About geulssi
geulssi helps adults who speak English learn to write Korean letters (Hangul) by hand. The name means "handwriting" in Korean (글씨).
How it teaches
- Each letter on the Hangul chart shows its strokes one at a time, in the order of the Korean textbook for adult learners (EPS-TOPIK standard textbook). The 24 basic letters were also checked against the Korean primary-school textbook.
- You watch it, trace it, then write it from memory — first each letter, then whole syllable blocks (안 = ㅇ + ㅏ + ㄴ), words and your name.
- Your writing is checked stroke by stroke: how many strokes, their shape and where they go. If you write a stroke in another order or direction than the textbook, you get a short note. Finish a block and you get a stamp.
What is different
- Your writing is actually checked, not just drawn over a picture.
- On My name in Korean you can turn your English name into Korean, practise writing it and share a stamp card.
- There are no accounts and no ads. See Privacy for what is stored.
