Numi

Numi is an innovative and sleek natural-language calculator application for macOS, Windows, and Linux. It completely rethinks the traditional calculator interface by blending the functions of a powerful calculator with a simple text editor or notepad.

It's designed to let users calculate complex expressions, conversions, and date/time differences using plain, conversational language.

Key Features of Numi

Numi's main appeal lies in its intuitive, text-based workflow:

Natural Language Processing

• Conversational Input: You can describe your calculation in simple phrases, and Numi interprets it instantly.

  • Examples: 20 in euro - 5% discount or 3 weeks from today

• Word Operators: You can use both symbols (+, *) and words (plus, times, of, subtract).

Contextual Conversions

Numi eliminates the need to look up conversion factors by handling them automatically in the text:

• Currency: Supports a huge list of currencies and cryptocurrencies with frequently updated rates. Example: $100 CAD to USD

• Units: Converts length, weight, area, volume, temperature, and data size. Example: 7 inches in cm

• Time Zones & Dates: Calculates time differences and converts between time zones. Example: 2:30 pm HKT in Berlin

Notepad-Style Calculation

• Multi-Line Calculations: You can perform and view multiple calculations simultaneously, line by line, maintaining a record of your work.

• Variables: Easily declare and reuse variables to simplify complex or multi-step calculations. Example: v = $20 then v * 7

• Totals: Use the sum or average tokens to automatically calculate the total or average of the results from the lines above.

• Comments and Headers: Use symbols like # for headers or // for comments to make your calculation notes readable and understandable.

Integration & Design

• Minimalist Design: Features a clean, distraction-free interface with a two-column format (input on the left, results aligned on the right).

• Alfred/Raycast Integration: Offers extensions for popular macOS launchers like Alfred and Raycast for quick, on-demand calculations.

• Customization: Supports basic CSS unit conversions (e.g., pt to px).

• Open Source: The core calculator engine is open source, and the desktop versions are available for purchase or via services like Setapp.
