TeXr

Texr is the definitive solution for typing math inline. No compile time, no steep learning curve, and no syntax shenanigans. Texr allows you to type math and paste it anywhere, with no additional software required to view it for any device that supports Unicode; want to post DeMorgan's Theorem to GroupMe? No problem, type it up in Texr, paste it into Groupme, and hit send. Anyone can read it, whether they're on their phone or the web client, with or without the extension installed. To check whether or not your device supports Unicode, if you can read this: ¬(A ∨ B) = ¬A ∧ ¬B, then you can utilize all of Texr's features. Now, suppose you are taking math classes, have an online study group, and want to ask a question. Existing options include LaTeX, and writing out the equation on a piece of paper and taking a picture. The main problem with LaTeX is that it takes a long time to learn, is time intensive to use, and most likely isn't worth the time to learn if you choose not to pursue math research. On the other hand, taking a picture is easy and not quite time consuming, but if your handwriting is messy, or if your group messaging app doesn't support uploading images, then it's not much of a solution at all. TeXr solves these problems by essentially being a simpler, realtime-compiled LaTeX. TeXr uses a smaller symbol set, and can therefore be more lightweight and better-suited for students or others who just want to type and communicate math quickly. There are only eight commands that you need to know to use TeXr at peak efficiency: 1. Type \ to begin inputting a command. 2. You can click the suggestions that appear as you type a symbol to autocomplete. 3. The glossary shows every available symbol, categorized by field of math. 4. Clicking a term in the glossary inserts it automatically at the end of the existing text. 5. ^ controls superscript. You can type any number 0-9, +, -, =, (, ), n, and o as valid characters. 6. Superscript parses and ends when you type a space, or _. 7. _ controls subscript. You can type any number 0-9, +, -, =, (, and ). 8. Subscript parses and ends when you type a space, or ^. Texr is programmed and maintained by Stephen Nurushev, Jack Murphy, Michael Mattheakis, and Daniel Capodilupo from the University of Michigan.
