ChangeChecks lets you compare text, images, PDFs, Word documents, spreadsheets, and code — all in one place, all in your browser.
Every comparison starts with a plain-English summary: how many things changed, where, and how much. No more reading a wall of highlighted text trying to find what matters.
Your files never leave your device. Drop in a sensitive contract or a confidential draft without worrying about where it ends up.
Free to use. No signup. No download. No watermarks.
A Pro tier is on the way with AI-powered explanations of what changed and why it matters — going beyond highlighting differences to telling you what they actually mean.
