Finding the best time to buy no longer depends solely on luck or waiting for sales like Black Friday. Artificial intelligence has completely transformed the way consumers monitor prices, detect discounts, and compare products in real time.
This shift aligns with the evolution of digital commerce. Recent reports on consumer automation published by McKinsey show that more and more users are employing smart tools to optimize purchasing decisions and save time during the search process.
In this article, we explain the best tools for creating your own AI-powered price tracker, how to set up smart alerts, and what tricks to use to always buy at the best possible price without needing to know how to program.
The best tools for monitoring offers without knowing how to program
1. Keepa and CamelCamelCamel: The classics enhanced with predictive intelligence
Keepa and CamelCamelCamel remain two of the most popular platforms for analyzing product price history, especially on Amazon. Their main advantage is that they allow you to view:
- Price increases and decreases.
- Historical evolution.
- Real discounts.
- Moments of greater volatility.
This helps avoid fake deals or inflated discounts before sales events. In addition, the new smart tracking features allow you to receive automatic alerts when a product reaches your desired price. These are especially useful for technology, gaming, appliances, and high-value purchases.
2. Microsoft Copilot and Google Gemini: How to ask them to “monitor” a product for you
AI-powered assistants are also starting to be used as personalized purchase trackers. While they don’t completely replace specialized platforms, they can help you:
- Compare models.
- Summarize reviews.
- Identify alternatives.
- Analyze price differences.
- Automate frequent searches.
For example, you can order:
“Looking for a price drop for the iPhone 16 Pro below 1,000 euros”
Or also:
“Compare me current deals on gaming laptops with RTX 5070 and 32GB of RAM”
The biggest advantage is contextual conversation. AI understands exactly what you’re looking for and can filter recommendations much faster than a traditional comparison site. This type of assistant is part of the growth of so-called “AI Shopping Assistants,” a trend that major tech companies are already integrating into their search and productivity ecosystems.
3. Browser AI: The extension that automatically extracts prices from any website
Browser AI takes automation a step further. This tool allows you to extract prices, changes, and data directly from web pages, even if they don’t have an official alert system. In practice, it works like a small automated agent that monitors pages, detects changes, and notifies you when a relevant modification occurs.
It is especially useful in:
- Small marketplaces.
- Specialty stores.
- Limited items.
- Hardware.
- Hard-to-find products.
4. Karma (formerly Shoptagr): The assistant that organizes your desires and waits for the discount
Karma has become a favorite tool for users who buy fashion, home decor, or lifestyle products. It works very simply: you save products, create lists, and the platform automatically monitors price changes, stock levels, and promotions.
AI is especially helpful in prioritizing important discounts, urgent alerts, and products with a high probability of selling out.
In addition, it integrates multi-device tracking, so you can save items from your mobile phone or browser and receive alerts at any time.
Step-by-step guide: How to set up your first “Purchasing Agent”
Step 1: Define the product and the “target price”
The most common mistake is monitoring products without a clear idea of how much you’re actually willing to pay. Before setting up alerts:
- Define a maximum budget.
- Check the price history.
- Detect what the actual minimum price usually is.
For example, a laptop that currently costs €1,400 might regularly drop to €1,150 during specific promotions. That information is much more useful than a simple temporary price reduction.
Step 2: Set up smart alerts on your mobile or email
The key to these systems is automating the tracking. Most tools allow you to receive push notifications, emails, browser alerts, or real-time notifications.
To avoid being overwhelmed with unnecessary notifications, it is recommended to activate alerts only for priority products, relevant discounts, or important stock changes.
Step 3: Price History: Learning to Read Trend Charts
Not all deals are truly good. Historical charts allow you to identify inflated prices before sales, periods when prices drop the most, or gradual upward trends. Learning to interpret these charts is what truly transforms an automatic alert into a smart buying strategy. In many cases, waiting a few days can make a difference of hundreds of euros.
Conclusion: Start saving today with your digital detective
AI is changing the way we shop online. There’s no longer a need to constantly check online stores; today, any user can create their own smart tracker.
Tools like Keepa, CamelCamelCamel, Karma, and Browser AI make searching for discounts a much more automated and efficient process; while programs like Copilot and Gemini are starting to act as true shopping assistants.
In an environment where prices are constantly changing, having an AI-powered copilot can make the difference between impulse buying and buying at the perfect moment. The new way to save isn’t about searching more, but about letting technology find the best deal.
