Key features
Automatic Purchase Detection
Our browser extension monitors major e-commerce platforms and detects purchases automatically. No receipt uploads, no manual entry — it just works.
2-Second Reviews
We don't need an essay. Thumbs up or down. A few optional tags. Done. You've helped the next shopper and earned points in under 2 seconds.
Real Cashback
Points convert to real money. Cash out via PayPal, Venmo, or gift cards once you hit the threshold. 100 points = $1. No tricks, no expiration games.
Trust-Scored Reviews
Every reviewer has a trust score. Every review is tied to a verified purchase. The result: a review ecosystem that businesses and shoppers can actually believe.
For Businesses
Access genuine, incentivized product feedback from verified purchasers — not paid influencers. Understand what real customers think about your products, priced fairly and delivered honestly.
