Move any slider and the text changes live, drawn from the exact rules the font file is built from. Save keeps a draft in this browser (or the connected Claude host). Download JSON gives you settings for the Python builder. Browser drafts stay on this device and site; saving does not rebuild font files.

Languages

Phase 4 adds complete Latin Extended-A, common Slavic Cyrillic, monotonic Greek and full Vietnamese. Rows include language-specific forms, accents and real italics. The modern scope is recorded in languages.json; native-reader and device checks remain to do.

Type anything

Put words between stars for italic, like *this*.

Comments with custom emojis (demo)

Type : and a few letters (try :cul or :fire) or use the emoji button. The comment saves plain text like :cultivator:, and the app swaps it for the image when showing it. Comments here are just for trying it out and aren’t saved.
