Numara is a notepad-style calculator that combines freeform writing with real-time mathematical evaluation. Instead of using conventional calculator buttons, users type expressions directly into a text editor. Results appear automatically and update whenever calculations are modified. Notes and mathematical expressions can be combined in the same workspace for convenient problem-solving. Powered by Math.js, the application supports scientific functions, logarithms, trigonometry, statistics, and mathematical constants. It also handles percentages, physical units, and conversions between compatible measurements. Currency symbols can be used within supported calculations. Built-in function plotting helps visualize mathematical relationships and experiment with equations. Numara is available as an Electron desktop application and through a web interface.
