Flask

Video review and collaboration workspace for teams and their agents

About Flask

Flask is a video review workspace where teams record, draw or type feedback directly on video, precise to the frame, instead of conveying creative feedback in text boxes. Agents and members can upload and organize assets, respond to feedback and share links, with all code, files and context saved alongside the video. It is built for creative teams and producers who review video work with clients and collaborators.
