Alphabet's AI-powered Chrome extension hides toxic comments

Alphabet offshoot Jigsaw is launching a Chrome extension designed to help moderate toxic comments on social media. The new open-source tool, dubbed "Tune," builds on the machine learning smarts introduced in Jigsaw's "Perpesctive" tech to help sites like Facebook and Twitter set the "volume" of abusive comments. Using "filter mix" controls, users can either turn toxic comments off altogether (what's known as "zen mode") or show selective types of posts containing attacks, insults, or profanity. Tune also works with Reddit, YouTube and Disqus.
