    Here's the website: http://markup.io/ We created MarkUp at Medium to help make the QA process better for sites we're working on. Grab the MarkUp bookmarklet, go to some page in your browser, then click it to draw on the page. Publish to make a link you can share. We've tried similar tools like BounceApp, Notable, and Skitch.
