All InVision plans allow you to add unlimited collaborators to your prototypes.
To add a collaborator:
- Go into your prototype dashboard.
- Click the green share button at the top right.
- Add new collaborators to the project by entering their email address in the bottom box, or select other people you’ve collaborated with before and add them to your project. You can also send along a note with the invitation.
- Your collaborators will receive an email invitation to join the project.
