I've been using this #tool for years, but I think more people should know about it.

It makes it easy to find a #LaTeX symbol in a few seconds!

Detexify LaTeX handwritten symbol recognition

An approach to simplify finding LaTeX symbols.

@solalnathan There was also https://github.com/MartinThoma/write-math (that used to be hosted at http://write-math.com/ ) which was *very* good but seems to be discontinued, unfortunately.

@clementaubert looks nice. If it's good I will probably host one myself, it's a shame the website is offline...
@solalnathan Start from this fork ( https://github.com/TrellixVulnTeam/write-math_SIIL ), maybe? It was *really* nice the way I remember it, better than detexify (at the time).
