FeedAgent

FeedAgent is an intelligent RSS reader that learns what interests you and uses that knowledge to determine whether new information should be brought to your attention.

Designed for those who want to stay up-to-date on what they care about but find it increasingly harder to find that information by themselves, FeedAgent is an easy way to increase productivity by automating this task.
Supports all major feed standards and includes access to an on-line feed directory with hundreds of feeds.
FeedAgent is free and contains no ads.
