Free online contract multi-version comparison: Using baseline text as reference, compare multiple versions line-by-line and highlight additions/deletions, supports copying unified diff.

Tip: This tool is suitable for quick 'version comparison/clause change' checks; for complex contracts, it's recommended to first digitize (copy body or OCR) then compare.
