Authors and reviewers on Learn Korean Hangul have separate jobs. AI models draft each lesson from the site's curriculum plan, a second model checks it, and Min-ji Park, a Korean language teacher based in Seoul, reviews the Korean before anything is published. She reviewed and signed off every page on 15 October 2026.
Key facts
- Lessons are drafted with AI models from the curriculum plan and checked by a second model.
- Min-ji Park, a Korean language teacher, reviews the Korean in every lesson before publication.
- Nothing goes live until she has signed it off.
- She reviewed and signed off every page on 15 October 2026.
Who Writes the Lessons?
AI models write the first draft of every lesson, glossary entry, phrase page and tool page, working from the site's curriculum plan. No human author is named on the lessons, and the pages carry no invented bylines. Min-ji Park reviews the lessons; she does not write them. The site owner decides what is published, but the owner is not the author of the Korean content.
This matters for a language site, because readers often assume that a Korean speaker wrote a lesson. Here the drafting is done by models, and a Korean teacher checks the Korean before it reaches you. The editorial policy explains each stage of the process, and how we use AI lists the tasks a model performs.
Next, meet the person who reviews the Korean.
Who Reviews the Korean?
Min-ji Park is the site's Korean reviewer. She checks the Korean in every lesson before it is published, and her sign-off is the last step before a page goes live.
Min-Ji Park, Korean Language Teacher
Min-ji Park is a Korean Language Teacher and Curriculum Writer based in Seoul, South Korea. She is a native Korean speaker with more than 10 years of experience teaching Korean as a foreign language.
She has taught adult beginners, university exchange students, and professionals preparing for work or study in Korea, both in classrooms and online. Her teaching focuses on Hangul, everyday conversation, grammar patterns, honorifics, pronunciation and preparation for TOPIK, the Test of Proficiency in Korean.
In her work she pays attention to the mistakes she sees students make. Three come up again and again: mixing formal and casual speech, confusing the particles 은/는 and 이/가, and missing the sound changes that happen between syllables. A draft can be grammatical and still get these points wrong for the situation, so they are a natural focus for her review.
Min-ji reviewed and signed off every page on 15 October 2026, so each page carries her name as its reviewer and the review date. A photo and links to her teaching profiles may be added later, once the owner supplies them.
What Min-Ji Checks in Each Lesson
Before a lesson is published, Min-ji reviews its Korean for five things:
- Natural phrasing: whether each sentence sounds like something a Korean speaker would actually say, not only whether it is grammatical.
- Spelling: that every Korean word is spelled correctly.
- Politeness level: that each example uses the right speech level and honorifics for the situation it describes.
- Pronunciation notes: that bracketed pronunciations and explanations of sound changes are correct.
- Examples: that example sentences are natural and suit the level of the lesson.
Where she disagrees with the draft, the lesson is corrected before it goes live. Fixes made after publication are recorded in the corrections log.
Next, the roles table shows who or what does each job.
Authors and Reviewers: Roles in Producing a Page
Four roles go into every page. The table shows each role, who fills it and what that role can and cannot confirm.
| Role | Who fills it | What it can confirm | What it cannot confirm |
|---|---|---|---|
| Drafting | AI models, working from the curriculum plan | Structure, plain English, examples, links to related pages | That a Korean form sounds natural to a native speaker |
| Model review | A second AI model | Consistency, contradictions, rule accuracy against published standards, learner clarity | Naturalness, the right politeness level for a real situation |
| Korean review | Min-ji Park, Korean language teacher | Natural phrasing, spelling, politeness level, pronunciation notes and examples | That a page can never contain an error; corrections still apply |
| Site owner | The site owner | Publishing decisions, scope, policies | The owner makes no claim to review the Korean |
Only the Korean review row can make a page ready to publish, and Min-ji Park completed that step for every page on 15 October 2026.
The next section describes how the checking is ordered.
The Six Quality Gates
A page passes through six quality gates, and only the Korean review can set the human-reviewed label. The gates run in this order.
- Registry check. A script confirms the page's metadata lengths, that no other page targets the same main keyword, its parent page, its prerequisites and its link targets before drafting starts.
- Draft check. After drafting, a script confirms the frontmatter, one H1, no skipped heading levels, 4 to 6 FAQ items, working internal links and the word-count target.
- Model review. A second model checks Korean accuracy against the rules of the National Institute of Korean Language (국립국어원), contradictions, learner clarity, whether the page delivers what its brief promised, and link relevance. It applies fixes and lists any doubts for Min-ji.
- Korean review. Min-ji Park reviews the Korean in the lesson: natural phrasing, spelling, politeness level, pronunciation notes and examples. Nothing goes live until she signs it off. She completed this gate for every page on 15 October 2026.
- Build checks. At site build, content schemas and structured data are validated, links are checked in the rendered HTML, and automated accessibility and keyboard checks run.
- Design review. Each page template is reviewed against the site's design quality criteria in light and dark themes.
Gates 1 and 2 are automated. Gate 3 is performed by an AI model. Gate 4 is the human step: a page that has not passed it carries the generated or model-reviewed label and is not published. Gates 5 and 6 test the page as a product and say nothing about Korean accuracy.
Next, a sign-off is not the end of the story.
When Is a Lesson Reviewed Again?
A sign-off covers the lesson as it stood on the day Min-ji checked it. A lesson goes back to her for review in three situations:
- Before a major update. A rewritten section or new examples are reviewed before the updated page goes live.
- When learners keep asking about the same point. Repeated questions suggest that an explanation is unclear or wrong, so the lesson is checked again.
- When the TOPIK format changes. Lessons that prepare for the test are reviewed again so that they match the current format.
A corrected Korean form also goes back to her before the fixed page is published, as the corrections page explains.
Next comes how you can tell, on any page, what review has happened.
How Bylines and Labels Show Review
Every lesson page carries a short block that states its status, so you can see at a glance how much checking it has had. The block shows the page's review label, the audio status and the date of the last substantive update.
The byline rule is strict. A page shows the byline "Reviewed by Min-ji Park, Korean language teacher", together with the date of her review, only after she has signed that page off. A page without her sign-off shows no reviewer byline and no review date; its block says that Korean review is pending. Every page now shows her byline and the review date, 15 October 2026.
| Label | What it means | Pages with this label today |
|---|---|---|
| Generated | Drafted by a model and passed the automated checks | Internal drafts only |
| Model-reviewed | Also checked by a second model against the standards | Internal drafts only |
| Human-reviewed | Min-ji Park reviewed the Korean and signed the page off | Every published page |
The reviewer block shows only information that exists in the page record, and the record gains a reviewer name and date only when she signs off. The block never fills the space with a placeholder person or an estimated date.
Next, how teachers and learners can help.
Can Teachers and Learners Help?
Yes. Anyone can report a wrong form or suggest a better example through the corrections page, with the page address, the Korean text shown and the form you believe is correct. Each suggestion is checked against the language standards, and a changed Korean form goes to Min-ji before it is published.
For anything else, such as an offer to help in another way, use the contact page. Smaller help counts too: reporting a single wrong form helps every reader of that page. Return to About Learn Korean Hangul for the full picture of what the site does and does not do.
Frequently Asked Questions
Is any lesson published before Min-ji Park reviews it? No. Lessons are drafted by AI models from the curriculum plan and checked by a second model, but nothing goes live until Min-ji Park has reviewed its Korean and signed it off: phrasing, spelling, politeness level, pronunciation notes and examples. If you still find a mistake later, the corrections page explains how to report it.
Does Min-ji Park write the lessons? No. AI models draft the lessons from the site's curriculum plan, and a second model checks them. Min-ji reviews the Korean in each lesson before publication and asks for changes where it is unnatural or wrong. She is the reviewer, not the author, and no page names her as its author.
Why does every page show her name as reviewer? Because Min-ji Park reviewed and signed off every page on 15 October 2026. Each page shows her name as reviewer, the review date and the human-reviewed label. New or changed content goes through her review and sign-off before it is published.
Can teachers suggest edits without becoming reviewers? Yes. Anyone can report an error or suggest a better example through the corrections process, with the page address, the Korean text shown and the form you believe is correct. A suggestion is checked against the language standards. It does not make the sender a reviewer, and it does not change a page's review label.
Who owns the site, and are they Korean? The site has an owner who makes publishing decisions. This page does not yet name the owner or an organisation, and it makes no claim about the owner's nationality or language background. Any such details will be added only when the owner supplies them and chooses to publish them.
Does a model-reviewed label mean a native speaker checked the page? No. A model-reviewed label means a second AI model checked the page against the language standards and a checklist. That draft status alone does not record a human review. Only the human-reviewed label means Min-ji Park reviewed the Korean and signed the page off, and every published page now carries that label.
