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
GPT-4o Vision compares before and after, and sends a clear summary to Slack, Teams, or email.
Use cases
Three common scenarios. One solution.
Competitor monitoring
Know immediately when a competitor changes pricing, features, or positioning. React the same day instead of next quarter.
Vendor terms
Get notified about contract changes, new policies, or pricing updates from your vendors — before they affect you.
Status pages
Monitor uptime status for your critical services. Know about outages before your customers notice.
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 GPT-4o Vision and returns a sentence describing exactly what changed — "Price increased from $29 to $39/mo" instead of a red blob.
Which AI model is used?
GPT-4o with Vision from OpenAI. The model understands what's displayed on a web page — prices, buttons, text, layouts — and can describe the difference between two versions of the same page.
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.
