The subject of translating documents, words, lessons, etc...has come up several times in the last couple of weeks so I thought I would throw out some options!
In Google Docs:
If you have a document in your drive that you would like translated you are in luck! Google has made this super simple.
On a mobile device (iPad, iPhone, Android)
I used to have this amazing app called World Lens. It was used to translate signs, menus, and other basic information. It was fabulous! It has since been bought out. Guess who bought it?? If you guessed Google (which you probably did), you are correct! I have to say they have also made some big improvements to the app.
This is only a small representation of what is available to get you started!
