Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. It's 100% free, no registration required.

Do you know about some tools which can be used for online chat about mathematics? In particular, I am interested in software which would be able to render LaTeX formulas. (Since LaTeX is probably the fastest possibility to type mathematics.)

Have you tried some of them? What are their advantages and drawbacks?

NOTE 1: In this question I am asking only about solutions how to type mathematics in chat, not about possibility to use video and sound. (For the purposes of this question, assume that only keyboard, mouse and display are plugged to your computer.)

NOTE 2: I will post some possibilities I am aware of in the answers. But I would be grateful if someone who tried these applications could expand these answers a little more.

Theoretically it might be possible to make your LaTeX-code into pictures and - if the chat client enables this - paste them into chat. It seems that there are many possibilities how to do this, e.g. this online equation editor. But this solution is not so neat and much slower than typing LaTeX code directly into the chat. (I occasionally used such approach to get mathematical formulas into emails.) –  Martin Sleziak Nov 12 '11 at 15:43

GmailTeX if you use gmail –  leo Nov 12 '11 at 19:20
    
"Since LaTeX is probably the fastest possibility to type mathematics" Have you seen ASCIIMathML? –  Mk12 Oct 31 '13 at 23:14

Mathim - online chat with the possibility to use of LaTeX syntax (the first result that google returned for latex online chat or latex online chat math)

http://mathim.com

Screenshot from my short experiment with this tool:

mathim

Mathim was also discussed here:

It is possible to copy the text of session (simply by selecting it) and put it into a TeX file.

If some of you have worked with mathim and has some practical experience, I would be glad to know: Is there a possibility to save the text from the session in some way? –  Martin Sleziak Nov 12 '11 at 15:37
    
The problem with copying the text of session is solved now. (Before, when I tried to copy the text, the dollars where missing.) physicsforums.com/showthread.php?p=3860528 –  Martin Sleziak Apr 11 '12 at 17:36
    
I've noticed that MathIM has some problems with range in which fonts are valid. E.g. if you write $(2\mathbb N+1)\cup 2\mathbb N$ then the blackboard font is used for the whole text starting from N. You have to write $(2{\mathbb N}+1)\cup 2{\mathbb N}$ instead. Screenshot. –  Martin Sleziak May 22 '12 at 15:53

In the Mathematics chat, we often use the codecogs.com $\LaTeX$ Equation Editor: http://latex.codecogs.com/gif.latex?\sum_{k=1}^\infty\frac{1}{k^2}=\frac{\pi^2}{6} yields

\sum_{k=1}^\infty\frac{1}{k^2}=\frac{\pi^2}{6}

You have to replace spaces with %20 since spaces are not allowed in URLs (actually, it is probably best to escape all reserved characters in URLs, but other than spaces, most characters seem to be passed through by a number of common browsers).

EDIT: This project seems to be abandoned. (At least the website does not work anymore.) If anyone has the knowledge that it has been moved to another location, please, edit this post with updated information.

TeXChat is a chat which uses Mathjax for rendering math.

I've learned about it from the website MathJax in Use.

Here's a screenshot:

You can copy a source of an individual message by hovering above it and selecting the text.

I wasn't able to figure out how the source of the whole session can be copied. I you find out, please, let me know. (And maybe add this to the answer.) –  Martin Sleziak May 29 '12 at 8:32

I asked the author about that several months ago and had not received a response. –  Willie Wong May 29 '12 at 11:53
    
According to this it seems that he was planning to do this. (Hopefully, he still is.) –  Martin Sleziak May 29 '12 at 14:38

There are scripts written by Valery Alexeev.

They were mentioned in this answer: http://physics.stackexchange.com/questions/7809/online-physics-collaboration-tools/7811#7811

GmailTeX was mentioned in leo's comment. There is also GmailChatTeX.


This Firefox add-on http://thewe.net/tex/ seems to be similar.

Again, any comment by someone who actually tried some of these would be great. –  Martin Sleziak Nov 12 '11 at 22:00
