Features
This will convert any text that looks like LaTeX inline math (beginning and ending with $) into an image of a well-formatted math expression. After installation, you can test it out on this Memrise course.

Installation
I have only tested this user script on Chrome using Tampermonkey, but it should work on other browsers as well.
Firefox
- Install the Greasemonkey add-on from Mozilla.
- Add this user script through Greasy Fork.
- Go to Memrise.com and try out the script.
Chrome
- Install the Tampermonkey extension on Chrome Store.
- Add this user script through Greasy Fork.
- Go to Memrise.com and try out the script.
Safari

- First up – download SIMBL and install it (installation consists of clicking ‘next’ a bunch of times).
- Exit Safari if you’re using it.
- Next, download GreaseKit. To install it, drag the GreaseKit.bundle file to ~/Library/Application Support/SIMBL/Plugins (note: if you don’t have a SIMBL/Plugins/ folder, just create it, then drop GreaseKit.bundle into it).
- Now re-open Safari. You should see a GreaseKit entry in the Safari menu bar.
- Add this user script through Greasy Fork.
- You’ll see a bunch of JavaScript fill up your browser window, and a Safari dialog box will appear asking you to confirm the installation. Click Install.
- Your GreaseKit menu will now include the installed script.
- Go to Memrise.com and try out the script.
Opera
This script won't currently work, since Opera does not support the GM_setValue functions.
