About Kalcy

Kalcy is a modern Mac calculator that makes math feel like ordinary conversation. Simply type calculations in plain English, like "5 cm plus 1 meter" or "compound interest on 10k at 5%”, and Kalcy instantly turns your thoughts into answers. It combines the flexibility of a text editor with the power of a calculator, letting words and numbers work together naturally. When a prompt goes beyond Kalcy's built-in parser, AI automatically rewrites it into precise mathematical expressions, so you never have to think about syntax. Beyond calculations, Kalcy handles unit, currency, date, and time conversions on the fly. Whether it's "20 dollars in euros" or "today + 2 weeks", results appear instantly. With configurable global hotkeys, Kalcy is always just a keystroke away.
