Reading two versions of a text in turn makes it easy to miss exactly what moved or changed.
Text to Text Comparison places the two versions next to each other and highlights every addition and removal.
How to use Text to Text Comparison
- Paste the first text on the left and the second text on the right.
- Keep the Side by side layout, switching to Inline or Unified if you prefer, and toggle Ignore case or Ignore whitespace.
- Read the aligned differences, then copy or download them.
Use cases
- Comparing two drafts of a document side by side.
- Reviewing a revised paragraph against the original wording.
- Checking a pasted copy against a reference version.
Good to know
Text to Text Comparison aligns the two texts line by line with a longest-common-subsequence diff and defaults to a side-by-side layout so the original and changed versions sit in parallel columns. The ignore-case and ignore-whitespace options affect matching only, and everything runs in the browser with nothing uploaded.
Frequently asked questions
How does the side-by-side view work?
The original and changed texts are shown in two columns with differences highlighted, so you can read across to see what changed on each line.
Can I switch the layout?
Yes. A layout control offers side by side, inline, and unified views of the same line comparison.
Is my text uploaded to compare it?
No. The comparison runs entirely in your browser, so both versions stay on your device.
