The concept isn't new, but the execution is well done: bring your library to your favorite tools, collect your files, and keep track of the versions you upload/update. The data is separated by your boards, so you can make f.e. client-sections. Furthermore, you can access a content library (beta for now) with assets.

As discussed with the helpful founder on an onboarding session, there are some nice features in development. Looking forward to those updates.

For me, it's simply a good deal because my data stored in Crafttor can be accessed in Figma through the Crafttor panel. That is really handy.
