What problem does it solve? AI-generated text carries recognizable patterns — formulaic connectors, inflated significance, cliché openers, and template structures — that make it read as machine-written. This Skill post-edits (윤문) such text to read as human-authored without changing what it says, across Korean, English, Japanese, and Chinese. ## Core Features & Use Cases - Multilingual tell catalogues: Per-language detection categories for prose and marketing copy, each with severity tiers (S1/S2/S3) and before/after rewrite examples in the target language. - Meaning-preservation machinery: An Invariant Ledger anchors facts, identifiers, numbers, and caveats before editing; a Delta Audit verifies survival after editing and forces rollback on any drift. - Dual grading and guardrails: Prose mode grades A/B/C/D with 30%/50% over-editing change-rate gates; copy mode replaces the change-rate guard with a fact-anchor preservation guard for headlines, CTAs, and landing pages. - Genre modules: Display-copy rules for landing pages and slide decks, plus a review-only QA-gate pipeline that detects formulaic copy and proposes fixes without auto-applying them. - Use Case: Paste an AI-drafted English blog post and receive a humanized version plus a change report listing the tell categories hit, the quality grade, and the estimated percent changed. ## Quick Start Humanize this AI-generated Korean marketing copy and report which tell categories were removed and the final quality grade.
