It sounds translated
Stiff phrasing, the wrong level of politeness, “you” in every line. People can understand it, but it doesn’t sound like a brand they’d trust, and conversions quietly drop.
Korean cultural QA for AI-made marketing
One AI-written line can sink a launch in Korea. Before your ads, copy and visuals go live, a native Korean marketer checks them for tone, nuance and cultural landmines, and tells you exactly what to fix, in plain English.
Starbucks Korea chief dismissed over “Tank Day” promo
A tumbler promotion ran on May 18, the anniversary of the 1980 Gwangju Uprising, with the line “책상에 탁!” Staff later said they had “asked AI for suggestions.”

What AI missed
The problem
AI has made Korean campaigns cheap to produce, and easy to get subtly wrong. In 2026 alone, AI-assisted ads that skipped a human sensitivity check forced public apologies from major brands in Korea. Audiences notice instantly. And they screenshot.
Stiff phrasing, the wrong level of politeness, “you” in every line. People can understand it, but it doesn’t sound like a brand they’d trust, and conversions quietly drop.
AI visuals slip in Japanese or Chinese clothing, signage and props, or render Hangul as near-miss gibberish. To Korean eyes that reads as low effort, or worse, a scam.
A hand gesture, a sunburst pattern, a date, a word with online baggage. In Korea, details this small have led to boycotts and public apologies from major brands.
What we check
Translators check language. We check whether your message will land, with the instincts of someone who has run campaigns for Korean consumers.
Naturalness, translationese, honorific level (존댓말 / 반말), and consistency with your brand voice.
Idioms, humor, holidays and seasons like Seollal and Chuseok, numbers, colors and gifting customs.
Gestures, symbols, clothing, food, settings, and AI-rendered Hangul inside images and video.
History, politics, gender discourse, regional and generational sensitivities, and loaded dates.
Medical-sounding or exaggerated claims, sponsorship disclosures and Korea’s new AI-generated ad labeling rules, flagged for a second look.
Conventions for Naver, Kakao, Instagram, YouTube and app stores: length, CTAs, prices in ₩, date formats.
What you get
Every issue is rated by severity, explained in English, and paired with a ready-to-use Korean fix. Here’s an excerpt from a sample review.
Korea Readiness Report
Fix the two critical items before publishing. Everything else is polish that will lift performance.
Red sunburst background behind the product
The radiating red-and-white rays closely resemble the Rising Sun Flag, widely seen in Korea as a symbol of Japanese imperialism. This alone can trigger backlash and takedown demands.
Model holds the dropper in a thumb-and-index “pinch”
This hand shape has been read as a gender-conflict symbol in Korean online communities. Similar visuals have led to boycotts and public apologies from several major brands since 2021.
당신의 피부가 당신에게 감사할 것입니다.
Reads as: “Your skin will be grateful to you.”
Grammatical, but clearly machine-translated. Korean ads rarely address the reader as “당신”, and repeating it sounds distant, even cold.
여드름을 치료하는 기적의 세럼
Reads as: “A miracle serum that treats acne.”
For a cosmetic, “치료” (treat) and “기적” (miracle) can be viewed as medical or exaggerated claims under Korean advertising rules. Advisory only; confirm with a regulatory specialist.
새해 복 많이 받으새요
Reads as: “Happy New Year” with a spelling mistake
“받으새요” should be “받으세요”. Typos inside images are an instant tell that a post was AI-made.
Customer’s first name set in red
Writing a living person’s name in red is traditionally associated with death. Many Koreans find it unsettling, especially in a celebratory message.

Who reviews your work
I’ve spent nearly 20 years bringing global brands to Korean and Asian audiences. I was on the founding team that took King’s Candy Crush games into Asia, including a TV campaign starring the full cast of Infinite Challenge, Korea’s most iconic variety show. At Netflix, I was a founding member of the APAC programmatic marketing team, running launch campaigns for the service and its originals across the region. Before that, I helped launch Google’s AdMob in Korea and led marketing communications for Canada’s diplomatic mission in Seoul.
Trained as a journalist at the University of Missouri, the world’s first journalism school and repeatedly ranked No. 1 in the US. I read your English brief the way an editor would.
Native Korean with nearly 20 years of marketing to Korean consumers. I read your Korean copy the way your customers will.
AI translation breaks in the gap between what you meant and what Koreans read. That gap is exactly where I work.
Today I lead the Korean business of a global audiobook company as Country Manager. In every one of these roles, the hard part was never the translation. It was knowing what a message would mean to Korean audiences, and what could go wrong.
Now I help global teams who create with AI make sure their Korean content sounds native, feels right and stays out of trouble. I do every review myself. It’s never outsourced and never AI-only.
Why “Vidimus”?
It’s Latin for “we have seen.” In medieval Europe, a vidimus was an official copy in which someone certified they had examined the original document with their own eyes. That’s the promise: every word and frame you send is seen by a human before it reaches Korea.
Anything aimed at Korean audiences: ad copy, social posts, landing pages, emails, app store listings, banners, AI-generated images and short videos with scripts or subtitles. Share links to Google Docs, Figma, Canva, Drive or Dropbox.
Up to 150 words of copy, one static image or banner, or one video up to 60 seconds (with its script or subtitles). Carousel posts count as one asset for up to 5 slides.
