The ProPublica News Apps team on Tuesday released Transcribable, an open source version of its Free the Files project, a web application that enabled the team to crowdsource a massive cache of campaign advertising spending documents.

The open source version allows anyone with a DocumentCloud account to create their own application and start crowdsourcing their own documents.

ProPublica developer Al Shaw wrote about the the project in further detail at The ProPublica Nerd Blog. You can find the project itself on GitHub.
