About Text Compare

Compare two blocks of text and highlight the differences between them. Text and data chores like formatting, validating and converting are small tasks that interrupt real work.

Everything runs locally in your browser using standard web APIs — nothing is uploaded, queued, or stored on a server. Your files never leave your device, so there is no privacy trade-off, no file-size limit imposed by an upload, and no waiting for a round trip. It also means the tool keeps working on a slow or intermittent connection, and there is nothing to delete afterwards.
