According to the team, the new Stand In will let you:

1. Share your prototypes with teammates and clients. Let them experience your designs on their devices instead of scrolling through PDFs on their computers.
2. Design and use your prototype in real time. As you make changes in Photoshop, Stand In sends the changes to the fully functional prototype.
3. Move past boring static screens. Add buttons with press states, content that scrolls, modals, and more!
4. Bring your prototype to life with screen transitions and animation. Stop telling people how the app is supposed to work. Start showing them.

The tool costs $25/mo. & requires a Mac running Photoshop CC.

“Much more than image extraction,” writes Photoshop’s Tim Riot, “Stand In takes positioning, styling, state, even motion data, from PSDs and creates prototypes that feel like real apps which you can view on your iPhone. This capability, to fluidly create in Photoshop and seamlessly output designs to any context, is at the heart of the Generator technology.”
