what one tap does
Korean has 11,172 syllables. Write 39 — the rest is one tap.
Writing them all by hand is nearly impossible. TappyType's AI learns your style from the few you write and draws the rest to match.

How my handwriting became a real font
Do you like typography?
Since I was a little girl, I’ve loved typography. Sometimes I dreamed of turning my handwriting into a font.
Today, thanks to AI, we can do almost anything in the digital world. For my dream of making my own font, I decided to build an iPad app that easily creates character image files.
However, there’s still a challenge because of the unique properties of the Korean character 한글. I need to write out each character for the 11,172 possible character combinations (at least 2350). If not, you will see clumsy characters. Neither the Apple Pencil nor NanoBanana can solve this problem.
I set aside my ideas and searched the internet until I found six-year-old open-source code (quite old in the AI field). I immediately started experimenting to speed up the process. In the end, my dream became a reality.
Because I want to share this experience with others, I designed, coded, and tested it myself. Now, I have a team member who will rebuild and upgrade the AI model. So, I started to prepare the App Store documents and do some PR! (yeah, that’s what this is)
From now on, I will share my story about the first launch and my very first app. I hope it works, but even if it doesn’t, my enthusiasm and heartfelt thoughts or actions for this first attempt are still worth recording. It’s also a personal test to see if I want to be an entrepreneur.

Computer vision is what got me into ML; 3+ years of production systems later — tabular classifiers, generative AI, LLM pipelines — I still care most about what a model does for the person using it. Here, that's something genuinely fun: teaching a model to read your 손글씨 and turn it into a font that's actually yours.
