Amazon's Alexa is gaining popularity in the U.S., but if you want to know the most popular chatbot in the world — by far — that would be Xiaoi, an intelligent conversational bot accounting for about 90% of the Chinese market, with some 500 million users, per Topbots' Adelyn Zhou.

Xiaoi, marketed by Shanghai-based Zhizhen, was introduced in 2004. In 2015, Microsoft won a major Chinese court battle against Zhizhen, which challenged patents for Siri, and now the U.S. company markets a rival text bot in China named Xiaoice, which has about 40 million users. But 40 of China's top 50 banks are Xiaoi clients, Zhou writes, and the 16-year-old company handles some 200 million interactions a day, the largest portion of which are from the financial sector.

Why it matters: Zhizhen appears to be exceedingly ahead of any western company in understanding the market for intelligent, natural language chat bots that interact smoothly with humans.

Xiaoil operates on on top of the wildly popular WeChat platform. Among transactions possible using voice recognition software through Xiaoi, clients make payments, transfer money, buy airline tickets, book rooms, order textbooks, and sign up for classes.

  • Zhou writes: "While US media continually lauds the achievements of IBM's Watson and Google's AlphaGo, we hardly ever hear of Xiaoi, a conversational AI giant whose bots — deployed to almost every business sector in China — have engaged 500 million users and processed more than 100 billion conversations."

Biden releases 2019 tax returns ahead of debate

Joe Biden's campaign released his 2019 tax returns on Tuesday, showing that he and his wife, Jill, paid nearly $300,000 in federal taxes last year.

Why it matters: The release, timed just hours before the first presidential debate, comes days after a bombshell New York Times report said that President Trump paid only $750 in federal taxes in 2016 and 2017. Biden's team is hoping to make the tax contrast a sticking point during their showdown.

New York City's coronavirus positivity rate has ticked up to 3.25%, its highest since June, Mayor Bill de Blasio said at a news conference on Tuesday.

Why it matters: The jump — from 1.93% on Monday — came on the first day that public elementary classrooms reopened in the city after months of closures, but guidelines state that all public schools will have to shut if the citywide seven-day positivity rate stays above 3%.
