Proof – Collaborate on Designs

Proof is a collaboration platform designed exclusively for designers. The streamlined interface gives designers a straightforward way to share their work instantly and discuss feedback with clients or colleagues directly.

Upload your first design into Proof by dragging and dropping it into your browser. You can zoom in or out, and add annotations by clicking directly on your design. Select the appropriate icon based on the type of feedback you’re soliciting—the question mark icon when asking questions, the exclamation point icon when flagging certain elements for review—and type in a note explaining the type of feedback you’re looking hoping to receive. When you’re ready to share your design, Proof gives you the option to copy/paste a shortened link or distribute your work directly through social networks like Facebook, Twitter, and Google+. Clients will be able to read your annotations and leave their own, as well.

Although most designers will use Proof for collecting feedback from clients or colleagues, the platform also serves as a useful tool for crowdsourcing opinions. Designers who post links to their projects on social media can encourage their followers to post comments and critiques. Proof organizes these annotations into discussions. For designers looking for a straightforward way to share and collect feedback on their work, Proof is an excellent solution.

Practical Uses:

  • Send mockups to clients for approval before moving forward with a project
  • Ask your colleagues what they think of a design you’ve created
  • Solicit feedback from fans on social media

Insider Tips:

  • Sign in to Proof through Facebook, Google, or with your email address
  • Select from one of eight icons when leaving feedback on a design
  • Press the quotation mark icon to view all comments along the right-hand side of the page
