Cozimo is a real time collaboration tool for getting feedback on digital content (images, videos or documents) from team mates or professionals.
Cozimo solves the problem of those people who want to get instant feedback on certain digital media content in real time, as email & any screen sharing software can’t solve this purpose.
This is how it works : You upload the digital media file in question and then invite other team members, an email invite goes to them and then they can give the feedback to you with the help of various annotation tools and for better feedbacks and communication they’ve also integrated chat with it.
However, this is not the only solution for this kind of work, ReviewBasics (our review of reviewbasics), ConceptShare have been providing this solution from long time.
But I’ve to agree to the fact that Cozimo loads pretty fast and offers a much cleaner interface.
