How to Use:

Start by pasting or typing content into both input boxes. If you already have files to compare, use the Choose File buttons under each box to import them. The comparison updates live as you type or load new content.

In the Options section, you can tweak how the comparison works. Choose to ignore letter casing, strip extra whitespace, or display only the lines that differ. Your results will appear below in a readable, line-by-line format. You’ll also see a live character count and buttons to copy or export the results.

What the Compare Text Tool Does:

The Compare Text Tool performs a side-by-side line comparison of two inputs. It identifies which lines match and which don’t. You can choose to hide matching lines, normalize whitespace, or make the comparison case-insensitive. It shows each differing line from both inputs with clear labeling, helping you spot changes quickly. The tool runs entirely in your browser and updates instantly.

Compare Text Example:

Input A:

The quick brown fox
jumps over the lazy dog

Input B:

The quick red fox
jumps over the lazy dog

With Ignore case: off, Show only differences: on

Output:

Line 1:
A: The quick brown fox
B: The quick red fox

Common Use Cases:

The Compare Text Tool is great for reviewing code, validating copy edits, finding differences in logs or config files, and debugging changed content. Writers, developers, QA testers, and editors can all use it to quickly identify what’s changed and where, without needing any installs or logins. It’s simple, fast, and keeps your content private.

Useful Tools & Suggestions:

If you’re spotting changes or duplicates, Calculate Levenshtein Distance gives you a numeric value that shows how similar two pieces of text really are. And for summarizing the differences more clearly, Highlight Patterns in Text can visually call out overlaps, changes, or repeated structures.
