1. A method for enabling content discovery on a client device, comprising: providing, on the client device, a user interface (UI), the UI comprising: a concept bar presenting a user of the client device with a plurality of user-interactive concept tabs, the concept tabs associated with concepts currently relevant to a collaborative communication session involving the user and at least a second user using a second client device, each concept identified based on audio data corresponding to the collaborative communication session, wherein the concept tabs are arranged in an order indicating a relative importance of the concepts associated with the concept tabs to the user; and a content window separate from the concept bar and presenting the user of the client device with content relevant to the collaborative communication session selected responsive to the concept tabs presented by the concept bar, wherein the content presented by the content window is modified responsive to the user curating the content in the content window by interacting with the concept tabs, and wherein the presented content is selected from a set of content candidates associated with concept tabs presented by the concept bar such that a subset of highest ranked content candidates are selected for presentation.
