NoteCalc is a hybrid note-taking and calculation tool that merges a text editor with a powerful inline calculator, allowing users to write structured notes while performing real-time computations alongside them. The interface is split into two synchronized panels where the left side contains editable text and the right side automatically displays computed results for each line, creating a seamless workflow between documentation and calculation. Designed as a web-based alternative to tools like Soulver, it emphasizes clarity and context by keeping formulas and results visually aligned. The system supports advanced mathematical operations, including matrices, units, percentages, and custom functions, making it suitable for both everyday calculations and more technical use cases. It also features intelligent parsing, autocompletion, and variable referencing, allowing users to build complex calculations incrementally across multiple lines.

Features

  • Real-time inline calculation within a text-based note editor
  • Support for variables, references, and user-defined functions
  • Matrix operations and advanced mathematical expressions
  • Unit handling and conversions within calculations
  • Autocompletion and intelligent expression parsing
  • WebAssembly-based performance for browser execution
