I'm trying to assemble a list of programs and online services which use (a subset of) TeX's mathematical syntax without being or requiring a classic TeX installation. What I already have on my list:
- There are online services like Overleaf (merged with ShareLaTeX), Papeeria, and Authorea which offer collaborative editing of documents in the browser and either work like a full offline LaTeX distribution or support some mixture of Markdown and TeX syntax. Did I miss any?
- There's a LaTeX extension for Google Docs.
- I can't check because I don't have Microsoft Word, but apparently it understands TeX syntax.
- MathJax is in turn used by several Stack Exchange sites.
- The learning management system Moodle can be configured to support TeX-style formulas.
- Jupyter notebooks can display math using MathJax.
- The computer algebra system Mathematica "understands" TeX syntax to a certain extent.
- The Möbius courseware system (formerly Maple TA) seems to understand TeX syntax.
Are there any mistakes in this list? What else is out there? I'd rather not count software like IguanaTex for Microsoft PowerPoint as you need to have a TeX distribution installed to use it.
