CEO Mark Zuckerberg announced the new tools in a video which was exhibited during the event. The new AI tools will use behavior on Facebook and Instagram to target the messages to those customers most likely to be receptive to them, provided the customers use the same opted-in phone number across accounts. WhatsApp's head of strategic markets Guilherme Horn told Reuters that these AI tools would give business the possibility to optimize ad delivery to users most likely to engage. It also announced it's adding Brazil's instantaneous digital payment method PIX, once seen as a potential competitor, to its WhatsApp payment tool in the country. WhatsApp similarly started offering payment services from rival providers in India last year.
