Kuaishou's video AI that competes directly with Sora. When Korean users type 클링 (keul-ling) on a QWERTY keyboard still set to English, the keys produce zmffld. This page explains the mapping and how to make the most of Kling AI 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 클링 is typed as these keys:
Put together: 클링 typed in English mode spells zmffld. Korean users searching for Kling AI 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 Kling AI results.
Kling AI is a text-to-video and image-to-video model from Kuaishou, the Chinese short-video company behind Kwai. Released in 2024, Kling quickly gained attention for producing fluid, physics-aware video clips at a quality level comparable to OpenAI's Sora but with a more generous free tier. It generates up to two minutes of video at 1080p.
Kling became popular in Korea partly because Kuaishou's Kwai app already had a Korean user base, and partly because Kling's free daily credits made it accessible without a subscription. Korean YouTubers and TikTok creators use it to generate AI B-roll, and K-pop fan video makers use the image-to-video feature to animate static fanart into short clips.
