Thing Translator is a web app that lets you point your phone (or laptop) at stuff to hear to say it in a different language. It was developed as part of Google's AI Experiments project. You can try the app here.
Behind the scenes Thing Translator is using Google's Cloud Vision and Translate APIs.
To start a development server on 9966 that will watch for code changes simply run:
$ npm start
You will need to set your API key in src/config.js.
To optimize the output for production, run:
$ npm run build
For production builds, replace the contents of the api_key file with your
production key.
If you'd like to create a fork or a similar project, you'll need to setup some API keys on Google Cloud Platform.
