Parsify

Parsify is a notepad‑style calculator that evaluates expressions in real time, showing results alongside the input. It supports advanced mathematical operations, variable definitions, and a wide range of built‑in units for length, mass, volume, temperature and more, with the ability to add custom units. Currency conversion covers over two hundred fiat and cryptocurrency rates that refresh hourly, while percentages, calendar calculations, and time‑zone queries can be expressed in natural language.

The application is designed for extensibility: users can create and share plugins to add new functionality, and the interface allows customization of fonts, text, and background colors to suit personal preferences. It runs on macOS, Windows, and Linux, with a free tier limited to five lines and a paid tier that unlocks unlimited lines, custom units, and full plugin support.

Privacy‑focused development means calculations are performed locally, and the UI is available in multiple languages, with community contributions encouraged for further translation.
