Introduction

The Text Diff tool compares two pieces of text and highlights differences such as additions, deletions, and changes. It is perfect for reviewing edits, checking configuration changes, or understanding how content evolved over time.

When to use this tool

Use this tool whenever you need to see what changed between two versions of text: code snippets, configuration files, documentation drafts, or content translations.

How to use

1

Paste the original text

Paste the older or baseline version of your text into the first input area.

2

Paste the modified text

Paste the updated or new version into the second input area for comparison.

3

Run the comparison

Click the compare button to generate a visual diff that marks inserted, removed, and changed segments.

4

Review and apply changes

Use the diff to understand exactly what changed, then decide which parts to keep, revert, or further edit.

Examples

Reviewing copy changes

Compare two versions of marketing copy or documentation to confirm that only the intended sentences were edited.

Checking config differences

Before deploying, compare the old and new versions of a configuration file to make sure no accidental edits slipped in.
