Compare Text — Text Diff Tool

Paste two versions of a text and see additions and deletions highlighted line by line.

Original / Version A
Edited / Version B
Diff Result − removed + added unchanged

Paste text in both boxes above to compare.

How to Use the Compare Text Tool

  1. Paste your original (or older) text into the left box labelled "Version A".
  2. Paste your edited (or newer) text into the right box labelled "Version B".
  3. The diff output updates automatically — lines highlighted in red were in A but not B (removed), lines in green appear in B but not A (added), and neutral lines are identical in both versions.

Common Uses for Text Comparison

  • Proofreading: Compare a client's brief with your draft to make sure you haven't missed any requirements.
  • Document version control: Track what changed between two exports of the same document.
  • Plagiarism checking: Spot whether two submissions share identical passages.
  • Legal and compliance: Compare contract versions to identify changed clauses.
  • Content updates: Before publishing a revised article, confirm exactly what changed from the published version.

Limitations

This tool performs a line-by-line comparison — it does not do word-level or character-level inline highlighting within a changed line. For a full word-level diff, a desktop tool like VS Code's built-in diff editor or git diff is recommended. For a quick, browser-based view of which lines changed, this tool is fast and accurate.

Proofreading two versions of a document, checking whether a client's edited draft differs from your original, verifying that a translation preserved all paragraphs, reviewing changes before publishing an article update, or comparing two code snippets.
