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.
