    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:

                      https://www.inftyproject.org/en/software.html

                      (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()
