Short answer: South Korea's AI Basic Act took effect on January 22, 2026, and it reaches AI products built outside Korea if they affect Korean users. If you buy or sell AI tools for Korean customers, the practical questions are simple: does the tool tell users that AI is involved, does it label realistic AI-generated media, can the vendor give you documentation, and does the vendor need a local representative? A one-year grace period on fines gives you time to ask, but not time to ignore it.
This is a trend explainer and a buyer's checklist, not legal advice. It builds on our earlier note on AI agent frameworks in 2026, and goes deeper on what the law means when you pick a vendor. For the wider category, see the AI & ML buyer guide and the AI & ML topic page.
Quick comparison: which tool types raise which questions
The law names generative AI, high-impact AI and very large AI systems as separate tracks. The table below is our reading of how common business tools line up. It is a way to organize questions for vendors, not a legal classification.
| Tool type | Why it matters under the Act | What to ask the vendor | Examples on ProductListo |
|---|---|---|---|
| AI chat assistants and model APIs | Generative AI: users should be told AI is in use and outputs may need labels | How are users notified? Can outputs be marked as AI-generated? | OpenAI, Anthropic, Perplexity |
| AI voice and audio | Realistic synthetic audio is the case the labeling rule targets | Does exported audio carry a label or watermark? | ElevenLabs |
| Customer-support AI agents | Chatbots talk to the public, so the advance-notice duty applies | Is there a clear "you are talking to AI" notice in Korean? | Intercom, Zendesk |
| Hiring and screening software | Hiring is named as a critical sector for high-impact AI | Can the vendor explain decisions and support human review? | Not listed yet |
| Automation platforms | Agents act on your behalf, so records and approvals matter | Are runs logged and can a person approve steps? | Workato, n8n, Make |
What the AI Basic Act actually says
The full name is the Act on the Development of Artificial Intelligence and Establishment of Trust. According to the law-firm summary from Cooley, it took effect on January 22, 2026. The US International Trade Administration's market intelligence page says the Act and its Enforcement Decree took effect on that same date. The IAPP's analysis adds that the Act has three tracks: transparency duties for generative and high-impact AI, safety requirements for frontier models, and governance duties for high-impact systems in sensitive domains.
Who is covered
The Act applies to two kinds of business: those that develop AI and those that offer products or services that use AI. It also reaches AI systems outside Korea if they affect users or markets in Korea. Systems used for national security are excepted. That means a US software company with Korean customers is in scope even with no office in Seoul.
The three categories
- Generative AI means AI that produces text, images, sound or video.
- High-impact AI means AI that significantly affects human life, safety or fundamental rights. Cooley lists healthcare, energy, transportation, hiring and biometric analysis among the critical sectors.
- High-performance AI means systems trained with cumulative compute of at least 10^26 floating-point operations, as clarified by the ministry (MSIT, the Ministry of Science and ICT). Almost no business buyer will touch this category directly, but it affects the largest model providers you may rely on.
What providers must do
For generative AI, operators must tell users in advance that AI is being used, and generated outputs should carry a label. Clear notice is required for AI-generated sound, images or video that are hard to tell from human-made content. The US trade page adds a useful detail on how: inside a service such as a chatbot, a UI notice, logo or pop-up can work, but exported synthetic content is expected to carry clearer labeling. It also says notices and labels should be in Korean.
For high-impact AI, operators should check whether the system qualifies before deployment, give meaningful explanations, create a user protection plan, allow human oversight and keep documentation. For the largest systems, a risk management plan and reporting to MSIT apply.
Who needs a local representative
A foreign AI business with no Korean address or office must appoint a domestic representative if it meets any one of three thresholds. These are total revenue above KRW 1 trillion in the previous year, AI service revenue above KRW 10 billion, or more than one million average daily users in Korea over a set three-month window. The representative handles government inquiries and safety reports. Most small tool vendors will be under all three thresholds. The largest AI platforms are the ones most likely to be over them.
Penalties and the grace period
Cooley reports administrative fines of up to KRW 30 million, about USD 21,000, for failing to notify users of AI use, failing to appoint a required representative, violating a corrective order or refusing an inspection. MSIT can also issue corrective orders, including suspending a service that threatens safety. The US trade page says MSIT is running a grace period of at least one year in 2026 in which fact-finding and administrative fines are generally deferred, except in serious cases such as loss of life or human-rights violations.
Our reading: the money at stake is small for a large company, but a corrective order or a suspended service is a business risk. The grace period is a planning window, not an exemption.
A buyer's checklist for AI tools sold into Korea
Use these questions in procurement or vendor reviews. They work the same way for any country with similar rules, which makes them a good default.
- Notice. Where in the product does the user learn that AI is involved? Ask to see it, in Korean if your users are in Korea.
- Labels. If the tool creates images, video or audio, can exports carry a visible label or embedded marker? Test an export, not just the preview.
- Documentation. Can the vendor give you a description of intended uses and limits, and keep records you can request later?
- Human oversight. For anything that affects people, such as screening or scoring, can a person review or reverse the result?
- Local representative. If the vendor is large and foreign, ask whether it has appointed a domestic representative.
- Language quality. Run real Korean prompts. A tool that gives good English answers but awkward Korean notices will fail your users before any regulator does.
- Data location and billing. Ask about Korean cloud regions, KRW pricing and tax invoices. We have not verified these for the tools above, so ask each vendor directly.
What US teams should check
The US trade page is aimed at US companies, and its advice is practical. First, decide whether your product falls into a regulated category. Second, provide Korean-language notices and label AI-generated content. Third, document risk management and fundamental-rights safeguards. Fourth, set up a local compliance contact where the thresholds require one. The page also points to the AI Basic Act Help Desk run by the Korea Software Industry Association for case-specific questions.
For a small US SaaS team with a few Korean customers, the realistic steps are modest: add a clear AI notice, label exported synthetic media, keep logs, and write down your intended uses. If you sell hiring or health software, look harder at the high-impact rules and talk to counsel.
For teams in South Korea
If you run a business in Korea and buy AI tools, you are the party who will face your customers' questions. Three habits help. Put the vendor's AI notice in your own terms and onboarding, so users see it in Korean. Ask for the vendor's documentation before you sign, not after a complaint. And pick tools that let you export logs, since a record of what the AI did is the simplest answer to most oversight questions.
If you hire freelancers or agencies to build with AI, the same logic applies to their work. Korean marketplaces such as Kmong and Wishket are priced in KRW and support Korean tax invoices, and our freelance marketplaces guide compares them with global options. See also best freelance platforms in 2026 and the head-to-head Kmong vs Wishket.
Why this matters beyond Korea
Korea's Act is one of the first comprehensive AI laws to take effect in Asia, and it uses ideas that appear in other laws: notices, labels, documentation and human oversight. A vendor that can answer the checklist above for Korea can usually answer it for other markets too. That is the real signal to look for when you compare tools. For a related lens, see how search APIs for AI agents and workflow automation tools for developers and AI agents differ on logging and approvals, and self-hosted team chat for regulated teams for data-control questions. If you are choosing support software, compare Intercom vs Zendesk and read the CRM & Sales guide and Communication guide.
Keep records in a format people can read
Most compliance questions come down to being able to show what happened. Agent and chatbot logs are mostly JSON, and a JSON formatter makes a raw record readable in seconds. UrwaTools also has a guide to keeping a readable audit log of AI agent tool calls with JSON, and a separate how-to on writing a plain-language AI disclosure notice for chatbots and AI-generated media. An AI translator can help you draft a first pass of a notice in another language for a native speaker to review. A machine draft is not a substitute for a fluent human check, especially for legal notices.
Which big names are not in our directory yet?
Several widely used AI assistants and model providers are not listed on ProductListo yet, including Google Gemini, Microsoft Copilot and Naver's HyperCLOVA X. We mention them so you can include them in your own review, but we have not reviewed them and make no claims about their compliance.
Are you an AI tool maker selling into Korea?
If your product helps teams meet notice, labeling or logging duties, or you make an AI tool for Korean users, you can submit it to the directory. For sponsored placement or a guest article, see write for us.
