## What is Geulbut?

Geulbut is the keyboard buddy right by your words.
With mascot Bomi, everyday Korean typing becomes a little more fun and easy.

■ Wear your favorite theme
Pick from 7 preset themes or build your own with a color picker — all with live preview.

■ Gestures at your fingertips
· Swipe left/right to move the cursor
· Swipe on backspace to delete a word / undo delete
· Swipe up/down to toggle the number row
· Long-press for alternate characters and key repeat

■ Four Korean layouts
Dubeolsik, Cheonjiin, Naratgeul, and SKY — with natural Hangul composition.

■ AI translation right in the keyboard (Premium)
Translate what you're typing without leaving the keyboard, and drop it in with a casual, polite, or formal tone.
