How to compare two texts online

Paste the original text in the left panel and the modified version in the right panel. A line-by-line diff is generated instantly: green lines are additions, red lines are deletions, and identical lines are hidden to keep the view focused on what changed. Each side supports up to 500,000 characters.

Common uses: comparing two versions of a contract or policy to identify what changed, reviewing edits in a text file without version control, spotting differences between two scraped web pages, or verifying that a copied passage matches the original source exactly.
