ChangeGuard checks the web pages your work depends on, from rules and contracts to prices and competitors. When one changes, you see the words that changed, a short summary, and how much it matters.
Free for 5 pages. No card needed.
Checked on your schedule
Every page about once a day, and key pages as often as every hour from Starter up.
Words, look and documents
Every check compares the text and the screenshot, and looks for new PDF, Word and Excel documents the page links to.
Summaries written on our own systems
Your pages are not sent to outside AI companies.
No charge per person
From Team up, your whole team can log in for the same price.
How it works
Paste the web addresses, or upload a spreadsheet. Group them into sets: one for each supplier, regulator or competitor.
Choose how often to check: every few hours, daily, weekly or monthly, at a time that suits you. Click the parts of a page to ignore, or name the words to watch for.
Each check saves the page’s text and a screenshot, then compares them with the last version. It also spots any new PDF, Word document or Excel spreadsheet the page links to. A change that is only formatting is rated minor, and anything below the floor you set stays quiet.
You get an email that quotes the change: one per change, one per check, or a daily or weekly round-up. Each change comes with a short summary and a rating of how much it matters, and past versions are kept.
See a change
The old and new versions of a page, side by side, with the differences highlighted and a short note on what they add up to. Text that only moved is shown as moved, not as deleted and typed again. Drag the divider, or use the arrow keys.
Best Buy · Apple AirPods Pro 2 (USB-C)
Match it, undercut it or hold your price: you can only choose if you know.
How ChangeGuard helped
For compliance and legal teams
It marks the change on the page, says what it means, and lists the new documents.
Texas Secretary of State · Texas Register · Current issue (PDF)
State agencies propose their rules in it, and the time to comment counts from the issue's date.
How ChangeGuard helped
Stripe · Stripe Services Agreement
Half the warning before a fee goes up, in an agreement few people reread.

The product
Each set of pages shows how many changes are waiting, which checks failed, and what is new since you last looked. Open a change and the two versions are already side by side, and the whole queue can be worked through from the keyboard.
Cookie banners, chat widgets and footers are left out on their own. Point at anything else that never matters, then decide how big a change has to be before anyone hears about it.
Name the words or phrases a page is watched for, and it is flagged only when one of them turns up. Everything else on the page can change without a sound.
Each change comes with a short description in everyday words and a rating: likely minor or likely substantial. Decide what to open from the list.
Nobody gets email they did not ask for. One person can want a message for every change; another, a single round-up on Monday morning. Every message says what happened in its subject, quotes the change in its body, and has an unsubscribe link.
ChangeGuard reads pages with a real web browser, the way you do. It waits out “are you human?” checks, signs in where it has to, and repeats the clicks needed to reach the content.
A check of a page that blocks automated visitors counts as 5 instead of 1, because it needs a full browser session.
When a page you watch links to a new PDF, Word document or Excel spreadsheet, you hear about it. New documents from all your pages appear in one list. Each one opens from the site that published it.
Keep clients or departments in separate workspaces. From the Team plan up, invite as many people as you need, at no charge per person.
Who uses it
Rules, guidance and fee schedules change on agency sites without notice, and the people who answer for them find out from a client.
One set per regulator, the changed wording quoted in the email, and past versions kept.

How it is doneRules are proposed every week in the Federal Register, in each state's register and at city hall, and the time to comment starts the day they are published.
Watch each register's latest issue and each city's proposed rules, with every new one summed up.

How it is doneThe terms you agreed to are a web page the other side can edit. Service terms, privacy policies and data processing addenda move quietly.
The old and new wording side by side, the changed clause quoted in the email, and earlier versions to compare with.
aws.amazon.com · stripe.com · cloud.google.com
How it is doneSupplier price lists, plan limits and service status change between your reviews, and the invoice is the first you hear of it.
Ignore the parts that always change, keep the price table, and get a round-up on your own schedule.
aws.amazon.com · cloud.google.com · twilio.com
How it is doneCompetitors change prices, launch features and reposition without telling you. Their pricing page, changelog and careers page tell you first.
Screenshots compared as well as words, the clutter left out, and the exact line that changed.
notion.com · hubspot.com · zendesk.com
How it is doneThe page that matters sits behind a sign-in or a few clicks: a distributor's price list, a partner portal's terms, a tab that only opens when you click it.
Sign in and click through once; every check does the same before it reads the page.
How it is doneA release, a plugin update or a supplier's change quietly breaks a page nobody is looking at, and a customer finds it before you do.
Your key pages, compared word by word and screenshot by screenshot after every release.
How it is doneFilings, dockets, minutes and data releases land on their own timetable, and the index page is the only notice you get.
Watch the index page and be told when a new document appears, with its title and date.

How it is doneEach client has their own regulators, vendors or competitors to watch, and their own people who need to see the results.
One workspace per client on one plan, with the client's own people invited in.

Questions
Add the address of each page you want to watch, and choose how often it is checked. Each check compares the page with the version you last reviewed, marks the words that changed, sums up the change and rates how much it matters. You hear about it by email, one change at a time or in a round-up.
Almost any page you can open in a browser: an agency's notices, a vendor's terms, a price list, a competitor's product page, a page of search results, or a page behind a sign-in. The new PDF, Word and Excel documents a page links to are listed too.
Free is the trial. Five pages, checked about once a day, with the AI summary and rating, a weekly email digest and an instant alert on one page, for as long as you like. No time limit and no card.
One URL you are monitoring. Pages you archive stop counting and can be restored later. Every page belongs to a set, which is how you schedule checks and group alerts.
It depends on the plan: once a day on Free, and as often as every hour from Starter up. You set the schedule per set, from once a month up to your plan's limit, at a time that suits you. Every plan's monthly checks cover each of its pages about once a day, unless some of them block automated visitors: each look at one of those uses five checks.
One look at one page. A page that blocks automated visitors counts as five checks, because it needs a full web browser to get through.
The old and new versions of the page side by side with the differences highlighted, the two screenshots to compare, and a short summary in plain English with a rating of how much it matters. The email about it quotes the lines that arrived and the lines that went.
New PDFs, Word documents and Excel spreadsheets that a page you watch links to. Each one opens from the site that published it. A Word document or Excel spreadsheet over 100 MB is still reported when it appears, but it is too big to tell when it is re-issued.
By email. Every plan includes a round-up email (a digest), weekly on Free and daily or weekly from Starter, in your own time zone. For the pages that cannot wait there is an email per change, on one page with Free and more on each plan up, and a report after a set's scheduled check when something in it needs a look. From Business up, they can also go to Slack, Microsoft Teams or your own systems. The subject says what happened, the body quotes the change, and nobody receives email they did not opt into.
Once, when you sign up. Alerts go only to an address that has been confirmed, so a typo can never send your reports to a stranger. If mail to your address starts bouncing, alerts pause and the app tells you.
Yes, on the Business plan and up. Each change, and a report when a scheduled check finds something new, can go to a Slack or Microsoft Teams channel, or to your own systems by signed webhook, as well as by email. Your workspace's owner sets it up in Settings, Integrations.
Yes. Store a site sign-in once and every page on that site is checked signed-in. You can also record the clicks it takes to reach the content, and ChangeGuard repeats them on every check.
ChangeGuard uses a real browser and waits out the check. Blocks from DataDome and Cloudflare are recognised and waited out; Imperva and Radware blocks are recognised and often passed on a second attempt. Once a site has let it through, that is remembered. Each check of one of these pages counts as five.
Cookie banners, footers and chat widgets are left out on their own. For anything else, point at the parts of a page that always change and never matter and ChangeGuard ignores them. You can also set a minimum change size per page, set or workspace.
Yes. Give a page, a set or the whole workspace a list of words or phrases, and the page is flagged only when one of them appears in new text or in the name of a new document. Whole words, any capitalisation, and plurals made with -s or -es. The summary leads with the word that matched, and so does the subject of an email sent for that one change, unless the change is rated substantial.
Only people the workspace's owner invites. The owner holds the plan and invites people, admins set things up, and members review changes. Free is just you; from Team up there is no limit on people.
An account takes a minute: email and password, no card. Add a page, run the first check, then choose how often its set is checked.
