Shop Smarter. Save More. Download Saysike.
Saysike is the browser extension that automatically finds you coupons, compares prices across the web, and alerts you when products get cheaper — all without ever manipulating what you buy.
The extension industry has a trust problem. We're fixing it.
You may have heard of shopping extensions that quietly replace affiliate links to claim commission they didn't earn — taking money from creators, misleading merchants, and eroding trust in the entire space.
Saysike is built differently. Our browser extension is fully open source, so anyone can read exactly what it does. We never inject affiliate links at the last second. We never track your browsing. We never collect data we don't need. What you install is what you get — nothing more.
How it works
Three steps. Zero effort.
Install the extension
Add Saysike to your browser in seconds. It's free, lightweight, and requires no account to get started.
Shop as normal
Browse any store you already use. Saysike runs quietly in the background — you won't even notice it's there until it finds something.
Save automatically
When we find a coupon, a cheaper price, or a price drop on something you're watching, a clean notification appears. One click and you save.
Everything you need. Nothing you don't.
Saysike is built around one idea: give shoppers every advantage, with complete transparency about how it works.
Instant Coupon Codes
The moment you land on a store checkout, Saysike automatically searches the entire internet for working coupon codes and applies the best one — saving you money without needing 5 other tabs.
Compare Prices Across the Web
Viewing a product? We scan over 1 billion listings to check if the exact same item is sold cheaper anywhere else online — across retailers, marketplaces, and independent stores.
Price Drop Alerts
Bookmark any product and we'll monitor its price history across millions of stores. The moment it drops, you get notified — so you never pay more than you have to.
Works Automatically
There's nothing to learn or configure. Install the extension and keep shopping as normal. Saysike silently works in the background and only speaks up when it finds you a better deal.
Zero Friction Checkout
Savings appear as a simple, unobtrusive popup. One click to apply — no redirects, no pop-up spam, no dark patterns. Your checkout experience stays clean.
Full Price History
See the price history of any product over time so you can spot whether a 'sale' is genuine or just a manufactured discount. Make buying decisions with full context.
Partner with a platform built on genuine value.
We're actively onboarding affiliate partners ahead of our launch. Because Saysike only surfaces deals to users who are actively shopping, every referral is genuinely earned — no last-click hijacking, no cookie stuffing, no tricks.
If you represent an affiliate network, merchant programme, or brand and want to be part of a transparent, consumer-first platform from day one — we'd love to hear from you. Find us on your affiliate network.
