Harshpreet Singh (@harshpreet931) fed Claude Opus 5.5 his entire computer networks notebook, 120 handwritten pages, and walked away. About 60 minutes later it handed back a working font of his own handwriting. The demo video opens on plain ruled notebook paper, then shows the process that turns scanned scribbles into typeable glyphs. The whole run cost $13.68 at API prices, which is wild for a personalized typeface that normally takes hours of manual tracing. The post pulled over 460k views, and the thread walks through exactly how Opus did it.

  • 120 handwritten pages in, a usable personal font out
  • About 60 minutes of agent work for $13.68 at API prices
  • Step-by-step thread shows how the model extracted and built the glyphs
