Set Up Price Change Alerts in 5 Minutes
Never miss a price drop or surprise price hike again. This tutorial shows you how to set up AI-powered price monitoring for any product or service — no code, no browser extensions, no manual checking.
Why set up automated price alerts?
Prices change without warning — a competitor drops their plan price, a supplier raises wholesale costs, a retailer runs a flash sale. If you're not watching, you find out too late.
AI-powered monitoring checks every page you care about on a schedule and emails you a plain-English summary the moment something changes. No browser tabs to refresh, no manual spreadsheet updates.
Step-by-step setup
Create a free change-happens account
Sign up at change-happens.com — no credit card required. The free trial gives you full access to set up and test your first price alert.
Click "New Agent" and describe what you want to track
In plain English, tell the AI what to watch. Example: "Monitor the pricing page at store.com and alert me whenever any product price changes." You don't need to know anything about the site's structure.
Add the product or pricing page URL
Paste the URL of the page you want monitored — a retailer product listing, a SaaS pricing page, or any page that shows prices. You can add multiple URLs to a single agent.
Choose your check frequency
Select how often the AI checks for changes. Daily works well for most price monitoring. For fast-moving sales events, you can increase the frequency.
Activate and receive your first alert
Turn on the agent. The next time the AI detects a price change, you'll get an email digest explaining exactly what changed — which product, old price, new price — in plain English.
Example monitoring prompts
"Monitor this product page and alert me if the price drops below $200 or if a sale or discount is added."
"Check the pricing page at competitor.com daily. Tell me if any plan prices change, new plans are added, or the free tier is modified."
"Monitor the pricing table at supplier.com. Alert me any time a price increases or decreases by more than 5%."

Frequently asked questions
Does this work for any website? +
Yes. change-happens monitors any publicly accessible webpage — retail product pages, SaaS pricing pages, subscription services, airline fares, and more. If you can view it in a browser, the AI can monitor it.
How quickly will I be notified of a price change? +
Alerts are sent in your next scheduled digest after the change is detected. With daily monitoring, you'll typically know within 24 hours. You can increase check frequency if you need faster alerts.
Can I monitor multiple products at once? +
Yes. Add multiple product URLs to one agent, or create separate agents for different categories. One agent can cover an entire product category or competitor price list.
Will minor formatting changes trigger false alerts? +
No. The AI understands context — it ignores layout tweaks, ad changes, and currency formatting variations. It alerts you only when an actual price value changes.
Can I track price drops AND price increases? +
Yes. By default the AI alerts you to any price change. You can refine your prompt to say "only alert me if the price drops" or "alert me if the price increases by more than 10%" — the AI will follow your instructions.
