Instagram co-founders Kevin Systrom and Mike Krieger have introduced an AI-powered personalized news feed app as part of a new venture.  The Artifact app uses AI to learn a user's news interests and recommend articles and posts, similar to TikTok's algorithm. The app relies on an AI recommendation system that prioritizes time spent reading certain subjects to personalize a user's news feed. According to Systrom, the name Artifact is based on the ideas of "articles, facts, and artificial intelligence." For more than a year, a team worked on the news aggregation app, which is expected to have a social component and direct messaging in the future. The beta app is now available for both iOS and Android. It is now accepting signups via a waitlist. Artifact is the first product from Systrom and Krieger as part of their new venture focused on next-generation social apps. The two left Instagram in 2018, six years after Facebook acquired Instagram for $1B.
