Comes in two variants. “Dialogue A, designed by Cosimo Lorenzo Pancini, has slightly larger proportions, square punctuation and a more evident brutalist approach in terminals and serifs. Dialogue B, designed by Andrea Tartarelli, features a subtly more calligraphic design, with tighter proportions and different design details.” [Zetafonts] There are also variable fonts (upright and italic) that cover both variants, with axes for style and weight.

Dialogue ME (Middle East) adds support for Hebrew (design by Oded Ezer) and Arabic (consulting by Murad Alshawareb). Version 1.45 was released in 2025.
