1. A computer-implemented method for integrating personal information search and interaction on web and desktop applications comprising: enabling, by an information handling/computer system, a user-interface (UI) component of an application to enter a query of a personal information repository, based on a request for information by said UI component; in response to said request, receiving natural language information that is entered into said information handling/computer system; parsing, by said information handling/computer system, said natural language information based on a natural language grammar, to determine at least one natural language element; generating, by said information handling/computer system, element types associated with each of said at least one natural language element; selecting, by said information handling/computer system, a command from a command list based on matching arguments of said command to said element types and type information that indicates those element types that substitute for said arguments; executing, by said information handling/computer system, said command based on said matching arguments to determine a result from said personal information repository to said query; outputting, by said information handling/computer system, said result through said UI component by replacing said result for said request for information by said UI component to automatically add any of email addresses, attachments, and maps to said UI component.
