LaTeX Diff: compare two versions online
Upload the old and new .tex files (or project .zip archives) to get a PDF with additions and deletions marked (powered by latexdiff). Your files are never stored.
Old version: drag a .tex or project .zip here or click. Max 5 MB (.tex) / 10 MB (.zip).
New version: drag a .tex or project .zip here or click. Max 5 MB (.tex) / 10 MB (.zip).
For the revision itself: Revision Review ($2) checks the revised manuscript against an earlier Paper Review, and Response to Reviewers ($6) reads your response letter against each comment.
Changes inside tables are shown in final form only (not marked). Files are never written to disk.
