Compare two blocks of text line by line and highlight added and removed lines. Useful for reviewing document revisions, config changes, and copied-text verification.

-

Notes
- Comparison is line-based; a small edit marks the whole line as changed.
- Whitespace differences count as changes. Trim text first if you want to ignore them.
- Both texts stay in your browser and are never uploaded.
FAQ
- Does it show word-level differences?
- The tool compares lines. For word-level review, split long paragraphs into shorter lines first.
- Can I compare code?
- Yes. Line-based comparison works well for code, configuration, and structured text.
- Is my text uploaded?
- No. The comparison runs entirely in your browser.
