Our attention is increasingly dominated by social networks and share-based algorithms which promote sensational and inflammatory content with the sole purpose of driving click rates and maximizing “time spent.” Ration gets users out of the social media echo chamber and encourages intentional and efficient content consumption. Ration helps users hone their media diets and consume better, not more. Ration is a mobile app that will be an advertisement free, pay-what-you-want service. Users receive a daily Ration of articles, videos, podcasts, and music personalized to their interests. Human curators act as the first filter, selecting a finite, high quality pool of content each day. Interest-graph-driven-AI selects content from the curated pool that fits each user’s personal taste and makes additional recommendations that allows the user to expand their horizons.
