The GitHub release says Claude Code built it from one prompt in 1 hour and 6 minutes, with $13.68 in API costs.
The release includes Regular and Bold TTF files for desktop use, WOFF and WOFF2 files for the web, a CSS theme, a specimen page, and a 65-second making-of video. A jsDelivr stylesheet can load the web font. The fonts are under the SIL Open Font License 1.1.
Harshpreet Hand provides two or three rotating variants for each letter through the calt feature, a plain-r stylistic set, kerning, Latin letters, digits, punctuation, arrows, and Western European accents. The release does not establish that the same time, cost, or one-prompt process will reproduce another person's handwriting, nor does it detail any manual correction or evaluation procedure.
