Text Comparison / Line Difference Check | After 6 Toolbox

A web tool for confirming only the changed lines after rewriting guidance documents or instruction manuals.

How to Use

1. Paste the text before changes on the left and the text after changes on the right
2. Added lines are displayed in green, deleted lines are displayed in red
3. You can copy the comparison results with "Copy Diff"

For example, if you change "Reception is from 9 o'clock" to "Reception is from 10 o'clock," you can view the original line and the new line side by side. The screenshot shows a test using a fictional guidance document.

Comparison is done on a line-by-line basis. It does not perform layout comparison for Word or PDF files, nor does it judge the correctness of text.

After 6 introduces the text comparison feature in Toolbox as a standalone page that can be used immediately. It is produced and operated by After 6 Labo.
