It combines all the advantages of web based services like syncing across all your devices with everything you expect from a modern desktop program: Desktop notifications, fast search and filtering, tagging, sharing to "read-it-later" services like Pocket and Instapaper, handy keyboard shortcuts and a database that keeps all your old articles as long as you like.
FeedReader also allows you to save articles to read-it-later with the supported services for now: Instapaper Pocket Wallabag
