Frequently Asked Questions:

How do I interpret the highlighted results?

Our tool highlights the differences to make them easy to spot. Text highlighted in green indicates content that was added, while text highlighted in red indicates content that was removed. Unchanged lines are not highlighted.

Can I compare files instead of just pasting text?

Currently, our tool is designed for comparing text pasted directly into the input fields. For comparing entire files, you would need to open them, copy the content, and then paste it into the respective text areas.
