chandler is a Personal Information Manager (PIM) intended for use in everyday information and communication tasks, such as composing and reading email, managing an appointment calendar and keeping a contact list. Because of the ease with which Chandler users can share information with others, Chandler might be called the first Interpersonal Information Manager.

With Chandler, users will be able to organize diverse kinds of information for their own convenience -- not the computer's convenience. Chandler will have a rich ability not only to associate and interconnect items, but also to gather and collect related items in a single place creating a context sensitive "view" of many types of data, mixing-and-matching email, mailing lists, instant messages, appointments, contacts, tasks, free-form notes, blogs, web pages, documents, spreadsheets, slide shows, bookmarks, photos, MP3's, and so on (and on). Data in Chandler is stored on repositories on the user's local machine, on others' machines, and on shared resources such as servers.
