What is Text Comparison?

Text comparison (diffing) identifies the differences between two pieces of text at the character or line level. This is useful for comparing document versions, reviewing text changes, checking how two similar pieces of writing differ, verifying that edited text matches expectations, and inspecting configuration file changes. Unlike code diffs in Git, this tool works for any plain text — articles, legal documents, configuration, logs, or any string content.

How to Use the Text Compare Tool

1. Paste the original text into the left panel.

2. Paste the modified or compared text into the right panel.

3. The differences are highlighted: additions in green, deletions in red, and unchanged text in normal color.

4. Review the highlighted sections to identify every difference.

This text diff tool runs entirely in your browser — no data is sent to any server. Highlights added, removed, and changed content at the word or line level. Useful for document review, configuration auditing, and any text comparison task.

Frequently Asked Questions

Can I compare code with this tool? Yes. The text compare tool works for any plain text including code. For dedicated code diff with syntax highlighting and Git integration, use your IDE's built-in diff view or a tool like GitHub's diff viewer.

Does whitespace matter in the comparison? Yes — by default, all whitespace differences (extra spaces, different line endings) are shown as changes. Leading/trailing whitespace and different newline styles (CRLF vs LF) can produce noisy diffs. Trim your text before comparing if whitespace differences aren't relevant.

What is the difference between character-level and line-level diff? Line-level diff shows which lines were added or removed. Character-level diff shows the exact characters that changed within a line. Character-level is more precise for identifying small edits; line-level is cleaner for reviewing bulk changes.
