Applications that collect data from RSS-compliant sites are called RSS readers or "aggregators." RSSOwl is such an application. RSSOwl lets you gather, organize, update, and store information from any compliant source in a convenient, easy to use interface, save selected information in various formats for offline viewing and sharing, and much more. It's easy to configure, available in many many languages and the best of all: It's platform-independent.
RSS ("Really Simple Syndication" or "Rich Site Summary") is a document specification that gives users the power to collect and organize Web-based news and information in a more efficient manner.
The owl is a traditional symbol of wisdom, and a quiet, efficient hunter. You'll find RSSOwl's "big eyes" a big help when scanning the Web's vast array of RSS sources.
