Text Compare

Compare Text Online and Find Differences

Text Compare is a free online tool for comparing two pieces of text and quickly seeing what has changed. Paste your original text into the first box and the changed version into the second box to compare text directly in your browser.

The tool identifies added and removed words, shows whether the two texts are identical, and calculates a similarity percentage. It also displays word and character counts for both versions, making it easier to review edits and understand how much the text has changed.

How to Use the Text Compare Tool

1. Paste the original text into the Original text box.
2. Paste the second version into the Changed text box.
3. The comparison updates automatically as you type or paste text.
4. Review the additions and removals shown in the result.
5. Check the similarity percentage and comparison statistics.

If both versions match exactly, the tool will tell you that the texts are identical.

What Does Text Compare Check?

The comparison gives you several useful measurements:

• Similarity — shows how similar the two texts are as a percentage.
• Identical — tells you whether both versions match exactly.
• Words A and Words B — displays the word count for each version.
• Chars A and Chars B — shows the number of characters in each text.
• Added — counts words found in the changed version at compared positions.
• Removed — counts words from the original version that changed or were removed at compared positions.

These statistics provide a quick overview of the differences between the two versions.

Compare Two Texts Online

Manually comparing two versions of a paragraph or document can be difficult, especially when only a few words have changed. This online text comparison tool puts both versions side by side and shows the differences in the result.

You can use it to compare edited paragraphs, articles, descriptions, notes, drafts and other plain text. There is no need to repeatedly read both versions looking for small changes.

See Added and Removed Words

When the two texts are different, the comparison result marks words from the original version that have changed or been removed and shows words from the changed version that appear in their place.

This makes revisions easier to spot when checking an original draft against an edited version.

For example, if the original text contains:

The quick brown fox jumps

and the changed text contains:

The quick red fox jumps

the comparison will identify brown as changed from the original and red as the corresponding addition in the new version.

Text Similarity Percentage

In addition to showing differences, Text Compare calculates a similarity percentage based on the words being compared.

A higher percentage means more words match at the same positions in both versions, while a lower percentage indicates that more of the text differs.

The similarity score is intended as a quick comparison measurement. It is not a plagiarism score, AI-detection score or assessment of whether content is original.

When Is a Text Comparison Tool Useful?

Text comparison can be useful whenever you have two versions of text and want to identify changes quickly.

Common uses include comparing:

• Original and edited drafts
• Revised paragraphs
• Website copy
• Product descriptions
• Notes and written content
• Before-and-after revisions
• Two versions of plain text

Writers, editors, students, developers and other users can use the tool whenever they need a quick way to compare textual changes.

Text Compare works directly in your browser. You do not need to create an account or install additional software to compare text online.
