Crowdsource is a crowdsourcing platform developed by Google intended to improve a host of Google services through the user-facing training of different algorithms. Crowdsource was released for the Android operating system on the Google Play store on August 29, 2016, and is also available on the web. Crowdsource includes a variety of short tasks users can complete to improve many of Google's different services. Such tasks include image label verification, sentiment evaluation, and translation validation. By completing these tasks, users provide Google with data to improve services such as Google Maps, Google Translate, and Android. As users complete tasks, they earn achievements including stats, badges, and certificates, which track their progress.
