K-Humanizer: Natural Korean Editing

K-Humanizer gives your AI agent a set of editing rules for Korean writing. It looks for phrasing that sounds translated, overly formal sentences, vague claims, and awkward transitions.

Use it to polish a resume, write to a colleague, clean up a report, or edit the copy in an app. It also covers everyday messages and public posts. The tone follows the reader and the setting, so a casual message stays casual and a work email stays professional.

The default is to edit what you provide. The rules tell the agent to keep names, numbers, technical terms, and the strength of each claim. For career documents, that includes who did the work, what was measured, and whether the work is finished. Writing from notes, reordering experience, or tailoring a resume to a job posting requires a separate request.

Example

Before

고객 문의 분류 체계 고도화를 통해 주간 평균 처리 시간을 18시간에서 11시간으로 크게 개선했습니다.

After

고객 문의 분류 기준을 정리해 주간 평균 처리 시간을 18시간에서 11시간으로 줄였습니다.

The numbers stay the same. The sentence says what changed without the extra formality.

The ZIP includes SKILL.md, six reference guides, Codex agent metadata, installation notes, and the MIT license. No scripts or API connections are required. You need an AI agent that supports SKILL.md.

The demo below uses a synthetic sentence from the project's published evaluation set. Results will vary with the model and input. Check edited text before using it, especially for a resume or other factual document.
