Text Diff Checker
Compare two blocks of text and find their differences directly in your browser.
Compare Text Online
Compare two blocks of text side by side and quickly identify lines that were added, removed or changed.
Find changes between two texts
Paste the original text on the left and the changed text on the right. The diff checker compares their lines and highlights the differences.
Ignore case and whitespace
Optional comparison settings let you ignore differences in uppercase and lowercase letters or surrounding whitespace.
Private browser-based comparison
Your text is compared locally in your browser and does not need to be uploaded to the HandyKitz server.
Practical example
Use the original text on one side and its revision on the other. The comparison checks lines, so even a small edit can mark a line as changed.
Compare status: draft with status: published to spot the changed line. Enable ignore-case when uppercase and lowercase differences are irrelevant.
Frequently asked questions
Does the checker compare individual characters?
The comparison is line-based. A small edit can therefore mark a whole line as removed and added rather than highlighting just one letter.
Does ignoring whitespace ignore spaces inside a line?
No, it trims whitespace at the beginning and end for comparison. Differences between words inside the line still count.
Why is a moved paragraph shown as a deletion and addition?
The checker matches line sequences; it has no separate moved-block category. A relocated block may appear removed in one place and added elsewhere.
