Invisually is (Copied from their website):
"Designed to be used flexibly by the entire VFX production team, by Producers, Editorial, and Facilities.
The principle goal of Invisually is ease of use. Our application-like interface gives access to crucial data quickly and gives artists and management immediate results in managing the pipeline.
The approach is simple. You can start the show with Invisually at the breakdown stage, or import any spreadsheet or database file for instant integration. Add thumbnail images and Quicktime movies, and you are up and running.
Invisually tracks all shots and assets in the show. Individual records hold all notes, scanning info, past and present versions, and comments from all departments. Integrated email based tools automatically distribute client, vendor, and production notes."
