LeCTo recorder is a simple free tool for recording (one or many) cameras and the desktop.
Lecturer can prepare his presentation in PowerPoint.
A plug-in for PowerPoint can be used to contextually add links, web pages, quizzes and FAQs to the presentation.

  • recording both lecturer and everything he shows on The desktop, possibly other cameras (showing experiments, audience, …)
  • publishing parts of LeCTo content anywhere on the web, in different locations,
  • modifying and rearranging additional content for different uses.
