Love them or hate them, inspirational quotes or captions for selfies are rife on social media. Whether from politicians, gurus or authors, they're everywhere -- so a Brazilian publishing house had the clever idea of using them for marketing purposes. LeYa Books created a bot that will suggest a suitable quote from one of its new authors for any photo or general sentiment you want to convey. Users simply describe the photo or what they want to say, and the tool, created by WMcCann in Rio, will choose the perfect literary caption. After choosing the quote, the bot sends a link to the consumer giving them opportunity to buy the book in question. "We connect to the audience through their language, we bring the fundamental beauty of authors and words to the richness of images, and we nurture reading," commented Leila Name, general director, LeYa Brazil.
