• (2025-03-04) Konstantinos Anagnostopoulos: It is sad that the great app was turned off today by Google. It is unreplacable, as far as I know. If anyone has a suggestion, please let us know! Thank you! ==================================================== 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!

• (2022-07-20) Yang Liu: Amazing extension and exactly what I wanted for such a long time! One thing I would not have imagine is that the rendered inline TeX equations are horizontally ALIGNED with the rest of the text, which is a MAGIC solution to writing TeX commands in any mails. One suggestion to improve this TeX4Gmail solution for high-dpi (which is a wide-spreading trend, 2K on mobiles/PCs and 4K on desktops) is fetching images of 600% scale factor (from CodeCogs or WordExpress) and downscaling it correspondingly. I did it by customizing the downloaded extension and adding an additional option of "upscaling 600% and downsizing to fit the text". It's a pity that Gmail has not support SVG even in 2022, where almost all other browsers (web and clients) have supported as shown here https://www.caniemail.com/features/image-svg/. Otherwise, this extension could be easily adapted to support rendering SVG format of TeX for Gmail, which is the ultimate solution I am looking forward to.
• (2022-01-25) Manu Upadhyay: Renders the equations beautifully!
• (2021-11-25) Nadav Goldstein: The best chrome extension out there! Super useful.
• (2021-08-12) Xujia Chen: Greatest extension ever. Have been using it over the years and in most cases it works beautifully. Occasionally it doesn't display for the receiver who probably uses an unusual mail reader, but that is quite rare.
• (2021-01-29) M L: 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) Siddhesh Wagh: 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
• (2017-09-14) 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.
