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 run dev
To optimize the output for production run:
$ npm run bundle
Unfortunately this experiment does not work on iOS or desktop Safari (at least until Apple allows camera access from the web).
If you'd like to create a fork or a similar project, you'll need to setup some API keys on Google Cloud Platform.
