Numi

Numi combines a calculator with a text‑based interface, letting users type mathematical expressions alongside natural language. It supports arithmetic, unit conversions, currency rates, time‑zone calculations, and numeral system transformations, all within a single input field. Results are displayed instantly, and users can define variables for reuse throughout a session.

The application runs on macOS, Windows, and Linux, offering a consistent experience across desktop environments. It includes features such as export of calculations, a notification widget, and multilingual support for several languages. A command‑line version is also available for users who prefer terminal interaction.

Designed for individuals who need quick numeric and conversion tasks—students, engineers, finance professionals, and anyone handling everyday calculations—Numi provides a straightforward, text‑centric workflow without requiring separate tools for different types of math.
