The global COVID-19 pandemic has put into high relief the need for better remote communication and collaboration tools, but also serves as an opportunity to focus on building community capacity and promoting greater community agency in the language documentation process. This paper describes a method for remotely supporting and monitoring a language documentation project conducted by speakers, community activists, and/or academic researchers, through the use of a free and open-source data collection platform called KoBoToolbox. Rather than relying on access to audiovisual data, which are typically large and can be difficult to share remotely, the system is based on the creation of digital linguistic metadata with mobile devices linked to a secure central server, giving project leaders the ability to immediately access metadata as it is submitted, quickly generate summary reports and visualizations, and export metadata for further processing and archiving. The system is suitable for anyone who would like to integrate mobile metadata into a new or ongoing project and is able to provide the necessary training either remotely or in person.
