A Feed Reader is a tool that allows users to aggregate and read content from various websites in one place. It collects updates from blogs, news sites, and other online sources using a technology called RSS (Really Simple Syndication). This makes it easier for users to stay informed without visiting each site individually. Feed Readers can be web-based or available as applications on smartphones and tablets. They typically display headlines and summaries, allowing users to quickly scan for interesting articles. Popular examples of Feed Readers include Feedly and Inoreader, which help streamline the reading experience.
