# The firm program an appraiser built with $100-a-month AI (감정평가사가 한 달 100달러 AI로 만든 회사 프로그램)

Tier B (Useful, limited): An informal Korean architecture podcast (Digit TV) in which a certified appraiser and two small-practice architects describe first-hand how they build and use AI tools; concrete and credible, but anecdotal with no time-saved or accuracy figures.

Summary based on the full transcript.

## In short

Episode 2 of the podcast "Critic-Eve" on the Digit TV architecture channel (uploaded 8 November 2026, 65 minutes). Lee Sang-hyup, a certified appraiser at Daehan Appraisal with no coding background, built a desk-appraisal tool on public-data APIs that his firm adopted as its official internal site. Two architects from small practices describe using AI for competition studies, layouts and research. The common lesson: start from what is repetitive or slow in your own work and ask the AI how to remove it.

## Key numbers

- $100 a month: Claude Max subscription the appraiser uses, enough for one or two websites and three or four apps
- about 15 GB: bulk public dataset of apartment official prices he parsed into the internal site
- under 10,000 won a month: hosting cost on the smallest Naver Cloud server, paying only for a public IP
- about three weeks: time a competition planning study for a large public building normally takes, now explored with AI layout options
- 27 units / about 50 people: hanok variants generated for a competition study, and the people shown them

## What it reports

- The appraiser started on Claude Pro for the Excel add-in in February; after a three-to-four-hour one-to-one session with a founder friend in April he moved to Claude Max at $100 a month.
- Desk appraisal: entering an address now pulls land and building records through public-data APIs, replacing one-by-one lookups. Colleagues liked it and executives made it an official internal site; a recent addition maps redevelopment zones with notices and news.
- Apartment official prices: he parsed the roughly 15 GB public bulk download so one click returns prices for a whole complex.
- Hosting moved from his office PC to the smallest Naver Cloud server, under 10,000 won a month; he asks the AI to fix breakages.
- Architects pay for ChatGPT Plus and buy Midjourney or Kling for single months, about 30,000-60,000 won a month in total.
- Hanok study: 27 variants (form, space, material at 100/50/0%) generated with Claude-written prompts and Midjourney, shown to about 50 people to find where a building stops reading as hanok.
- Competition planning: AI produces two or three editable vector layouts that the three-person team critiques as a jury. More competitions are entered, but thinking time, not drawing, caps the number; output per person is up, projects per month are not.
- Legal and regulatory checks stay with people because an error ends a project.

## How they got it

Conversation among practitioners who know each other, summarised from uploader subtitles. Tools are described, not demonstrated in detail.

## Limits

- Informal podcast; no time-saved, cost-saved or accuracy figures for the appraisal tool.
- One appraiser's experience; the firm's adoption is stated, not documented.
- Some speaker names and figures come from subtitles and may contain errors.

## Why it matters for companies

The appraiser's tool is a common pattern: a domain expert with a $100 subscription turns public data and personal frustrations into an internal system the firm then relies on. That creates value fast and a maintenance and support question later, since the tool lives on one person's knowledge and a cheap server. The architects' experience is a useful caution: AI raised output per person, but the number of projects is bounded by judgement time, and high-stakes checks stay manual.

## Key passages in translation

> 그래서 그때부터 100달러를 결제를 해서 맥스 요금제죠. 맥스죠. 고거를 결제해서 지금까지 쭉 쓰고 있습니다.

So from then on I paid $100 for the Max plan, and I have been using it ever since.

> 기본적으로 내가 업무에서 뭐가 불편한가 그쵸. 그거를 가장 고민을 많이 했던 것 같아요.

Basically I thought hardest about what was inconvenient in my own work.

> 법규 같은 거를 만약에 검토를 하더라도 그건 너무 크리티컬한 부분이기 때문에 틀리면 거의 끝장나요.

Even if we review regulations with it, that part is too critical: if it is wrong, it is basically over.
