    We had this in the early 1990&#x27;s, it was called Mathematica [0]<p>[0] - <a href="https:&#x2F;&#x2F;writings.stephenwolfram.com&#x2F;2013&#x2F;06&#x2F;there-was-a-time-before-mathematica&#x2F;" rel="nofollow">https:&#x2F;&#x2F;writings.stephenwolfram.com&#x2F;2013&#x2F;06&#x2F;there-was-a-time...</a>

      It was eye-wateringly expensive and required a high-end system, though. It was good, and I liked it too, but it&#x27;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&#x27;t.

    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:<p><a href="https:&#x2F;&#x2F;www.inftyproject.org&#x2F;en&#x2F;software.html" rel="nofollow">https:&#x2F;&#x2F;www.inftyproject.org&#x2F;en&#x2F;software.html</a><p>(I used to use the math input palette w&#x2F; a Wacom ArtZ on my NeXT Cube for transcribing math documents in college)

    This is pretty cool, I have a long running hobby project to make something similar in the terminal. <a href="https:&#x2F;&#x2F;github.com&#x2F;ShaneMarusczak&#x2F;rm-repl" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ShaneMarusczak&#x2F;rm-repl</a>

    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&#x27;t even manage that.

    If your in the Apple ecosystem, Soulver is a similar app to this that is really great.<p>I still like it better than the math built into notes for anything beyond basics.

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

    I&#x27;ve been using notepadcalculator.com for years and it&#x27;s been great

    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()
