Hi Hunters,
I built and launched a free latexdiff online tool for researchers working on LaTeX papers and journal revisions.
You can:
Compare two .tex files or full LaTeX projects
Generate tracked changes with latexdiff
Create the "changes marked" version journals often request
Review revisions before resubmission
No Perl installation, terminal, or setup required. Just upload your files and get the diff instantly.
Files stay private. We process the diff and discard the input immediately.
Would love feedback from researchers, reviewers, and anyone dealing with journal resubmissions.
