  3. Click Compare to highlight differences.

Frequently Asked Questions

Does it compare word by word or line by line?

Both modes are available — switch between character-level, word-level, and line-level diff views.

Can I use this to compare code?

Yes — it works on any text including code. For complex code diffs, a dedicated diff tool like Git diff is more powerful.

How large can the texts be?

It handles large documents well. Very large files (100KB+) may slow down the comparison.

Can I copy just the differences?

Use the diff summary view to see only the changed lines without the unchanged context.
