do•doc (or dodoc) is a free and open-source documentation tool, initially designed for use in classrooms with children. It enables one to capture traces from an on-going experience for later reflections, reconstructions and creation of narratives. A physical device can be associated with the software to simplify usage, especially with young people. Two versions are available: the local app that can be installed for offline use, and the online webapp that can be accessed from any device connected to the Internet.
