We had this in the early 1990's, it was called Mathematica [0]

  It was eye-wateringly expensive and required a high-end system, though. It was good, and I liked it too, but it's not the same as being usable from pretty much anywhere for $0.

  Not just running right there and re-rendering in the browser you didn't.

    We got alone fine for decades without browsers.

Great tool. Reminds me of Instacalc, which has bee around forever.

This is pretty cool, I have a long running hobby project to make something similar in the terminal. https://github.com/ShaneMarusczak/rm-repl

I was using Apple Notes for some “math thinking” the other week. A killer feature for me would be an easy way to input various math Unicode characters (I was just copy and pasting them).

  There are various stylus-based tools which do that sort of thing:

  (I used to use the math input palette w/ a Wacom ArtZ on my NeXT Cube for transcribing math documents in college)

Pretty cool. It looks like it also uses local storage - so if you navigate away and come back (or just refresh the page) all of your expressions are still there. A lot of paid productivity apps that I use don't even manage that.

If your in the Apple ecosystem, Soulver is a similar app to this that is really great.

I still like it better than the math built into notes for anything beyond basics.

  $39?! I'll stick with qalc!

Pretty cool but handling large numbers is pretty limited: chokes on 171! Or 5^5^5.

Cool project. I wonder what benefits it has over using good old Desmos Calculator.

  It would be cool if it could be part of a text notebook. E.g. extended Mathjax syntax in Markdown that allows plot() or derive()

I've been using notepadcalculator.com for years and it's been great
