Paste Both Versions
Free Text Diff Checker — Compare Any Two Texts
Whenever you need to know exactly what changed between two versions of something — a contract redline, an essay draft, a paragraph of code comments, or a translated document — scanning line by line by eye is slow and error-prone. This tool compares two blocks of text word by word and highlights precisely what was added, removed, or left unchanged.
How does the comparison work?
The tool breaks both texts into words and finds the longest matching sequence between them, then highlights everything outside that sequence — insertions in green, deletions in red strikethrough. This is the same underlying approach used by code diff tools like Git, applied to plain text.
What is this useful for?
Comparing two drafts of an essay or article, checking what a client changed in a contract, verifying a translation matches the original structure, or spotting accidental edits between two versions of any document.
