### Latest reviews

• (2021-01-29) Aliaksei Semchankau: Very convenient so far
• (2021-01-27) Yuval Heller: Amazing extension! Makes typing formulas in an email much easier.
• (2020-12-07) Krister Swenson: So darn nice.
• (2020-08-23) Marcelo Videa Vargas: It saves a lot of time. Before I had to import compiled LaTeX as images. Excellent extension! Thanks.
• (2020-07-19) Atharva Pangarkar: This is an amazing tool to use with no hassles at all. Loved it and would recommend it to my friends who type a lot of math. Though I have a question for the creator of this extension: Please explain why does this extension need to have a look at ALL of our inbox data? If the answer is too technical, explain in layman terms.
• (2020-04-15) Kherian Gracher: Uma excelente forma para utilizar a linguagem LaTeX em seus e-mails.
• (2020-04-01) Caspar Gutsche: It works great, exactly what I was searching for. It even integrates nicely into the Gmail UI, thank you.
• (2020-03-31) Sunil Koswatta: This is great!. However, I found at least one inline command is not rendering. It is the \nobreakdash command. Find the $\lim\limits_{(x,y)\to(0,0)}\frac{x-y}{x^2+y^2}$ along the $x$-\nobreakdash axis.
• (2019-10-16) Matt Raymond: I love this. It makes it super easy to ask my Calc professor questions.
• (2019-09-28) Lizhi Guo: I don't know if it is because of me. The extension seems to take a while to work. For longer expressions, it basically doesn't.
• (2019-09-10) Roberto García: Excelente, me ha funcionado de maravilla para correos cortos y largos.
• (2019-09-09) Raul Duarte Gonzalez: very useful for communicating equations. a must-have for grad students in quantitative fields
• (2019-09-02) Carlos Antonio Pinzón: Very nice and useful! The only annoying issue is that you can not copy-paste formatted formulas. Whenever I try to, the formula disappears and all other formulas in the message disappear as well.
• (2019-08-13) Assaf Patir: Very simple, very useful.
• (2019-07-07) Zhe Su: How to write a matrix using this extension? For example $$\begin{pmatrix} \alpha & \beta \\ \gamma & \delta \end{pmatrix}$$, I aways get "formula does not parse".
• (2018-11-09) Robert Kalinowski: Rewelacja. Wszelkie wzory wyglądają ślicznie (tak to w TeX-u). Dwa tryby, pełna obsługa (obrazek) i uproszczona, korzystająca z HTML. Polecam.
• (2018-09-16) Piotr Hajlasz: I use it almost every day and it forks great for simple formulas. Unfortunately it is not possible to write very complicated expressions. Moreover sometimes it simply does not work. As I understand it uses some external server which sometimes does not work. You write formula, you send it out and the formula disappears, so check carefully the outcome what you send. I rank it 5 stars because it is really extremely useful and I am not aware of any other TeX extension for Gmail.
• (2018-05-22) 路明非: The Mouse pointer will offset its correct position when I use the Tex,. My operating system is Win 10, Chrome version is 66.0.3359.181 (latest version)
• (2018-05-19) Nat Mayer: Can't believe I haven't been using this for years. Must have extension for anyone typing equations. I ran into a few issues in my first few emails (trouble with matrix environments, copy-pasted code not compiling), but everything had answers already given in the support section (repectively, change option from Wordpress to Codecogs, remove HTML formatting).
• (2018-05-18) David Gasul: Wow! Finally an extension I can enter math and superscripts / subscripts in gmail!
• (2018-03-10) TheLie Llama: Seems to work great, though I am unable to get stuff like \mathbb(R) or \mathcal(U) to work. Would be really helpful to add support to some of these basic fonts.
• (2018-03-06) Ruben Tobar Quiroz: Tengo problemas al intentar poner matrices. Por ejemplo $$\begin{matrix} a & b \\ c & d \end{matrix}$$ me arroja error
• (2018-02-28) Mark Colas: It really doesn't work consistently enough to be useful.
• (2018-02-07) Mario González: Funciona bien para ecuaciónes cortas, pero en otras más largas falla en convertir...
• (2018-01-21) Faseeh Muhammad: This is really helpful. Can i use environments like {align} environment here?
• (2017-12-04) Wesley Neill: Sometimes it works. Sometimes it doesn't.
• (2017-10-30) Fabricio Morais: Não funciona
• (2017-10-18) Enrique Castañeda Alvarado: excelente aplicación
• (2017-09-23) Konstantinos Anagnostopoulos: Great app, can't find anything better available. Manages complicated formulas fine and has the option of simple formatting for simple formulas that uses plain html. This is important, since you do not depend in that case on a server to render the image that displays the formula. I wish this would have been possible also for the Rich Math formatting, i.e. that the images of the formula were physically embedded in the email message for formulas that we would be sure they would last forever. As it, when the server is down or if it disappears, it will be hard to read it (although not impossible since the formula is embedded in LaTeX form in the message as alt info). The new version adds the impressive option to TeX a message sent to you containing real LaTeX or pseudo latex that we usually use between informal communications. In the latter case the app makes very good guesses and the message appears in a very legible format! Very helpful, thank you! I have used it extensively on Google Chrome and Firefox on Linux systems. Great work, thank you!
• (2017-09-14) Dr Mohammad El-Nesr: It is important to know that the extension works only if you typed LaTeX code, then press the TeX button, it will replaces your code by pictures of equation If you don't know to write LaTeX, then use this online tool https://www.codecogs.com/latex/eqneditor.php or any similar one, then copy the code it provides, paste it to your email, then press TeX button.
• (2017-08-09) Salman Habib: Excellent
• (2017-08-03) Jess Riedel: The equations generated by this plugin look great even for people who don't have gmail or the plugin, and the interface is snappy and sensible. Most importantly, you don't have to completely re-type an expression if you make a mistake. Just click on it to covert it back to TeX code. Below are some critiques, but on the whole I find this plugin invaluable and highly recommend it. The server used to generate the high quality images (F8) has occasionally gone down, or become very unreliable, at times in the past. I use this plugin daily, and it only happened a handful of time in the last 6 months. My understanding is that this is not controlled by the developer of the plugin, but it would be nice if there was some warning. ("F8 Image generation not currently available.") Furthermore, depending on where in the request the server crapped out, it was possible for your latex code to replaced with an empty placeholder, causing the code to be lost (as opposed to recoverable, like it normally is, by clicking on the equation image), which is very frustrating. In the past, the plugin would completely stop functioning randomly from time to time. (I confirmed this with at least one other user down the hall.) It could only be fixed by reloading the Gmail tab in Chrome, but this was very inconvenient in the middle of a long email. However, this bug appears to be fixed. Finally, the simple unicode conversion (F9) needs some tweaking. It incorrectly puts everything in italics, rather than just the roman characters. Greek letters, and especially things like parentheses, shouldn't be italicized.

### Latest issues

• (2020-10-01, v:6.7.2) Huck Bennett: Basic parsing issues
For me, both of the expressions $l_p$ and $\ell_p$ have issues parsing. The former doesn't parse at all (it results in an error), and the latter gets inserted at least a line below the current line.
• (2020-09-19, v:6.7.2) Dave Doty: remove two invisible whitespace symbols after expression in simple mode
When creating a LaTeX expression in simple mode, two invisible whitespace symbols are inserted at the end of the expression. It would simplify editing post-pressing-F9 to strip these symbols out automatically.
• (2020-09-19, v:6.7.2) Dave Doty: italicize only variable names
It would be great it one could specify that only variable names are italicized in simple math. The default "Font for Simple math, composing an email" is font-style:italic; which leads to all symbols italicized, including operators such as { } ⊆ and numeric literals such as 1 2 3. One can remove "font-style:italic;" to unitalicize everything, but it's nice if variables only remain italicized. For example for a_1 = b, the "a" and "b" should be italicized, but not the "1" or the "=". Not sure how straightforward that would be to implement. Even a simple heuristic such as "italicize Roman and Greek letters, and nothing else" would be really nice.
• (2020-06-24, v:6.7.1) José Gustavo Coelho: Expression will not parse
This won't parse, no matter if i rewrite it close chrome and open it again. $\alpha = \alpha_0 + \alpha_1 \tau$ But this will $\alpha = \alpha_{0} + \alpha_{1} \tau$ The former parses without problem in regular latex. So i guess there is a problem with indexes in greek letters?
• (2020-06-21, v:6.7.1) Damien Sutevski: siunitx
Possible to get this syntax added too? http://tug.ctan.org/macros/latex/exptl/siunitx/siunitx.pdf : ) This seems like it is going to be sooo useful.
• (2020-05-01, v:6.7.1) Dipendra Prasad: Tex for Gmail
Here is what I was typing, but some get texed but some others dont. Can you say why, and what I need to do? (You do not see what is getting texed but you do see what is not getting texed). Sincerely, Dipendra Prasad I am not certain if I can answer further, but let me try how much I can go.  First, note that the 5-dim'l rep'n of PSL(2,11) in fact lands inside ￼, and the two representations arise via the Galois action  ￼ over  ${\mathbb​ ​​Z}$. In fact: the maps  $PSL(2,11) \rightarrow SL(5, {\mathbb Z}(\sqrt{-11})) \rightarrow SL(10, {\mathbb Z})$  gives rise to ￼. Therefore if B is an abelian surface on which ${\mathbb Z}(\sqrt{-11}))$ acts, then on ￼, ￼ matrices over ${\mathbb Z}(\sqrt{-11}))$ will act, and hence you will get a 10 dim'l abelian variety with an action of  PSL(2,11). How does this action look like on the tangent space of A? Since ￼,

Hi, I can't seem to do multiline equations here
• (2020-03-28, v:6.6.12) kevin roberge: matrices?
Thanks for this extension, it's wonderful. As a math teacher during this pandemic it's nice to be able to type more readable answers to student's questions during this period of Distance Learning. I noticed and appreciate that I can create nx1 matrices, any plans on nxm? My desire is something like \begin{bmatrix}1&2\\3&4\end{bmatrix} to render. Not a complaint, just a wish. In the meantime (in case someone else is reading this, you can use a site like latex2png.com and render such a matrix and copy the image (right click) and paste inline into your Gmail. Thanks, Kevin
• (2020-03-04, v:6.6.12) Gina Polo: Tex button, gmail.
Hello, I installed the extension Tex for Gmail, but I do not see the TEX button on gmail. I tried reinstalling and restarting my computer, but this was unsuccessful. I am using a OS X. Thank you very much in advance,
• (2020-01-27, v:6.6.12) David Gillcrist: Does not seem to work
I can't get any of the formulae to actually convert from TeX to an image. I have tried clearing my cache, I don't have either of the repositories blocked by my browser. I have tired both Codecogs and Wordpress. I have not been trying it with complex expressions, just simple ones such as: $\frac{a}{b}$. How long does it take to convert? Is there a video tutorial somewhere so I can actually see the procedure conducted to create formulae in an email?
• (2020-01-18, v:6.6.12) José Gustavo Coelho: ams packages commands such as \mathbb{F}?
I have latex installed locally with some packages, but i guess the extension uses its own implementation of TeX. I noticed it can't use amssymb commands like \mathbb{F}, but \mathbb{Z} works fine. What is up with that?
• (2019-12-04, v:6.6.12) Michał Margos: Not any help
Who do I know what to write? There's no any help or hints, just a button.
• (2019-09-18, v:6.6.12) Subhadeep Ranjan Dev: Not working
I had no problem in using this extension. But recently I do not see the tex button on gmail anymore. I am tried reinstalling the extension, but this was of no help. Kindly advise.
• (2019-07-07, v:6.6.12) Michaël Cadilhac: Editing text mid-line in continuous mode puts the cursor at the eol
Please have a look at the following screencap: https://michael.cadilhac.name/public/tfg.gif When the rendering is done, the cursor jumps to the end of the line.
• (2019-07-07, v:6.6.12) Michaël Cadilhac: Backspace to get back in the formula?
Splendid extension, a life saver, and all my colleagues are flabbergasted. Quick suggestion, if it's technically possible: I like the continuous rich mode, but when editing, clicking on the formula AND answering the confirmation is quite cumbersome. What about opening up the formula if I hit backspace on it? That seems like the natural thing to have, rather than deleting the whole formula. If that's impossible, can you consider adding an option for not having the popup window asking if I want to edit the formula? Cheers, and thanks again! (Where's your tip jar?)
• (2019-06-17, v:6.6.12) Matt Lewandowski: equations disappearing after send
Within the last few days, when I compile my email using "rich math," i can see the Latex in my email window, but when I send it, it does not show for the recipient. The problem happens even when I send the email to myself. There is no problem with "simple math," though. Any thoughts? Thank you!
• (2019-05-12, v:6.6.12) Tae-hwan Rhee: Cannot locate the help file...
I just installed this Chrome extension, but I cannot start using it. When I wrote down something like " Y=\alpha+\beta_{1}X^2" in my Gmail, highlighted (selected) this part, and clicked the LaTeX button and tried any of the four options there, nothing happened. And I cannot locate the 'help file' mentioned here... where is it? Is there any 'quick start guide'? Thanks!
• (2019-03-28, v:6.6.12) Trevor Campbell: Gmail resizing math
When I render math, gmail automatically resizes the images to "small" (rather than "original"). The choice to resize back to original only comes up when you click the image, but the TeX for Gmail window pops up (asking to replace the image with tex), blocking me from choosing "original". So now all my math is super tiny and unreadable. Help?
• (2019-02-14, v:6.6.12) Taylor Copeland: Excessive Memory Usage
On Ubuntu 18.10, I saw in the Chrome task manager that the extension was using around 1.6GB of memory, even when Gmail was not open.

It will be great if you make similar extension / addon for mozilla firefox also.
• (2018-12-05, v:6.6.12) Ayrat Khalimov: TeX the selected text only
Is it possible to TeX only the selected text? That is, if I press the TeX button, then the plugin converts the TeX only in the selected text? (if nothing is selected, then convert everything) (Why: I want to be sure that only text in my reply is converted and not the text of the sender mail) Thanks!
• (2018-09-27, v:6.6.12) Andrew Booker: stopped working in the new gmail
I am a long-time user of the extension and it was working as recently as two weeks ago, but now I am unable to process any TeX in gmail. F8 has no effect and the TeX icon next to Send is missing.
