Key features
Diigo
- Bookmarks, tags and a personal library
- Saved pages go into a cloud library and are tagged for later retrieval. Each item can be set as private or public.
- Highlights and sticky notes
- Highlight text and add sticky notes directly on web pages and PDFs while browsing; the annotations are still on the page when you come back to it.
- Outliner
- Arrange links, references and your own notes into a structured outline for a piece of research. Unlimited outliners are part of the Professional plan.
- Groups
- A group builds a shared library for a class, team or company that members can add to, search and discuss through annotations on the page.
- Archived web pages
- Paid plans store cached copies of bookmarked pages with their annotations intact, so they stay readable if the original source goes offline.
- Import, export and API
- The tools page lists bookmark and Kindle highlight import, library and PDF export, saving by email, automatic publishing to a blog and the Diigo API.
Linkwarden
- Full-page preservation
- Each saved page is captured as a screenshot, a PDF and a single HTML file, and can optionally be sent to the Wayback Machine for a snapshot.
- Reader view with highlights
- Saved articles open in a dedicated reader view where the font style can be adjusted and text can be highlighted and annotated.
- Collections, tags and AI tagging
- Links are organized into collections and sub-collections with multiple tags, and optional AI tagging labels new links based on their content.
- Sharing and collaboration
- Invite other people to gather links in a collection with permissions set per member, or share a collection and its preserved copies publicly.
- Search, RSS feeds and bulk actions
- Full-text search with advanced operators and filters, RSS feed subscriptions that add new articles to a collection, bulk editing, and import and export.
- Apps, browser extension and API
