DiffPaper helps you compare revised drafts, contracts, proposals, and review copies directly in the browser. The product focuses on local-first comparison so teams can review changes without shipping documents to a remote server.
Upload an original file and an updated version to inspect additions, removals, and modified blocks side by side. DiffPaper keeps the review flow simple: upload, compare, navigate changes, and clear the files when you are done.
The current workflow is a good fit for legal redlines, procurement documents, statement-of-work revisions, policy updates, and any review process where version drift matters.
DiffPaper highlights changed blocks, supports synced scrolling, and helps reviewers jump between differences quickly. This keeps attention on the actual edits rather than on manual line hunting.
