Have you heard about localization?
is the process of making something local in character or restricting it to a particular place.
So why this can be a project?
Projects (apps) are regularly written in the international language.
But sometimes they want to be in a different local language.
So yes, it's called localization.
There is some platform to help you localize the projects. They are also used by well-known open-source projects.
Something like Pootle or Transifex.
Regularly I use Transifex to contribute to open-source project localization.
I love the simplicity of doing localization in Transifex. They have a shortcut key to help the process faster.
Here is the shortcut I use.
Tab -> move to the next string
Shift+Tab -> move to the previous string
Ctrl+G -> copy source string
