See what changed not just that something changed
changebrief monitors web pages and uses AI to tell you exactly what happened. No blurry screenshots. No red pixels. Just a clear sentence.
How it works
Three steps. No code.
Add a URL
Paste the page you want to monitor. Pricing page, terms of service, status page — anything.
We take screenshots automatically
A headless browser runs in the background and captures exactly how the page looks — every hour, day, or week.
AI tells you what changed
AI vision compares before and after, and sends a clear summary to Slack, Teams, or email.
Use cases
One tool. Dozens of high-value applications.
Competitor pricing
Know within hours when a competitor changes pricing, removes a free tier, or adds a new plan. React the same day instead of next quarter.
Regulatory changes
Monitor government agencies and regulators for policy updates, new rules, or changed requirements that affect your industry.
SaaS terms & contracts
Catch silent changes to terms of service, privacy policies, or SLAs from vendors you depend on — before your renewal date.
Hiring & strategy intel
Watch competitor career pages. When they start hiring ML engineers or enterprise sales reps, you know where they're heading next.
Supplier & MAP pricing
Track supplier prices, wholesale catalogs, or MAP compliance across resellers. Catch price drops before your competitors do.
Your own site integrity
Detect accidental deploys, defacement, SEO spam injection, or broken layouts on your own pages — before customers see them.
Simple pricing
Start free. Upgrade when you need more.

Frequently asked questions
How is changebrief different from Visualping?
Visualping shows you an image with red pixels where something changed. You have to figure out what it means yourself. changebrief sends the screenshot pair to AI vision and returns a sentence describing exactly what changed — "Price increased from $29 to $39/mo" instead of a red blob.
How accurate are the summaries?
We use state-of-the-art vision AI that understands what's displayed on a web page — prices, buttons, text, layouts. It compares two versions of the same page and describes exactly what changed in plain language. The importance score (1-10) helps you filter noise from signal.
Can I monitor pages behind a login?
Yes! You can configure cookies and HTTP headers per URL. This makes it possible to monitor pages that require authentication, such as internal dashboards or customer portals.
Where is data hosted?
All data is stored within the EU. Screenshots are encrypted at rest. We never share data with third parties beyond what's required for the AI analysis.
