In-App Feedback - Screenshot w/ Annotation Feature

I can’t think of any slick web-based image annotation tools.  I agree it would be slick - but I’m not sure how feasible it really would be. 

What tools do you use that we should emulate? 

I use Camtasia Snagit.

That’s a great product.  But its not a web app.  I’ve not seen effective annotation and image manipulation capabilities added to a browser app… Have you? 

Google search yields nothing that is a perfect match. All sorts of URL based screenshot API’s.

Build your own. 😉
