Litera Compare vs SmarterDiff

Litera Compare helps users compare document revisions across authors and file formats. Comparisons can cover complete documents or selected snippets, including text, code, images, tables, charts, and comments. Results group changed elements by type and quantity so users can filter, modify, or flag them. Users can save redlines, make a merged version, or create a new document retaining the original formatting, then print or email it. Google Workspace users can start comparisons from Google Docs, Google Drive, or Litera’s web application. Litera also offers Compare for Microsoft 365 with the same comparison engine. The cloud-based Compare Office 365 app compares, cleans, and converts documents, spreadsheets, and presentations. Compare Desktop runs on Windows; Mac and Linux require a Windows virtual machine or dual boot. Desktop integrations include NetDocuments, iManage, OpenText eDOCS, and Worldox. The Desktop license is a one-year subscription, and online purchases are limited to 10 seats.

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.
