Symbaloo is a web tool that allows users to create, share, and discover webmixes. A webmix is a collection of links organized by topic that can be accessed from any device. Users can create a free account to save webmixes, organize bookmarks, and share curated links with others. The tool provides an easy way to publish webmixes publicly or privately and get embed codes to share mixes on other sites. Users can also discover pre-made webmixes on various topics added by other Symbaloo members.
