Better reading and research with annotation, highlighter, sticky notes, archiving, and...
Diigo is a multi-tool for personal knowledge management that helps people save, annotate, and organize online resources. It addresses the fragmented workflow of browsing, reading, researching, storing, and sharing information by keeping links, pages, notes, and annotations together in a cloud library that can be accessed from different devices.
Core features include bookmarks, tags, personal libraries, text highlights, sticky notes, an outliner for structuring research, and archived web pages that retain annotations even when the original source is unavailable. Collaboration features include groups for sharing collections and interacting through on-page annotations, with individual items set as private or public. The service runs on PC, tablet, and mobile platforms.
Diigo is aimed at individuals and teams who work with large amounts of online information, including researchers, students, teachers, consultants, and other professional groups. It uses a freemium model with a free option and paid subscriptions; archived web pages are identified as a premium feature.
