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.

You shouldn't have to interpret screenshots. AI does it for you.
"Something changed... but what?"
Acme Corp removed the "Free for 14 days" button and raised the Pro price from $29 to $39/month.
New feature "AI Insights" added to the Enterprise plan.
Crystal clear. Straight to Slack.
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.
Features
What sets changebrief apart from pixel-diff tools.
AI-powered summaries
GPT-4o Vision understands what's shown — prices, buttons, text. Not just pixels.
Importance score (1-10)
Filter out noise. Only get notified about important changes — pricing, features, terms.
Slack, Teams & Discord
Notifications straight to the channel your team already uses. Plus PagerDuty, Jira, and webhooks.
Scheduled monitoring
Every hour, day, or week. You decide. We run in the background.
Screenshot history
See exactly how a page looked a day, week, or month ago. Visual timeline.
REST API & Webhooks
Connect to Zapier, Make, n8n, or build your own integration. JSON payload on every change.
Simple pricing

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.
