We're on a mission to empower shoppers with transparency and help you make smarter purchasing decisions. SmartPrice Guard was born from a simple frustration: fake discounts that trick consumers into thinking they're getting a great deal.
In 2024, our founder noticed a troubling trend on Amazon: products would suddenly spike in price by 30-50%, only to go "on sale" days later, claiming massive discounts. The reality? Many of these "deals" were actually more expensive than the original price just weeks before.
This deceptive practice, known as price manipulation or fake discounting, costs consumers millions of dollars every year. We decided it was time to do something about it.
SmartPrice Guard was created to level the playing field. We built a powerful browser extension that analyzes real price history data, detects fake discounts, finds cheaper alternatives, and summarizes thousands of reviews in seconds—all to help you make informed decisions and save money.
Our mission is simple: to help consumers save money by providing transparent, accurate, and actionable shopping intelligence. We believe everyone deserves to know the real value of what they're buying.
We're committed to:
We never collect personal information. All your data stays on your device, and we use secure server-side processing for sensitive operations. Your privacy is not for sale.
SmartPrice Guard will always be free. We believe saving money shouldn't cost money. No premium tiers, no hidden fees, no credit card required—ever.
Every feature we build is designed with one question in mind: "Does this help users save money?" If it doesn't, we don't build it. Simple as that.
We use cutting-edge AI and data analysis to provide insights that weren't possible before. Our fake discount detection algorithm analyzes 60 days of price history in real-time.
SmartPrice Guard uses a combination of advanced technology and trusted data sources to provide you with accurate shopping intelligence:
We partner with Keepa to access real historical price data from Amazon. Our algorithm analyzes 60 days of price history to detect when prices were artificially inflated before a "sale." If we see a price jump of 20% or more followed by a discount, we flag it as a potential fake discount.
Using SerpAPI, we search across multiple retailers including Walmart, Target, Best Buy, and others to find the same or similar products at lower prices. We only show alternatives from trusted retailers with good reputations.
Our AI reads hundreds of product reviews using OpenAI and Google Gemini to identify common complaints, praises, and issues. This saves you hours of reading through reviews and highlights the most important information about product quality, durability, and common problems.
All analysis happens in under 2 seconds on our optimized backend servers. We never store your browsing history or personal data—everything is processed securely and immediately.
Unlike many browser extensions, we don't collect or sell your personal data. We don't track your browsing history, and we don't store any information about you. Your privacy is our priority.
We've optimized our backend to deliver complete price analysis, alternatives, and review summaries in under 2 seconds. No waiting, no loading screens—instant insights.
Our fake discount detection has a 95%+ accuracy rate. We use real data from trusted sources, not estimates or approximations. If we're not confident, we won't show it.
We're constantly updating our algorithms and adding new features based on user feedback. Our team is committed to making SmartPrice Guard better every single day.
Every time you use SmartPrice Guard and avoid a fake discount, you're not just saving money—you're sending a message to retailers that consumers value transparency.
