Hello. Good morning? It is almost lunchtime.

This letter is not a lucky letter. I hope you chew it over carefully and see whether it brings you luck, helps with small tasks, or changes your life.

2026-002

This letter is about the topic I heard most often as we moved from 2025 into 2026.

“It looks like you are doing a lot of different things. When do you sleep?” “You seem to be working for organization A and also for customer B. Do you really have enough time?” “You move between Vietnam and Seoul. How can we work together?”

In other words, these are the questions I hear most often from friends around me and from people who run organizations. This letter is both an explanation and a story about change.

While having a meal with a friend’s couple, I heard a funny story. The husband in that couple has a truly enjoyable hobby: music. He plays guitar, sings, and sometimes writes a little music. He is not a full-time professional, but it is a hobby and an important part of his life. He said everything changed after he met a service called Suno. Starting from a tiny hummed melody or a similar seed of his own, he first built a basic backing track, then filled in the detailed parts that would normally require professional session players, and used Suno to make the music feel like a polished production. He said it was one of the most surprising experiences he had recently. Hearing that story over dinner, I confirmed a few important things.

People at different levels can have very distinct experiences by using AI tools that cost only a few tens of thousands of won. With AI tools, humans intervene and control the middle, creating new forms of creativity.

I told him it felt like one of the most genuinely good AI use cases I had heard recently, and that it was really impressive. It was just an episode from dinner, but he also said he was planning to publish his own work soon. (Four months later, I started making songs with Suno too. Not because I needed creative songs, but because I needed background music. In Choo Sung-hoon’s YouTube videos, songs like that always appear at the end.)

This happened in Hanoi, Vietnam, last year. I went in while preparing for a concert, and I had absolutely no local information at all. Aside from going to Da Nang for travel, I had never entered any region with so little advance research. I had to manage local drivers for the artists and staff, and I worked with Vietnamese staff at a Ho Chi Minh-based company that had contracted those drivers. Detailed communication was hard in short English, and there were many problems. In the end, the accidents we expected happened one by one, and most of the Vietnamese staff except for the Koreans were too busy looking at the artists. The staff were shocked and screaming as they watched the viral clips spread across TikTok. Fortunately, the concert ended without any incident, and Korean staff held back the people who rushed toward the artist, so we finished the job without any problems.

During that process, we used the Zalo channel to carefully invite drivers and interpreters, and for Korean staff who were not used to English, we pressed the auto-translation button so they could understand Vietnamese in Korean. In the middle of that fast-moving on-site rush, we checked information and carried out the concierge work while speaking in Korean. Right now I am running an Online Concierge Project where local Vietnamese staff guide travelers in Zalo chat rooms when they travel on their own. Korean people use Korean, Vietnamese people use Vietnamese, and everyone checks information safely while traveling.

If someone asks how I managed to communicate so much while moving around Vietnam last year, more than 60 percent of the work was handled by an app called Zalo. Was there really anyone using that app in travel in this way? This year, the first thing I want to do when I go back to Vietnam is meet the development team behind Zalo. I really want to praise them. I want to tell them that thanks to them, I was able to start this work. (I want to meet the Zalo team ^^)

Many people say that overseas service subscriptions costing 40,000 to 50,000 won per month or more are too expensive. It feels like you are not using them much, but money keeps going out. So even when you carefully connect a company domain and provide Google Suite, most people delay payment or end up cutting off the related services. ChatGPT appeared, and people connected it for 20,000 won a month and started paying for it. Then Gemini improved beyond ChatGPT, so they switched back to Google and pay for Gemini too, using both.

To use ChatGPT publicly at a company for a shared goal, we create one shared email account. Then about 20 employees can use the same ChatGPT setup together. But writing shared goals and questions in a public setting is too difficult for people working in Korea, and in reality it almost never happens. A group can pay around 20,000 won together, create a shared mailbox like key@textconsulting.io, and use it by sharing the password.

If one account is created through the domain the company uses, Gemini Pro can be attached directly to the company’s Google Drive. We attach the AI to the shared company folder, use it right away, analyze content, translate into multiple languages, and even translate and summarize materials written in Vietnamese. One of the biggest time savers last year was managing Google Chrome accounts by organization, organizing passwords, and not wasting time logging in or changing passwords for each task, while quickly doing work based on what AI analyzed and translated. Right now, various companies are making similar tools and applying them inside companies at a cost of several million won a month. They replicate these patterns, build separate servers, and sell similar tools to government organizations. Of course, they use things that perform worse than GPT or Gemini and sell them for hundreds of times the price.

One lesson I drew from reviewing things in several ways at the start of 2026 was this: with very little human resource, the reason I could do decent work and still grow the client base was that I spent time with those tools and applied them to the organization quickly. While applying the same approach to GF’s event operations work, I replicated and modified the pattern in a similar way. Likewise, I felt the business area I had through Text Consulting Group was expanding quickly.

This letter is written at the end of each month and sent to you. Let me briefly introduce the service.

This service is called The Letter. It is, quite literally, a letter. I made it while thinking about the Christmas letters and gifts I used to send to friends when I was young. It was created for people who work directly or indirectly with Text Consulting Group and Han Woon-jang. I began planning a newsletter for existing clients back in 2022. While thinking about various ways to send a newsletter, I decided to write an actual paper letter. This letter will be mailed to your home or registered address at the end of each month. I plan to use the cheapest postal rate rather than registered mail. I want to seal it so that it feels more analog.

About three months after a letter is sent, I send the same content again by email. With a three-month delay, it is also sent free of charge to email subscribers. Paid subscribers will also receive it. If a business owner requests it, it can also be sent to employees regardless of the size of the organization.
