How DetectaDeal's Tech Really Works to Spot Killer Deals

Most deal apps show you the same old listings. DetectaDeal is built differently. Here's a plain-English explanation of the actual technology behind how it finds, scores, and delivers deals to you.

Step 1: Continuous Price Scraping

The system watches thousands of products across Amazon India, Flipkart, and other platforms — every 30 minutes, around the clock.

Each scrape captures:

• Current listed price
• MRP (Maximum Retail Price)
• Seller name and rating
• Available stock
• Any active coupons or bank offers

This data is timestamped and stored. Over time, it builds a complete price history for every tracked product.

Step 2: Price Change Detection

Not every price change is a deal. The system compares each new price against the product's stored history.

A price change triggers a deal event only when:

• The new price is lower than the 30-day average by more than a set threshold
• The new price is at or near the product's all-time low
• The price drop is at least X% (configurable per category — electronics use a different threshold than books)

This filtering prevents alert spam. You don't get notified every time a product fluctuates by ₹10.

Step 3: AI Deal Matching

This is where DetectaDeal differs from simple price trackers. Once a deal event is detected, the AI layer checks whether the deal is relevant to specific users.
