nikolaeu/numi — reverse-engineered prompt

Build me a beautiful desktop calculator called Numi that works like a smart notepad. I want to type normal sentences instead of calculator buttons, and have it instantly show the answer as I type.

It should understand things like “20 inches in cm”, “$20 in euro with 5 percent discount”, simple math, percentages, unit conversions, currency conversions, and dates like “today plus 2 weeks”. Make the interface clean and pleasant, focused on typing and reading results quickly.

Please also include a simple terminal version so I can run something like numi with a quoted question and get the answer back. If possible, make the desktop app buildable for macOS, Windows, and Linux, but prioritize getting the core calculator experience working well first.

Keep the code organized so extensions or plugins could be added later. Look up current docs online if you need to.
