About Compare Text
Spotting what changed between two versions of a document, an email draft, or a block of code by eye is slow, especially for a long passage. This tool compares two texts side by side and highlights exactly what was added, removed, or changed.
Paste your original and revised text, and every difference is highlighted clearly. Everything runs locally in your browser.

Is this the same as your Compare PDFs tool?
