About this tool
Paste an original and a modified text. The tool shows added lines in green, removed lines in red, and unchanged lines in grey - line-by-line, like a tiny git diff.
FAQs
Is it line-based or word-based?
Line-based, similar to a unified diff. For word-level diffs use a dedicated tool.
How big a text can it handle?
Tens of thousands of lines work in modern browsers; very large inputs may pause briefly while computing.
Can it diff JSON?
It treats input as plain text. For semantic JSON diffing (ignoring key order, etc.), use a JSON-aware diff tool.
