Annotation Mono is a lovingly crafted handwriting-style monospace font.
Annotation Mono is an idealized handwriting; using letter forms inspired by monospace bitmap fonts, legibility is maximized while retaining a hand-written character.
Its variable weights make Annotation Mono ideal for a wide variety of use cases other than code, including labels and headings. Given its hand-written look, you could even use it for comic lettering if you want.
