Hi everyone, I'm Anton Vinogradov, the creator of Protein.
Protein sync design and source code of your projects in a team. It updates the source code with latest changes in design tools made on different platforms and vice versa. It's like GitHub for designers and developers. You can convert UI from source code to vector format and work with it in Sketch or AI. Also, you can convert UI from Sketch or AI to source code. When you'll change UI in design tools Protein sync changes with the source by pull request to the repository. Protein can deliver your design as sources or vector to online tools. You can work in Framer, Fuse, InVision and etc with your source code and design.
