App Inventor and AiLiveComplete are going Internationalized and will support multiple languages. It will allow you to switch language to your selected language. Once language is switched, all designer, blocks text will automatically translate to your selected language.
If you are interested to be a contributor to provide language translation, please see document HERE.

Hi Hossein, just a question, will you then share the completed translation to official MIT App Inventor? so we can all enjoy the result of this nice task you’re trying to accomplish, thanks!

Please see the instruction in the top Shared Google Drive.
In the files, there is a place that you can add your name and email address. When files uploaded to AI GitHub, it will show your name, email address.
I guess we could create a page of contributors (like the table that I have created in the Instruction document HERE.
