Your files stay on your device Literature review matrix builder Build a synthesis grid with sources as rows and your own columns, with theme coverage counts and completeness flags, exportable to CSV or print. Paste sources and columns, or load the sample preset, and the matrix builds here. The two diagnostics are the point: theme coverage counts how many sources carry each tag in a column whose name contains Theme, and a tag with a single source is flagged tentative rather than treated as a finding; column completeness counts non-empty notes per column and flags the ones under half filled. Parsing keeps going past bad lines, so one malformed entry rides along as a title-only row with a warning instead of eating the paste. Everything runs in this tab and nothing persists: leave the page and the matrix is gone, so copy the CSV or print before you close it. No reference manager features live here: no DOI lookup, no style formatting, no duplicate-key merging beyond the flag.
