To facilitate the review, evaluation and analysis of scientific literature, the lit-tag R Shiny application provides a convenient interface for users to generate a citation database with custom, user-defined tags and notes. Lit-tag is not subject-specific and is useful for any field of research. Starting with a table of citations exported from a Zotero library and a user-generated Excel file describing a set of tags and notes fields, lit-tag provides tools for assigning tags and notes to papers (lit-tag-builder module) and for exporting, graphing, and generating reports from the resulting database (lit-tag-viewer module). The application has been used in several scientific reviews related to marine carbon dioxide removal.
