Numi is a calculator app for macOS, Linux, and Windows that interprets natural language expressions to perform calculations and conversions.
The tool solves the problem of tedious calculator interfaces by accepting human-readable input like "$20 in euro - 5% discount" or "today + 2 weeks" and returning instant results. It parses natural language expressions into computations, supporting currency conversion, date arithmetic, unit conversion, and basic mathematical operations without requiring formal syntax.
Numi suits developers and power users who want faster calculation workflows than traditional calculator applications. The desktop version for macOS offers the full feature set, while a terminal version provides command-line access with most features implemented. An Alfred extension integrates the tool into Alfred workflows on macOS. The terminal version does not yet support timezone conversion, CSS styling, variables, or plugins, though other core functionality like localization and date handling is available. Users should note that the desktop application is the primary interface with the most complete feature support.
The project maintains active development across multiple platforms with regular updates to both the desktop and command-line interfaces. The tool is distributed through multiple channels including direct downloads, GitHub releases, Homebrew, and as an Alfred workflow, indicating sustained effort to reach different user preferences. The README explicitly documents unimplemented features in the terminal version, showing transparent communication about capability gaps between different interfaces.
