Diigo ( /ˈdiːɡoʊ/)[1] is a social bookmarking website which allows signed-up users to bookmark and tag web-pages. Additionally, it allows users to highlight any part of a webpage and attach sticky notes to specific highlights or to a whole page. These annotations can be kept private, shared with a group within Diigo or a special link forwarded to someone else. The name "Diigo" is an acronym from "Digest of Internet Information, Groups and Other stuff".[2]
Premium account holders can perform full-text searches of cached copies of bookmarks. A full-text search also searches page URLs, tags and annotations.[3] This means that premium account holders can choose to omit tags that already appear in the text of a page to be bookmarked (although text inside images cannot be searched).
The launch of Diigo met with mixed responses, from the unimpressed[4] to the enthusiastic.[5] Diigo beta was listed as one of the top ten research tools by CNET in 2006.[6]
Outside the website, Diigo's graphical user interface includes an optional bookmarklet, or a customizable toolbar, with various search capabilities. Highlight is enabled by a menu, that can either appear automatically when content is selected, or be embedded into the context menu.
In March 2009, Diigo acquired web-clipping service Furl from Looksmart for an undisclosed price.[7][8]
The site also has an extension available on the Chrome Web Store [9].
