I use frontify on a Daily basis as a content creator and, having a one stop shop for all assets it probably the best thing about this tool. Absolute time saver, It's super easy to search and navigate, friendly interface which makes it simple for anyone to use even if you're not a creator. I've had a few questions at some point and the customer support was super fast no responding me aswell as fast to help me providing a solution.
