Iris Gu (顾砚秋) — Founder & Type Designer, MoFont.

I am Iris Gu — 顾砚秋 in Chinese — and MoFont is the small studio I run from a writing desk in Hangzhou. I build the tool I wish had existed the year I hand-lettered 180 wedding invitations: a way for anyone, not just professionals with a typography degree and a research budget, to turn their own handwriting into a real OTF/TTF font.

What I work on

  • CJK type design. The Han script has a long tail of rare glyphs that breaks most "handwriting-to-font" services. Closing that gap — beautifully — is most of what MoFont does.
  • Generative models for handwriting. zi2zi, deepvecfont, LoRA fine-tunes, and the unglamorous post-processing (potrace, FontForge scripting) that turns a model output into a font file that actually opens in Microsoft Word.
  • Font engineering. OTF/TTF tooling, hinting, kerning, the FontForge Python API, and the quiet pain of importOutlines flipping the Y axis.
  • East Asian typography & visual culture. Why a Song-style serif feels different from a Ming-style one, and why a font cut from your own hand reads like your own voice.
  • Bespoke wedding stationery & paper craft. The thing that started all of this.

Why I built MoFont

The long version is in this post. The short version: I spent ninety hours hand-lettering envelopes for my own wedding, finished, and realised the only reason this was a romantic gesture and not a common one was that nobody had built the tool. So I spent a year building it.

MoFont's promise is small and specific. Upload thirty handwritten characters. Wait about an hour. Download a complete OTF and TTF covering 6,500+ Simplified Chinese, 7,000+ common Japanese, or 2,350+ common Korean glyphs. Use it for your diary, your love letters, your wedding invitations, your small-brand identity. No subscription. No watermark. No "upgrade to remove our branding from your font name." It is yours, because it is your hand.
