Free online equation editor that utilises LaTeX to allow users to write mathematical equations, formulas, and symbols online
MATH Keys is a completely free online equation editor that allows users to write mathematical equations, formulas, and symbols online! Our mission is to boost productivity in academic life whether that is for teachers, graduates, or students.
Type out anything you want with your regular keyboard, and press the buttons on our MATH Keys to access mathematical symbols and operations.
With the latex notation tools, you can copy whatever formula, equation, or symbol you just created anywhere you want.
How to use:
- Use your computer keyboard to type your equation. You can use numbers,
letters, or any other symbol on your computer keyboard
- Use the extension MATH Keys to click on symbols, such as integrals,
sigma, fraction, etc..
- Navigate around using your mouse or use the arrows keys as follows:
- Right Arrow: move the cursor forward. This is useful to get out of operation.
- For example, if you are inside square root, forward arrow will move the
cursor out of it
- Left Arrow: move the cursor back
- Up Arrow: create exponent
- Down Arrow: create subscript
Use the buttons as follows:
- Copy Button: copy the formula as image to the clipboard — paste it wherever
you'd like
- New Button: delete the formula and start a new one

- Elise McGillivray
- I really like that I didn't have to learn Latex to use this. Super user friendly. Only qualm is that I have to open it every time and I cannot use it as a sidebar next to my paper. Also, you have to make sure it copies, cos sometimes it doesn't. I have found that making sure that the cursor bar is not blinking and spamming "copy" a few times usually ensures that it copies first try. Came in super clutch writing my senior thesis!!
- Anders Björling
- Very useful and easy thanks
- Aitor Zabala Muñoa
- It works great
- Blakely Bresee
- Extremely easy to use, and can work as a great extension for all sorts of popular apps! Has all the functions you can't find on a keyboard, and its auto-formatting is extremely intuitive and honestly satisfying after struggling to make professional looking formulas with just what Google Docs had to offer. Recommended!
- Jennifer Duffy
- Easy to use to insert math as images onto documents and slides to create my middle school & high school math resources. Always pleased with the professional look when I complete a project.
- Lee Carroll
- This extension has been helpful when making slideshows for my grade 9 and 10 math classes. It is easy to use.
- Jennifer Denson
- As a junior high math teacher, Math Keys is a life saver. My only gripe is that the extension closes every time I switch between tabs.
- Jaime Ray
- Absolutely awesome for a math teacher or student...
- Susama Mahnaz
- Great for quick LaTex codes
- Roberta Zasadzinski - Super Fun STEM
- So far so good
- Isaac Schober
- Works great, has a fantastic tool set and has been consistently handy in my college courses. I would recommend to people who are looking for a free hand math tool to use on homework assignments at any level.
- Melanie Rutter
- very helpful in adding math symbols to slides! I like that you can customize the buttons too.
- Ada Lloret
- Genial! :)
- Anthony Stark

- Gregorio Suino
- very useful app, woul be appreciated even more if the formulae were parametric and editable after publishing
- Steven Vasold
- Solid extension for using formulas in Google slides.
- Kerem S
- I liked this ext very much. When I'm using notion, I can arrenge and organise the formulas immediately. But I need symbols, math menu and more custom shortcut buttons. I recommend it for notion strongly if you are mathematian, scientist or engineer.
- Aten S Player
- The best extension to write equations even if the page doesn't allow it
- João Paulo
- what you see is what you get, though it lacks some common symbols on it's pre-selection so you need to add them yourself (such as Δ)
- Rebecca Alstatt
- I've been struggling since Equatio got rid of almost all of its free features, but this extension solved my problems! It makes inserting equations into any site so easy. Planning to have my students at it at the start of next school year, as well, so that they can use it.
- Elise Morris
- 5 stars from a virtual math teacher! Best equation writer I have used so far! Love the chrome extension so much!
- Vicki Schafer
- This is really helpful when creating math pages for my classes. I don't have anything else that fits the bill, though some features, such as closing every time I switch to Google, make it a little frustrating at times.

- Andy Kyle
- Easy and intuitive!
- Matt Wilson
- Handy to a point then kind of annoying. I write a lot of equations for electrical trade students and and its not always easy to get what I want out of the extension. try typing the word distance for example the app will force you to use "Dis tan ce" - I guess because Tan is a thing mathematically. It also annoys me that I cant get a nice X symbol without it looking like a variable - a few tweaks ant this plug in would be awesome
- Ruth Erquiaga
- Great!
- farid Jan

- It's great, and easy to use. There are a few improvements to be made with the Ui, but otherwise great.
- Margaret Steckel
- Very easy to use!!!
- Aya Schwartz
- I started using Math Keys a little while ago and to say it has changed my life is honestly an understatment. Having to Google "gamma symbol" and paste in the limited search results was frustrating to say the least and a waste of time. I don't think I would have known this was something I needed in my life but im so glad this was recommended to me!

- Free, not complicated, and creates great images of equations and other math symbols.
