An apparatus and computer program product for collaborating is disclosed. Responsive to a computer system receiving a selection from a user for a portion of a document, the computer system identifies a context for the selected portion of the document. The computer system identifies a set of collaboration channels corresponding to the context. The computer system determines whether the set of collaboration channels corresponding to the context is empty. The computer system then creates a new collaboration channel based on the context for the selected portion of the document responsive to the set of collaboration channels corresponding to the context being empty.
