Practical guide

How to use Compare Text

What this tool helps you do

Compare Text shows line additions and removals side by side. Within paired changed lines, it highlights changed words when the lines are short enough for an inline comparison.

When it is useful

  • Checking revisions to a draft
  • Comparing copied configuration snippets
  • Spotting a changed sentence or price

A practical example

Changing “Send the draft on Monday.” to “Send the final draft on Tuesday.” marks the replaced line and highlights final and Tuesday. The counts describe changed lines, not the number of changed words.

Limitations and common mistakes

This compares plain text, not document formatting or meaning. Moved lines can appear as a removal and an addition. Ignoring case or spacing can hide changes that matter in code. The download is a readable difference report, not a patch file for applying changes.

How to use Compare Text

  1. Paste the original on the left and the updated version on the right.
  2. Choose whether to ignore letter case or extra spaces.
  3. Compare the texts and inspect the red and green highlights.
  4. Download the difference report if you need to keep a text record.

Inputs and processing

Runs entirely in your browser with no text upload. Limit: 40,000 characters and 500 lines per side. Word highlights are shown for paired lines with at most 120 whitespace/word tokens per side; longer lines receive line-level highlighting. Ignore extra spaces trims lines and collapses whitespace; it does not remove blank lines.

Frequently asked questions

Is my text sent to a server?
