Hi. If I understand it's like parsing and putting a link extract for users next the content. So if it's that it can be help some.
But quick question, if I want the content and the video/photo under the same bookmark link. Will it not be as getpocket?.
If you don't mind. I will be more interested on the app that can track the update of the content or the comments or even the product price. But I don't know either if it's good idea.
Good luck.
