FontCrafter: Turn your handwriting into a real font

Original Article ↗ Hacker News Discussion ↗

Overall reception

  • Many find the idea nostalgic and fun: turning one’s handwriting (or others’, like historical samples or kids’ handwriting) into a font is seen as both playful and sentimental.
  • Several note they’ve used similar tools in the past and like having fonts that preserve family members’ writing or their own from years ago.
  • Some say their handwriting is too ugly or illegible, joking it would act as “encryption” or that the world doesn’t need to see it.

Privacy & implementation

  • The “no account, no server, 100% in-browser” design is widely praised as rare and positive.
  • A few skeptics suggest testing offline (disconnecting from the network) to verify everything runs locally.
  • The tool uses opentype.js in-browser to generate fonts.

Cursive and handwriting culture

  • Major limitation: unclear or absent support for cursive / connected scripts; several people primarily write cursive and feel excluded.
  • Debate emerges over where cursive is still taught or used (US, UK, France, Germany, Russia, etc.) and whether the issue is cultural vs. generational.
  • Some describe very stylized, variable personal handwriting that would require multiple fonts and randomization to feel authentic.

Accuracy, UX, and bugs

  • Experiences vary sharply:
    • Some report it “just works” and feels impressive, especially when scanning with phone apps and simple cleanup.
    • Others encounter serious issues: misdetected alignment, corner markers read as glyphs, letters shifted vertically, broken strokes after thresholding.
  • The template has configurable rows for upper/lowercase, but some find the constraints (only certain row combinations) limiting.
  • Pen thickness and scan resolution matter; thinner pens and certain DPIs produce broken or misaligned glyphs.
  • Several suggest better registration (more distinct marks, manual mark selection) and pre-processing (dilate filters) to improve detection.

Market context & alternatives

  • Commenters recall earlier web tools that were bought and folded into a single commercial service with subscription limits; this project is welcomed as independent, non-server-based competition.
  • Some point out related approaches: drawing directly on mobile, encoding handwriting as JS paths, or using OCR/LLM pipelines to synthesize fonts.
