Koral

KORAL Content Collaboration.

Koral is a web based Ajax application which helps to organize all the information in documents, folders and share them with the other people.

I’ve just had a demo of Koral. The User Interface is very slick and easy to use. It makes heavy use of Ajax and is actually SUPER FAST. Some of the good features in Koral includes

• Version Control, Online Previews.
• Once a file is uploaded it is automatically indexed and recommends a series of tags which makes searching much easier.
• Allows users to subscribe to individual files.

BTW it is free for basic usage. Koral screenshots in Flickr can be seen here.
