This paper describes accessible collaborative learning using mobile devices with mobile enhancements to Synote, the freely available, award winning, open source, web based application that makes web hosted recordings easier to access, search, manage, and exploit for all learners, teachers and other users. Notes taken live during lectures using Twitter on any mobile device can be automatically uploaded into Synote and synchronised with a recording of the lecture. Syntalk, a mobile speech recognition application enables synchronized live verbal contributions from the class to also be captured on Synote through captions. Synote Mobile has been developed as an accessible cross device and cross browser HTML5 version of Synote. Synote Discussion supports commenting on Synote's Synmark notes stored as discussions in its own database and published as Linked data so they are available for Synote or other systems to use.
