Prisma bot and other A.I.-powered photo filters you've got to try

You've probably heard of Prisma, one of the hottest apps this year. Downloaded more than 50 million times since June and powered by artificial intelligence, it uses filters to transform any photo into a stunning work of art evocative of say, Pablo Picasso or a Renaissance master. It's trending in the App Store: ranked fourth in the free photo and video category behind Snapchat, Instagram, and YouTube. But you've probably heard less about the Prisma bot with similar features and the same name, launched less than a month ago on Telegram. It's notable that one of today's most popular mobile apps waited only about a month before launching a bot, and it begs the question: Are bots replacing apps?
