Persai is a content aggregator that is specific to your interests. You specify a topic that you’re interested in with a few words, and Persai will find new content relevant to that interest and recommend it to you.

As you use Persai, it learns about you, and can better recommend content to you. Recommendations are based entirely on content, other users’ feedback has no bearing on what Persai recommends to you. As an example of this, they have taken two “interests” in Persai, stylized them, and put them on their own domains.

www.eyeonfacebook.com – created with the words “facebook, mark zuckerberg”
www.appleinsight.com – created with the words “apple, mac” .

These two sites are examples of content that you would see as a Persai user who is interested in Facebook and Apple. Of course, these sites are just for testing their classifiers; the persai.com consumer site will be much more interactive. Personally, they have been using it to follow news about the American subprime mortgage lending crisis and global warming.
