Not a huge surprise given the lack of investment over the years and the rise of more full-featured competitors, but Google is shutting down its Translator Toolkit:
Google Translator Toolkit launched over a decade ago to help our users, translators, and the world create and share translations. When we first launched, there were few web-based options for translation editors, but now there are many great tools available, including Google Translate, which will continue to be available and is unaffected by this. As a result, we’ve seen declining usage for Translator Toolkit over the past few years. So now, after many years and billions of words translated, we’re saying goodbye to Translator Toolkit. A warm thank you to our users around the world.
