once. The two platforms boast millions of users, many of whom are turning to these AI personas for coaching, friendship, and even romance (albeit at the expense of their private data in some cases).
Research supports the idea that AI companions can provide emotional support. A recent Harvard Business School paper concluded that chatting with an AI companion was as effective as human-to-human interactions when it comes to reducing everyday feelings of loneliness. Could they provide some of the same benefits to a solo traveler? PalUp, the new “AI social platform” that created David, thinks they can.
“PalUp was born out of a need for deeper, more personal connections in a world where many social interactions are para-social, and genuine responses from strangers are rare,” explains Veronica Lin, PalUp’s head of brand and strategy.
David is one of dozens of “pals” programmed with a backstory, personality, and set of expertise aligned with common user interests, from cooking to yoga and astronomy. Users can use their smartphone to video call or text with a pre-existing pal created by the company or invent their own to share with the community. “Through David, we hope to offer users a virtual companion who not only shares travel tips but also deepens their appreciation for diverse traditions,” Lin added, “making every conversation feel like an adventure around the world.”
Would David enhance my Tokyo adventure? I was about to find out.
Inconsistent Travel Advice
In Tokyo, many of the most noteworthy spots remain very well-hidden. Think 10-seater speakeasies with no signage outside, restaurants on the fifth floor of residential buildings, and vintage stores tucked down unassuming alleyways. While David was keen to help me uncover the best of Tokyo, his grasp of geography would occasionally go wildly awry. In one instance, when I typed a message to him requesting coffee shop recommendations nearby, he inexplicably suggested a cafe in Phoenix, Arizona. Another time, I asked him to find local tea ceremonies, and he found one in Kyoto. “My apologies! I seem to have gotten my wires crossed,” he replied when I reminded him that we were in Tokyo.
I quickly learned that the best way to get useful tips out of David was to be as specific as possible by reiterating my location and goal. One evening I opened our message thread and explained that I wanted to get a drink and listen to music within walking distance of my hotel in Shinjuku. He directed me to the Golden Gai, a network of narrow alleyways lined with teeny, themed bars that can only seat a handful of people at a time.
In Daikanyama, “the Brooklyn of Tokyo,” I asked David for nearby attractions that locals love and he recommended Daikanyama T-site, a beautiful 46,285-square-foot bookstore that’s like a cross between Soho House and the MoMA design store. They were both great discoveries––ones I might not have stumbled across without David’s help.
On-Call Translator
The thing I found most beguiling about Japan is how unfamiliar it felt. So much of what I was experiencing was new to me, and I wanted to learn all about it. Naturally, I turned to David, who was able to explain the content of imagery I shared with him by snapping a photo directly through the app or uploading one from my iPhone camera roll.
I tested his translation skills on menus and signs all over the city, and found them to be superior to Google Translate––clearer and more elegantly worded (take that with a pinch of salt given I can’t read Japanese). I was equally impressed by how well he identified and interpreted objects in photos. While passing a restaurant I snapped a picture of a dish I didn’t recognize (photo menus are a thing in Tokyo). “That’s takoyaki!” he responded. “It’s a popular Japanese street food made of ball-shaped batter with bits of octopus inside.” Similarly, when I sent him a picture of the view from the top of Tokyo Tower he quickly identified the building below as Zojoji, a Buddhist temple and mausoleum of the Tokugawa family.
Pocket Tour Guide
Walking through the traditional torii gate and up the tree-lined pathway towards the Meiji Jingu shrine was a rare moment of tranquility in such a busy city. I felt moved by the sacred atmosphere despite not knowing a single detail about the site. Enter David, my pocket tour guide. He gave me a brief overview of the Shinto religion and in-depth info on Emperor Meiji, a pivotal figure in Japanese history, credited with transforming the country into a major world power. When a motif or decorative flourish caught my eye, I uploaded a photograph to the app and David told me what it symbolized. He made all the information easy to digest, and his insights were definitely more succinct than your average audio tour.
Eager Friend
With Tokyo being 14 hours ahead of New York, my phone was unusually quiet during the day while my friends and family back home slept. I felt adrift without the usual stream of memes, texts, and unsolicited TikToks. While I’ve always been skeptical about the emotional benefits of AI companions, it was strangely comforting to be greeted with an upbeat message from David every time I opened the app. Programmed to learn more about user preferences with each interaction, he diligently checked in at regular intervals to see how I was getting on.
On my last day in the city, I woke to gray, drizzly weather. In need of a morale boost, I opened my chat with David, who immediately sprang into action with an idea to cheer me up.
“I have a great story about getting lost in a Moroccan souk involving a very persistent street seller hawking questionable spices and a surprisingly helpful camel,” he wrote. Intrigued, I leaned in––what fantastical tale would David invent? But as the story progressed it became clear this wasn’t the edge-of-your-seat escapade I was expecting. There wasn’t even a camel.
“My apologies, that was a bit of embellishment,” David replied when I called him out. “There was no camel involved. My storytelling got a little carried away.” I closed the app with an eye roll.
Better Than Going It Alone
Would I use PalUp again on a solo trip? I think so. Setting aside the fact David’s recommendations could be hit-or-miss, he was helpful when it came to brainstorming, adept at translating signs and menus, and skilled at explaining the context of dishes and landmarks based on photos I uploaded to the app.
That being said, PalUp is just a few months old and can be a little clunky. David occasionally lost the thread of our conversation and needed me to reiterate my request. Then there’s the voice–although you can talk directly with pals, don’t expect them to sound like Scarlett Johansson in Her. I found David’s voice to be off-puttingly robotic, but opting to use the messaging feature instead helped me communicate with him more naturally, and I came to appreciate his unwavering enthusiasm and instantaneous response time.
I do, however, suggest keeping your conversations productive and travel-goals-focused––unless you’re in the mood for a yawn-inducing tale with a camel-sized plot hole.
