Save, tag, annotate, organize, and share online resources.

Diigo is a free social bookmarking, research, and knowledge sharing tool created to mimic the ease of taking notes while providing a network for sharing and discovering information.

Key features

  • Read more effectively with annotation tools as you browse around the web. Add digital highlighters and sticky notes whether on PC, tablets, or mobile and have them always be where you left them when you return.
  • Build your personal library in the cloud, with links, pages, notes, pictures, etc., never to be lost, and ready to be accessed anywhere. Of course, those digital highlights, sticky notes, and screenshots you added while navigating the web will automatically be added to your library.
  • Want to prevent broken links? The web is dynamic - valuable content you found earlier is often no longer there when needed. Diigo archives the webpages for the links you save. Better yet, the archived pages are fully searchable.
  • Provide feedback with annotation or screenshots. Want to point out something to your Twitter followers ? Highlight it and tweet. Want to comment on a student’s writing? Use sticky notes for inline commenting. Want to provide feedback on a web design? Capture the page and mark it up.
  • Share information, as much or as little as you want. One advantage of storing information in the cloud is that you can share easily when you want to. Information can be set as private or public on Diigo.
  • Enable better collaboration on information for any group, large or small. Are you experiencing too little or too much sharing with email? Build a group knowledge repository for your team; each group member can add and subscribe to it and browse and search it. Group members can interact with on-the-page annotations.
