Text Compare — FAQ
Paste the first text on one side and the second text on the other, and the tool highlights the differences line by line. Everything runs in your browser, so your texts never leave your device.
Added lines appear only in the second text, removed lines appear only in the first text, and common lines appear in both. That split shows exactly what changed between versions.
The comparison works line by line, so a changed sentence shows as a removed line plus an added line. It does not highlight single changed words inside a line.
It is handy for checking revised essays, contracts, code, translations and articles, where spotting what changed between two drafts matters more than reading both fully.
No. Both pasted texts stay exactly as you entered them, and the comparison is only a view of the differences.
Yes. Paste both texts in full and the tool compares them in one pass, which is far quicker than reading two long documents side by side.
Yes. A line that differs only by spaces or a blank line counts as a different line, so cleaning extra spaces first gives a cleaner comparison.
No. The tool is free to use with no account or signup required.
No. Everything runs in your browser and no text is uploaded anywhere.
No installation is needed. The tool runs entirely in your web browser and is completely free.
