Indeed very cool. Usabilla offers a same form of feedback: http://usabilla.com/products#usabilla_live (see also button on the right side of the page).

How it works:

1. You create a widget and add two lines of code to your site. 2. Visitors click the feedback button and can select highlight any part of the page to comment on. 3. Usabilla creates a screenshot (server-side) and shows feedback in a simple dashboard.

I find it annoying how you have to restart the tool for each individual element. Especially as you have to go through the How Does It Work screen every time. I think skipping the How Does It Work screen on subsequent pieces of feedback would be better.

Thanks. Would indeed be a small change that helps to improve the flow a lot.

We just deployed a change. When you give feedback for a second time (when you are still in the feedback flow), you won't see the intro dialog anymore.

How do you guys take a screenshot server-side for sites that require a login? Or does this only work for publicly accessible pages?

[pveugen]

Capturing sites that require a login works the same as other pages. We use the HTML output to capture a server-side screenshot.

but what if client had a crappy old browser but you rendered with modern browser, which will be rendered differently. Wouldn't be better if feedback contained computed HTML doms and you could render yourself with a given client?

[pveugen]

The really crappy old browsers won't see the feedback button. We do store and show HTML doms, which helps to debug if necessary, but most of our users collect feedback on such a large scale that it would be too time consuming to offer a manual solution like this.

You could do this client side with https://github.com/niklasvh/html2canvas
