Diigo is a comprehensive research and knowledge management platform that transforms how users collect, annotate, organize, and share online information. Designed for students, researchers, educators, and professionals, it goes beyond basic bookmarking by allowing direct annotation of web pages and PDFs with highlights and sticky notes.
Diigo serves as a sophisticated research companion that enhances traditional bookmarking with advanced annotation capabilities. The platform enables users to save web pages while adding personal notes, highlights, and comments directly onto the content itself. This creates a personalized research library where original sources remain intact alongside user-generated insights.
Beyond individual research, Diigo facilitates knowledge sharing through collaborative groups where teams can pool resources and annotations. The system automatically organizes saved content through intelligent tagging while providing manual customization options for users who prefer specific organizational structures. This dual approach ensures both efficiency and flexibility in knowledge management workflows.
Diigo's web archiving feature preserves pages exactly as they appeared during research, protecting against link rot and content changes. This permanent storage, combined with cross-device synchronization, creates a reliable knowledge repository that grows more valuable over time as research collections expand and evolve.
Begin by installing the browser extension, which integrates Diigo's functionality directly into your web browsing experience. The extension provides quick access to saving, annotating, and organizing tools without disrupting your research flow. After installation, create a free account to start building your personal knowledge library.
Start saving web pages using the Diigo toolbar button, adding relevant tags during the saving process to establish initial organization. Experiment with highlighting text and adding sticky notes to become comfortable with the annotation features. Explore the outliner tool to structure related resources into logical research frameworks that support your specific projects or learning objectives.
Diigo provides various support options including email assistance and comprehensive documentation. The platform maintains an active user community where members share tips and best practices. For technical issues or account questions, users can access the help center through the website interface.
