Diigo is a personal knowledge-management tool for collecting, annotating, and organizing web material. While browsing on a computer, tablet, or phone, users can mark pages with highlights and sticky notes, then save links, pages, notes, and pictures in a cloud library. Saved pages can be archived and searched in full text. Groups can maintain shared repositories where members browse material and interact with page annotations. Diigo also supports saving items from social media, capturing links and notes by email, importing bookmarks from browsers, Delicious, or Pinboard, and exporting libraries and annotated PDFs. Its listed services include an API, blog auto-publishing, tagrolls, and linkrolls. Diigo offers a browser extension, apps for Android and iOS, and Quick Note on Mac. The free plan allows 1,000 bookmarks or notes and 200 highlights, but has limits on other items and groups. Paid plans are Standard at $5 a month and Professional at $6 a month. Diigo says browsing history is not recorded except for pages specifically bookmarked to its servers.
