How to Track Price Changes on Any Website
Whether you're monitoring competitor pricing, watching for deals, or tracking product availability, QuietDiff automates the process with AI-powered change detection.
Why Track Prices Automatically?
- Competitive intelligence: Know immediately when competitors adjust pricing
- Deal alerts: Get notified when products go on sale
- Dynamic pricing: Monitor how prices change throughout the day
- Stock tracking: Be alerted when sold-out items come back
How It Works
1. Extract Price
Point to the price on the page with a CSS selector or let AI find it automatically
2. Smart Alerts
AI filters noise (formatting, timestamps) and only alerts on real price changes
3. Take Action
Get email alerts, webhook notifications, or connect via API to your own tools
Example: Monitor Competitor Pricing
Let's say you want to track a competitor's pricing page:
- Create a monitor for their product page URL
- Define fields: Add "price" and "availability" fields
- Set check frequency: Hourly checks (paid tiers) or daily (free tier)
- Get alerts: Email notifications when prices change
Advanced: Multi-Product Tracking
Track multiple products or competitors by creating one monitor per URL. The free tier includes 10 monitors, and paid tiers support hundreds or thousands of monitors.
