Text Compare
Paste two texts and see the differences highlighted: equal lines stay plain, removed lines are struck through, added lines are marked green.
How to compare two texts online
Enter the original text on the left and the revised text on the right, then click Compare. The tool aligns the texts line by line and highlights what changed, so you can review edits without eye-straining.
