Korea's own AI platform, free and Korean-first. When Korean users type 뤼튼 (rwi-teun) on a QWERTY keyboard still set to English, the keys produce fnlxms. This page explains the mapping and how to make the most of Wrtn as a Korean user.
On the standard Korean 두벌식 (2-set) layout, typing while the input is still in English mode maps each Korean character to a specific QWERTY key. The Korean name 뤼튼 is typed as these keys:
Put together: 뤼튼 typed in English mode spells fnlxms. Korean users searching for Wrtn who forget to press the 한/영 key first land on this search term — and Google's intent matching now routes many of these searches to Wrtn results.
Wrtn (뤼튼) is a Korean AI service platform that provides access to multiple AI models — including GPT-4o, Claude, Gemini, and Wrtn's own models — through a single free interface. Unlike most global AI tools, Wrtn is built specifically for Korean users with Korean UX, Korean content templates, and deep integration with Korean writing conventions and business document formats.
Wrtn is one of the most widely used AI tools in Korea precisely because it is free, Korean-first, and gives access to premium models without individual subscriptions. Korean students use it for 자기소개서 writing, Korean office workers use it for 보고서 and email drafting, and Korean marketers use its template library for ad copy. Wrtn's 'Wrtn Studio' lets developers build AI-powered Korean apps on top of its infrastructure.
