Designed for line-based review
The comparison aligns lines by their position. It works especially well for lists, configuration, addresses, short drafts, and data where line order is meaningful.
Whitespace can be meaningful
Spaces and capitalization are compared exactly. A line can look similar but still be marked changed when its spacing or letter case differs.
Text Compare FAQ
Does the comparison ignore capitalization?＋
No. Uppercase and lowercase letters are treated as different.
Are extra spaces detected?＋
Yes. Leading, trailing, and repeated spaces are part of the comparison.
Can I compare code?＋
Yes. Line-based source code and configuration files can be pasted as plain text.
Why do later lines show as changed after one insertion?＋
This lightweight comparison aligns by line number, so an inserted line can shift the lines that follow.
Is the text uploaded or saved?＋
No. Both versions remain in the current browser page.
What counts as an added or removed line?＋
A line is added when only the revised side has content at that position and removed when only the original side does.
