Text Diff Checker

Compare two text inputs line by line. Added lines are shown in green, removed lines in red, and unchanged lines remain neutral.

Practical guide

Using the Text Diff Checker

Compare two text inputs and review line changes.

Example

Input

Before:
color: blue

After:
color: teal

Expected result

A line-by-line comparison highlighting the removed and added color declarations.

Supported inputs

  • Two plain-text inputs for line-by-line comparison.

Limitations

  • The comparison is line-oriented; it does not understand programming-language syntax or identify semantic equivalence.

Frequently asked questions

Does the diff compare files?

Paste the contents of two files into the comparison inputs; the tool compares their text.

Why are nearby lines marked as changed?

The comparison works on lines, so edits that split or join lines can appear as removals and additions.
