Yahoo has revamped its mobile news app, incorporating artificial intelligence capabilities from Artifact, a news app startup it acquired earlier this year. The new app provides users with highly personalized content based on their interests, using algorithms to process user behavior and serve relevant news stories. With AI-powered summaries and recommendation features, the app aims to revitalize Yahoo's news platform and improve personalization. The app curates articles from over 1,000 news websites, allows customization, and includes features to combat bias and misinformation.
