I've been using "detexify" since grad school which was a decade ago or so.

It's by far the best tool for LaTeX I've ever used. You just have to draw the symbol and it uses pattern recognition algorithms to suggest the closest LaTeX keyword.

Yep, I've used it. It's amazing! I'm also adding a link to it on my page, so people can find symbols they don't yet know how to describe with text

I felt that 'type and hit enter to copy' would be faster for my workflow, which is why I built this :D

Very neat. Thank you!

ah, this is indeed quite neat. thanks for sharing.
