Compare

Document comparison software compares two versions of the same document and produces a redlined output highlighting every insertion, deletion, and formatting change between them. This functionality is a staple of the legal drafting and negotiation process, allowing lawyers to quickly identify what has changed between drafts exchanged with a counterparty, or between an internal precedent and a client-specific version, without manually re-reading the entire document. Most tools support comparison across common formats, including word-processing files and PDFs, and can compare documents with different formatting or those converted from scanned copies. Output is typically a clean, shareable redline that itself becomes part of the negotiation record. Many comparison tools are now bundled into broader document management or productivity suites as a core add-on feature rather than sold as a fully standalone product, though dedicated comparison tools remain popular for their speed, accuracy on complex formatting, and ability to handle large or heavily revised documents reliably.
