LaTeX has been around for about 35 years, and it has made it a lot easier for scientists to add complex mathematical expressions, as well as non-Latin scripts such as Chinese, Sanskrit, and Arabic to their academic or research papers.

Although highly beneficial, adding LaTeX content to your documents can also be quite time-consuming, unless you have a dedicated tool designed to make it a lot faster to generate LaTeX markup output.

Mathpix snipping tool is one such utility, a free and user-friendly app designed to work just like the built-in macOS screenshot engine to help capture mathematical equations and instantly convert them into LaTeX markup, ready to be added into your paper.

Once launched on your Mac, Mathpix snipping tool will add its own status bar menu item, and it will stay out of your way until the moment you need it to snapshot a math equation.

To convert an equation into LaTeX format, you can either click the "Get Latex" option in Mathpix snipping tool's status bar menu or use the ⌃+⌘+M (CTRL+COMMAND+M) keyboard shortcut.

If you don't like the pre-defined snapshot hotkey, you can quickly change it from the Preferences dialog, as well as set the app to launch automatically on login by toggling the "Start at Login" button.

Mathpix snipping tool also enables you to change the LaTeX output format by choosing one of the five options available in the "Format" sub-menu.

Once you snapshot an equation, Mathpix snipping tool uses an OCR-based image recognition engine to identify the mathematical expressions in your screenshot and then it copies the result into your Mac's clipboard.

It is also relevant to mention that Mathpix snipping tool is capable of helping you capture math expressions in both handwritten and printed form, thus allowing you to convert equations from all possible sources.

Everything considered, the Mathpix snipping tool app is a huge time saver for any Mac user who has to work with complex mathematical expressions and LaTeX documents on a daily basis because it makes the task of creating LaTeX formatted expressions a lot faster and easier.
