Why not use Google Alerts?

Filtrbox picks up where Google Alerts falls short, delivering features professionals need to track and manage lots of information.
For example, Filtrbox maintains a history of articles discovered and sent to you so you never receive duplicates. Other key features of Filtrbox like contextual analysis, article and source feedback, and FiltrRank scoring mean that you don't just get the alerts, you get the content that is relevant without all the noise or a clogged inbox. With Filtrbox you cast a wider net and get the benefit of monitoring more places than just Google for new articles, without doing any more work. We are constantly adding new sources, and allow you to add your own via RSS.
