The artificial intelligence trying to level Twitter's toxic playing field

Tech start-up Areto Labs noticed online abuse was stopping women from going into politics – so it did something about it. "Imagine you have a job interview and every day, for a month, you have to walk down a dark alley, knowing the worst people in the world are in that alley and they will yell and scream at you," proposes Aucklander Jacqueline Comer, a creative technologist. "If you knew that, you wouldn't apply for the job. And, unfortunately, that's what women in politics have to put up with." Most people in the public eye cop some online criticism, but women get some of the most violent.
