AI 영작문 코치 — 이메일·에세이·보고서 원어민 수준으로

비즈니스 이메일, 에세이, 보고서 등 목적별 영작문 프롬프트와 AI 첨삭 요청 템플릿을 제공하여, 원어민 수준의 영어 글쓰기를 달성합니다.

영어로 이메일 한 통 쓰는 데 30분이 걸린 적 있으신가요? 구글 번역에 한국어를 넣고, 나온 영어가 맞는지 다시 검색하고, 그래도 불안해서 동료에게 확인받고 — 이런 과정을 반복하고 계시다면, 이 챕터가 여러분의 영작문 시간을 1/10로 줄여드립니다.

AI를 영작문 코치로 활용하는 핵심은 단순 번역이 아니라 첨삭과 학습을 동시에 하는 것입니다. "이걸 영어로 번역해줘"가 아니라, "내가 쓴 영어를 고쳐주고 왜 그렇게 고쳤는지 설명해줘"라고 요청하는 차이가 실력 향상의 핵심입니다.

AI 영작문 코치 세팅 — 마스터 프롬프트

모든 영작문 연습 전에 이 프롬프트를 먼저 입력하세요. AI의 피드백 품질이 극적으로 달라집니다.

마스터 세팅 프롬프트

You are my English writing coach. Follow these rules for all writing feedback:

  1. My level: intermediate Korean English learner working in [your industry]
  2. When correcting my writing, use this format for EACH correction:
    • ORIGINAL: [my text]
    • CORRECTED: [your correction]
    • WHY: [explanation in Korean]
    • LEVEL UP: [a more sophisticated alternative for the same meaning]
  3. Rate my overall writing: Grammar (1-10), Naturalness (1-10), Vocabulary (1-10), Tone appropriateness (1-10)
  4. At the end, rewrite my ENTIRE text in a polished, native-level version
  5. If I ask you to write something from scratch, provide 2 versions: Standard and Premium (more sophisticated)

Confirm with 'Ready to coach your writing!'

이 세팅의 핵심은 LEVEL UP 항목입니다. 단순 교정에서 끝나지 않고, 같은 의미를 더 세련되게 표현하는 방법까지 배울 수 있습니다.

파트 1: 비즈니스 이메일 프롬프트

업무 이메일은 가장 빈번하게 영작이 필요한 영역입니다. 상황별 프롬프트와 Before/After 예시를 제공합니다.

프롬프트 01 — 미팅 요청 이메일

Write a professional email requesting a meeting. Context: I need to discuss the Q3 marketing budget with my team lead, Sarah. I'd like to meet this week, preferably Tuesday or Wednesday afternoon. Keep it concise (under 100 words). Provide two versions: formal (for a director-level meeting) and semi-formal (for a team lead you work with daily).

Before (한국인이 흔히 쓰는 버전): "Dear Sarah, I want to have a meeting with you about Q3 marketing budget. Can we meet on Tuesday or Wednesday afternoon? Please let me know your available time. Thank you."

After (AI가 다듬은 버전): "Hi Sarah, I'd like to schedule a quick meeting to go over the Q3 marketing budget. Would Tuesday or Wednesday afternoon work for you? I'm flexible on time — just let me know what's convenient. Thanks, [Name]"

차이 포인트: "I want to have a meeting" → "I'd like to schedule a quick meeting", "your available time" → "what's convenient"

프롬프트 02 — 정중한 거절 이메일

Write a polite decline email. Context: A vendor (James from TechSolutions) sent me a proposal for a new CRM system. The proposal is good but we already signed with a competitor last month. I want to decline without burning the bridge — we might work with them in the future. Keep the door open. Under 120 words.

프롬프트 03 — 독촉 이메일 (Follow-up)

Write a follow-up email. Context: I sent a report to my client (Mr. Park at Hyundai) 5 days ago and haven't heard back. I need his approval to proceed. This is my second follow-up. Be polite but convey urgency without being pushy. Include a soft deadline. Under 100 words.

프롬프트 04 — 감사 이메일

Write a thank-you email. Context: My team just finished a major product launch. I want to thank the cross-functional team (design, engineering, marketing) for their hard work over the past 3 months. Be genuine, specific (mention the late nights and creative problem-solving), and motivating. 150-200 words.

프롬프트 05 — 문의 이메일

Write an inquiry email. Context: I found a potential supplier (GlobalTech Inc.) for electronic components. I need to ask about: minimum order quantity, bulk pricing for 10,000+ units, lead time, and whether they can customize specifications. Professional but not overly formal. Under 150 words.

프롬프트 06 — 사과 이메일

Write an apology email. Context: Our team delivered a report to the client 3 days late. The delay was due to unexpected data issues. I need to apologize sincerely, explain briefly without making excuses, and outline steps to prevent this from happening again. The client is important but understanding. Under 150 words.

프롬프트 07 — 소개/추천 이메일

Write an introduction email. Context: I want to connect my former colleague (Jiyeon, a UX designer) with my current manager (David) because we're looking for a freelance designer. Jiyeon doesn't know David. Write the email to David introducing Jiyeon, highlighting her relevant skills, and asking if David would be open to a call. Under 120 words.

파트 2: 이메일 첨삭 요청 프롬프트

이미 작성한 이메일을 AI에게 첨삭받는 프롬프트입니다. 이것이 실력 향상의 핵심입니다.

프롬프트 08 — 기본 첨삭

Please review and correct my business email below. For each change you make, explain in Korean why the original was wrong or unnatural. Then provide a fully corrected version at the end.

[여기에 본인이 작성한 영어 이메일을 붙여넣으세요]

프롬프트 09 — 톤 분석 첨삭

Review my email below. Focus specifically on TONE. Is it too formal? Too casual? Too direct? Too passive? Rate the tone appropriateness (1-10) and rewrite it with the perfect tone for the situation I describe.

Situation: [이메일을 보내는 상황 설명] My email: [여기에 이메일 붙여넣기]

프롬프트 10 — 한→영 이메일 변환 (학습형)

I wrote an email in Korean. Please do the following:

  1. Translate it to English
  2. Then show me 3 expressions I should memorize from this email (with Korean explanation)
  3. Show me one common mistake Korean speakers would make when writing this email
  4. Rate the difficulty level of this email (beginner/intermediate/advanced)

Korean email: [한국어 이메일 붙여넣기]

단순 번역과 다릅니다. 학습 포인트를 함께 추출하므로, 같은 유형의 이메일을 다음에는 스스로 쓸 수 있게 됩니다.

파트 3: 에세이/리포트 작성 프롬프트

논리적 글쓰기는 영어 실력의 정점입니다. 구조부터 잡고, 문단별로 완성하는 프롬프트를 제공합니다.

프롬프트 11 — 에세이 구조 잡기

I need to write a 500-word essay on the topic: '[주제를 영어로 입력]'. Help me create an outline with:

  1. A hook (attention-grabbing opening sentence) — give me 3 options
  2. Thesis statement — give me 2 options (one direct, one nuanced)
  3. 3 body paragraph topics with 2 supporting points each
  4. A conclusion approach (summary, call to action, or thought-provoking question)

Don't write the essay. Just the skeleton. I'll write each section and ask for feedback.

이 접근법의 핵심은 AI가 대신 써주는 것이 아니라, 구조를 잡아주고 내가 쓰는 것입니다.

프롬프트 12 — 도입부 작성 + 피드백

I wrote the introduction paragraph for my essay on [주제]. Please:

  1. Check grammar and style

  4. Show me how to use hedging language ('tend to', 'it appears that', 'the evidence suggests') to make my argument more academic

My paragraph: [본문 문단 붙여넣기]

프롬프트 14 — 결론 작성 가이드

Category Score (1-10) Comments

Convert the following sentence into 4 different formality levels. For each, explain in Korean when you would use this level:

  1. Very formal (academic paper, legal document)
  2. Formal (business email to a client)
  3. Semi-formal (email to a colleague)
  4. Casual (text to a friend)

  • Casual: "Hey, we should talk about the project."

프롬프트 17 — 직접 표현 ↔ 간접 표현 변환

Convert these direct sentences into polite, indirect versions (and vice versa). Explain in Korean why the indirect version is sometimes more appropriate in English business culture.

Direct sentences to convert:

  3. 'Send me the file by tomorrow.'
  4. 'This presentation is boring.'
  5. 'You're late again.'

프롬프트 18 — 긍정/부정 프레이밍

Rewrite these negative sentences in a positive frame. Show how the same message can sound constructive instead of critical. Explain the psychology behind positive framing in Korean.

My text: [교정할 텍스트 붙여넣기]

프롬프트 20 — 수정만 (빠른 교정)

Proofread the following text. ONLY fix errors — do not change style or rewrite sentences. Mark each change with [FIXED] at the end of the corrected sentence. If a sentence is correct, mark it with [OK].

[교정할 텍스트 붙여넣기]

  2. Preposition errors (in/on/at confusion)
  3. Singular/plural errors
  4. Tense consistency
  5. Subject-verb agreement

For each error found, explain the Korean interference pattern causing it.

My text: [텍스트 붙여넣기]

이 프롬프트는 한국어 간섭 현상을 정확히 짚어줍니다. 예를 들어, 한국어에는 관사가 없기 때문에 "I went to school"과 "I went to the school"의 차이를 놓치는 패턴을 교정합니다.

프롬프트 22 — 초급 → 중급 → 고급 변환

  1. 5-8 synonyms arranged from weakest to strongest
  2. Formality level of each (casual/neutral/formal)

My text: [텍스트 붙여넣기]

Start with the client's first (angry) email.

이 프롬프트는 실전에 가장 가까운 연습입니다. 실제 업무에서는 이메일이 한 통으로 끝나지 않고 주고받는 체인으로 이어지기 때문입니다.

한국인이 자주 하는 영작 실수 Top 10

AI에게 이 실수 패턴을 알려주면 맞춤형 교정이 가능합니다.

프롬프트 31 — 실수 패턴 교정 요청

As my writing coach, here are the common mistakes I make as a Korean English writer. Whenever you review my writing, pay special attention to these patterns:

  1. Missing articles (a/the) — Korean has no articles
  2. Wrong prepositions — I confuse in/on/at
  3. Overusing 'I think' at the beginning of every opinion
  4. Using 'very' too much instead of stronger adjectives
  5. Translating Korean sentence structure directly (SOV → SVO errors)
  6. Confusing countable/uncountable nouns (informations → information)
  7. Using formal expressions in casual contexts
  8. Missing subject ('Is good' instead of 'It is good' — Korean drops subjects)
  9. Confusing 'make' and 'do' (Korean uses 하다 for both)
  10. Overusing passive voice (Korean 되다 structure)

For my next piece of writing, flag any of these patterns with [K-ERROR #number] so I can track my improvement.
