Redline Compare is a web service for comparing original and edited documents for legal teams. Upload both versions and receive a redlined document that highlights their changes; the site says results are returned in seconds. It supports PDF and DOCX comparison and lists all file formats in both plans. Documents are processed with enterprise-grade encryption, according to the site. The product focuses only on redlining. It does not include document storage, user-management systems, or collaboration tools. The Free plan costs nothing and provides 50 document comparisons. Pro costs $4.99/month and adds unlimited redlines and priority processing. Both plans list professional accuracy and all file formats. Redline Compare describes its pricing as having no hidden charges, with payment directed only to redlining. It runs in a web browser, with PDF comparison, office-file comparison, and redline output provided through the web deployment.

UltraCompare compares and merges files, folders, and documents, including Word, Excel, and PDF. It can show two or three files side by side and lets users merge differences visually. Folder tools compare, merge, and synchronize directory structures, with rule-based automation available. For spreadsheets and other tabular data, it can compare and merge cells, rows, or columns, including across multiple Excel sheets. UltraCompare works as a diff and merge tool with Git, Subversion, and CVS. It can compare remote files over FTP or SFTP and by URL, and folders over FTP and network shares. ZIP, RAR, and JAR contents can be compared without extraction. Additional tools include highlighting for characters, words, or lines; options to ignore whitespace or case; editable comparisons; saved sessions; and HTML or text reports. The maker lists Windows, macOS, and Linux, while a fully functional Windows trial includes all features for 30 days. There is no free plan.
