Recurring monitoring
Monitor the source page with PageDog.
Use the free diff for a one-off review. PageDog checks the selected page area on a schedule and records the next text change.
How it works
Compare changes by words or lines.
Paste
Add the old and new copy directly, or open a plain text, Markdown, or HTML file.
Review
Compare by words or lines and ignore spacing or capitalization when those differences do not matter.
Share
Copy or download the result locally, or deliberately publish an unlisted review link.
Questions
Text diff FAQ
Is my text uploaded?
Not while you compare or download. Text leaves the browser only when you explicitly choose Share result, which creates an unlisted recipient link.
Should I compare by words or lines?
Words works best for page copy, prices, policies, and short paragraphs. Lines is clearer for lists, release notes, structured content, and copied source files.
Are shared comparisons searchable?
No. Shared comparisons use a long random URL and are marked noindex. Anyone with the link can read the text, so remove secrets before publishing.
