Compare two blocks of text

When two versions of something look almost identical, the difference is exactly what you cannot see by reading: one changed value in a config file, one edited clause in a contract, one line a colleague quietly added. Paste both versions here and the changes are highlighted line by line. Because the comparison runs locally, this is safe for contracts, configuration, and unreleased code.

How to compare two blocks of text

  1. 1

    Paste the original

    Put the earlier or reference version into the first panel.

  2. 2

    Paste the new version

    Add the changed text to the second panel and the comparison runs immediately.

  3. 3

    Review the highlights

    Added, removed, and unchanged lines are marked so you can scan straight to what moved.

Good to know

  • Comparison is line by line, which suits configuration files, code, and structured text best.
  • Identical text produces no highlights at all — a clear answer that nothing changed.
  • Whitespace and indentation differences count as changes, which is usually what you want when diffing code.
  • Both inputs stay in the page, so confidential documents never get uploaded to a diff service.

What people use it for

  • Finding the one changed setting between a working and a broken config file
  • Spotting edits between two drafts of a contract or article
  • Comparing a snippet you were sent against the code you already have

Frequently asked questions

How does the comparison work?+

It runs a line-by-line longest-common-subsequence diff and highlights added lines in green and removed lines in red.

Is my data sent to a server?+

No. Comparing text happens entirely in your browser using built-in web APIs. Nothing is uploaded, stored, or logged.
