Work together

Team Prototyping

All members in your team can edit and make changes simultaneously to the same prototype at the same time. All project details and changes are registered for each version. You'll be able to see who did each modification or revision, create new web or mobile prototypes from them, and roll back to a previous version whenever you need to.

Agile prototyping
