Artificial intelligence made gains this month in the communication sector and in delivery.

Chase Bank announced that it has entered into a partnership with Persado, a New York-based company that uses artificial intelligence to write marketing copy. According to the company, in the three years since Chase has been under a pilot program with Persado, the ads created by Persado’s machine learning system outperformed the ads that were written by humans.

On the delivery front, Amazon revealed that the company’s self-driving robots, named Scout, will begin delivering packages to customers in Irvine, California soon. Each robot will be accompanied by a worker for the time being.
