In their own words
DeltaCompare
DeltaCompare is DeltaXignia’s tool for finding and presenting changes in documents and data. It can identify structural edits, attribute updates, and moved content, with comparisons at the word or character level. It also detects changes within table cells and differences in diagrams or graphics embedded in documents. Results can appear as redlines or side-by-side views, or be produced as structured files for publishing and automation. Supported formats include XML, JSON, HTML, XHTML, DITA, DocBook, PDF, Word, Excel, and PowerPoint. Users can set rules to disregard whitespace, formatting changes, or selected elements, and choose how results are shown. Compare can run on its own, connect to content management systems and CI/CD pipelines, or be embedded in another product using Java or REST APIs. DeltaXignia describes it as suited to large data files and workloads involving thousands of documents. It is available on Linux, macOS, and Windows, as well as through API and self-hosted options.
SmarterDiff
SmarterDiff is a free browser-based tool for comparing text, Word documents, PDFs, spreadsheets, folders, and images. Text comparisons can show line, word, or character differences, with options to ignore case and whitespace. Excel and CSV comparisons check cell values and formulas, while image comparisons use pixel differences with overlay, side-by-side, and slider views. It can compare finalized.docx text, but not Word tracked-change markup; scanned PDFs without embedded text cannot be compared as text. SmarterDiff says comparisons run in the browser and files or results are not sent to its servers or external services. Comparisons can work offline after the first page load while browser libraries remain cached. File size depends on available computer memory and browser limits. It is a manual, one-off tool without workflow automation or integrations. The Free plan costs nothing, is ad-supported, requires no account, and has no artificial limits.
