About TextDiff
Professional comparison, without the upload.
TextDiff makes additions, removals and exact wording changes easy to review for everyday prose, business documents and technical text.
Designed to stay privateNo account, uploads, database, AI or saved text history.
How it works
A structural diff aligns inserted and deleted lines, then refines changed regions at word or character level. Comparison rules let you decide whether whitespace, case, punctuation, accents and Unicode representation matter.
Built for real review
Use side-by-side, inline, focused, change-list and statistics views; navigate every change; open local files; and generate reports without sending document content to a server.
An MJ Apps tool
TextDiff is a focused privacy-first utility: no account, no document library and no distractions from the comparison itself.
