Disclosed is a collaboration system that synchronizes what is seen and heard by all participants to a conference such that participant input provided during the conference are seen and heard with respect to the same state of a presented asset. Additionally, the collaboration system may monitor the conference, may extract a first participant contribution prior to presentation of a first asset in the conference and a second participant contribution that is made during a particular interval of the conference when the first asset is presented. The collaboration system may link the second participant contribution to the first asset, may receive a request for the first asset after the conference has concluded, and may provide the first asset with the second participant contribution in response to the request.
