Skimzee is a free web app that combines web page summarization with social media search and web feed aggregation.
Skimzee automatically summarizes web pages - you can easily control how short or long a summary is simply just by moving a slider left or right. It also automatically discovers content that is relevant to the page you're summarizing.
You can search with it too - from the web, news sites, YouTube and Wikipedia. When you click the "view summary" icon in a search result you'll get a summary of the page for that link - all without having to navigate away from Skimzee.
If a search result has an associated video or photo, you can view them right in Skimzee eg. pictures from instagr.am in Tweets, embedded photos in facebook posts etc.
Skimzee also provides an easy-to use web feed aggregator - just add any feeds of your choice from the settings page and they'll appear in a drop-down list on the main page. From the settings page you can even search the Internet for any feeds you want and add them to your list. Just like for search results, each feed result can be summarized.
The Skimzee 'Feeds' tab lets you list trending and featured YouTube videos. It even integrates with facebook so that you can list your facebook feed or wall posts and summarize/display any links, photos and videos from each one.
The Skimzee extension adds a Chrome toolbar icon to let you automatically summarize the current web page. It also adds a very useful right-click context menu item for summarizing any link on a page.
