  • (2023-09-15) Vicky la Belette: étant en L1 de Physique, j'ai trouvé là un outil bien utile pour mettre mes cours au propre sur ordinateur du fait que je ne maîtrise pas le langage LaTeX. L'utilisation est très intuitive. Le manque de symbole mis à disposition aurait pu être un problème si on ne disposait pas de case vierge pour en créer. Je conseille !!!

  • (2023-04-17) Craig: Prior to installing the extension, I had considered suggesting a feature that would enable direct copying of LaTeX code from equations created using the extension. However, I was pleasantly surprised to discover that this feature already existed. I must say that this is an excellent extension. The only suggestion I have for improvement is to expand the catalog of symbols available.

  • (2023-01-14) Mike: I was looking for a Google Chrome extension to generate mathematical equations and came across the MATH Keys extension. I tried many other extensions, even the popular ones, however, I was not satisfied with those. As an Engineer in the fields of both Mining and Electronics, I am impressed at how simple yet effective the MATH Keys extension is. This is true engineering. I like how all I have to do is click on the extension and the formula elements just pop up, allowing me to generate formulas in less than a minute. This is very useful for a website that I am working on. Thank you for putting in the time and effort in delivering such a useful tool.
  • (2023-01-13) Zainab Charfare: This is Amazing. Just the thing I need. It works fine and good. But I am not able to put a multiplication sign between 2 digits. pls help me with that

  • (2022-11-15) Masako Yang: Woww this is so professional. It takes the rigmarole of clicking the equation button every time I want to write one in Google Docs out of the equation. Very helpful. One feedback is maybe add inverse trig. Not sure if they're needed often but would be helpful when you do.
  • (2022-11-15) Tess Wayland: Super helpful, streamlined my work a lot, elegant design!! Highly recommend.

Not only does it make it significantly easier to visualize my work online, it also eases the process of moving complicated equations with funky symbols from app to app (which I have seriously struggled with before). Couldn't recommend this enough!!

  • (2022-07-20) Noa Goldstein: I like writing all my notes for school on my computer, but it's usually so hard with math. This extension makes it so easy!
