Text Diff
Compare two texts side by side. Additions are highlighted in green, deletions in red. The diff is computed locally — your input never leaves the browser.

How to compare two texts online
- Paste the original text on the left.
- Paste the changed version on the right.
- Toggle Ignore case or Collapse whitespace if you want a fuzzier match.
- Scroll through the side-by-side view — added, removed, and unchanged lines are colour-coded.
When this is useful
- Reviewing edits to articles, emails, or contracts.
- Comparing two versions of config or CSV files.
- Spotting unexpected changes in copied-pasted code.
Privacy
The diff runs entirely in your browser using a line-level longest-common-subsequence algorithm. No part of either text is uploaded.
