Compare Contract Versions Online
Inspect legal edits, clause changes, and updated terms between contract drafts.
Compare the correct contract drafts
Use the last approved or reviewed file as the baseline and the new draft as the modified version. When both clean and redline copies are available, compare the clean draft against the last approved version to check the current wording.
The comparison highlights text changes in supported PDF and DOCX documents. It does not interpret legal effect, validate obligations, or replace review by a qualified professional.
Check material fields after the diff
After locating edits, verify names, dates, amounts, deadlines, renewal language, cross-references, and attachments against the source documents. Small wording changes can require a human decision about their meaning.
Scanned PDFs need a readable text layer for text comparison. If a file is image-only, run OCR first or inspect the relevant pages visually.
