Recogito is a software platform that facilitates annotation of text and images. Through both automatic annotation and manual annotation by users, the software links uploaded files to geographic data and facilitates the sharing and downloading of this data in various formats. The software is freely available for download through GitHub, and a version is also hosted online. In the online version, users have a private workspace as well as the ability to share documents among a group or publicly. Recogito was developed from 2013 to 2018 as part of the Pelagios network, a much wider project dedicated to creating gazetteers and tools for annotation, visualization, pedagogy, collaboration, and registering linked data.
