Frequently Asked Questions

How do I compare two texts?

Paste or type your original text in the left box and the modified text in the right box. Click the "Compare" button to see the differences highlighted in color.

What do the colors mean?

Green highlights indicate text that was added, red highlights show text that was removed, and yellow highlights indicate modified lines. Unchanged text has no highlight.

What's the difference between line and character mode?

Line mode compares texts line by line, which is better for code or structured content. Character mode compares character by character, which is better for finding small changes within lines.
