Imagine that you are working on a website project and your developer has sent you a mockup—a simple draft uploaded to a temporary server so you can review it immediately.

I used to work with clients who would print the mockup on paper, jot their comments across the pages, scanned it all, and sent it back to me. God help me if the client was a doctor—it took a while for me to decipher each scribble and symbol that they were trying to tell me.

Thankfully, now we have Designcrit.io—a tool where you can comment on any part of the page, on the fly, and share those notes directly with your developers.
