Translate to Korean on Your Mac — Honorifics, Hangul, and All

If you regularly communicate with Korean-speaking colleagues or clients, you already know the pain: getting the vocabulary right is only half the battle. Korean has an entire system of speech levels — 존댓말 (formal) and 반말 (casual) — that changes verb endings, particles, and even vocabulary depending on who you are addressing. Getting this wrong does not just sound awkward; in a business context, it can come across as disrespectful.

That is exactly why a generic "translate to Korean" tool is not enough. You need a translation workflow that understands formality, preserves your intent, and outputs clean Hangul script — all without forcing you to leave the app you are working in.

Why Translating to Korean Is Harder Than It Looks

Korean is an agglutinative language: grammatical meaning is packed into suffixes stacked onto verb stems. A single English sentence like "Could you please send the report?" can map to half a dozen Korean variations depending on:

• Honorific level (존댓말 vs. 반말): Are you writing to a senior executive, a peer, or a close friend?
• Written vs. spoken register: Formal written Korean (합쇼체) differs significantly from polite conversational Korean (해요체).
• Cultural nuance: Korean business communication favors indirectness and softening phrases that have no direct English equivalent.

Most translation tools default to a single register and miss these distinctions entirely. The result reads like a textbook exercise, not something a native speaker would actually write.

Translate to Korean With a Custom Prompt in WunderType

WunderType is a macOS menu bar app that lets you build Custom Prompts — small, reusable AI-powered text actions, each with its own keyboard shortcut. Instead of copying text into a browser translator, you select the English text in any app, press your shortcut, and get polished Korean back in place.

Here is an example Custom Prompt set up for Korean translation:

• Name: Korean Translation Boost
• Shortcut: ⌥⇧⌘T
• Instruction: "Translate the selected English text into natural Korean. Use polite formal register (존댓말, 합쇼체) suitable for professional correspondence. Preserve the sender's tone and intent. Output Hangul only — no romanization."

Before and After

Suppose you have the following English draft sitting in your email composer:

I need to send this email to my Korean client, Mr. Park. I'm trying to say I appreciate the opportunity, but I'm worried about the project timeline. Honestly, it feels a little complicated.

After pressing ⌥⇧⌘T, WunderType returns:

박 씨, 좋은 기회 주셔서 감사합니다. 다만, 프로젝트 일정에 약간 우려되는 부분이 있습니다. 솔직히 조금 복잡하게 느껴지네요.

Notice how the output uses appropriate honorifics for addressing a client, maintains the polite-but-candid tone of the original, and delivers everything in clean Hangul — no romanization cluttering the message.

Handling Honorifics and Formality Automatically

The real power here is in the instruction you write for your Custom Prompt. Because you control the system prompt, you can tailor it precisely:

• Need casual Korean for a chat with a friend? Create a second prompt that specifies 반말 and 해체.
• Writing a formal business proposal? Specify 합쇼체 and request Sino-Korean vocabulary where appropriate.
• Want to translate your name in Korean? Add a note to your prompt instruction to transliterate proper nouns into Hangul phonetically.

You can have as many Custom Prompts as you need — one per formality level, one per recipient type, or even one per project.

Where This Fits Into Your Workflow

Because WunderType operates at the system level on macOS, your Korean translation shortcut works everywhere:

• Email clients — Draft in English, select, translate, send.
• Slack and messaging apps — Respond to Korean teammates without switching tools.
• Documents and presentations — Localize slides or reports paragraph by paragraph.
• Web forms and CRMs — Enter Korean text directly into any input field.

No browser tabs. No copy-paste chains. No losing your place.
