We may be presented with cases where we only need to extract part of the contents of any website, leaving the rest of the page, that if we add it to some of the usual social bookmarking services, sooner or later we will forget the reasons that we had them added. And to extract contents from any website we have Wozaik.
The operation, how could it be otherwise, is based on a bookmarklet that we will add to the link bar of our usual browser, and each time we press it, allow us to indicate the area of content that we want to save, defining a series of labels as lists. We will already have these extracted contents in our panel along with other contents, which we can organize by columns, and which also, we will have different ways to share them with other users.
The use of this service is completely free, available in several languages, including Spanish, although the downside that we can put is that we do not have enough functions to customize our environment to our liking, in addition to not being able to eliminate created columns, only modify the area they occupy.
