Questions

How can it tell what changed if you've never seen the page?

We compare the page as it is now with the copy the Internet Archive (the Wayback Machine) saved about a week, a month or a year ago, and explain the differences in plain English.

Is it really free?

Yes, with no sign-up. To stop it being misused there's a small daily limit per person.

Why does it say there's no earlier copy?

The Internet Archive doesn't save every page. Smaller or newer pages often have no copy. ChangeGist can start watching the page from today, so you'll know about every change from now on.

Can it email me next time the page changes?

That's what ChangeGist does: it checks the page on a schedule and emails you a plain-English summary whenever something important changes. Free for 3 days, no card needed.
