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.
Diffchecker
Diffchecker compares text, code, and data in a browser or offline with its desktop app, highlighting additions, removals, and edits. Text comparisons can use side-by-side or unified views, adjustable precision, custom ignore rules, syntax highlighting, real-time editing, and change merging. Listed comparison options also include documents, images, spreadsheets, and folders, with features such as OCR, redlines, formula detection, and batch comparison. Basic is free, but some tools have monthly use limits: unified view and real-time editing each allow five tries, while character-level differences and merge changes each allow ten. Pro + Desktop costs $15 a month per user and includes offline comparisons with desktop apps for Windows, Mac, and Linux. Legal costs $20 a month per user and adds iManage integration and comparison-setting profiles. Enterprise costs $40 a month per user with annual billing, and includes SAML SSO, SCIM provisioning, and dedicated support. Browser comparisons stay in the browser unless saved and shared; Desktop comparisons run locally. The site states browser traffic is TLS-encrypted and its security program is ISO/IEC 27001 certified.
