MailCat: an intelligent assistant for organizing e-mail

Mailcat is an intelligent assistant that helps users organize their e-mail into folders. It uses a text classifier to learn each user's mail-filing habits. MailCat uses what it learns to predict the three folders in which the user is most likely to place each incoming message. It then provides shortcut buttons to file each message into one of these three folders. When one of MailCat's predictions is correct, the effort required to file a message is reduced to a single button click.
