About Buy or Not
Buy or Not is a purchase decision helper that gives you an honest AI opinion whenever you're on the fence about buying something. So many things you want, but not sure you should actually hit "buy"? Just enter the product name and price in Buy or Not. The AI rates your purchase on a four-level scale — from Highly Recommended to Not Recommended — and delivers a candid, friend-like verdict, along with better alternatives when they exist. Key Features AI Purchase Advice Enter the product name, price, and any extra details, and the AI analyzes whether to buy on four levels: Highly Recommended / Recommended / Hold / Not Recommended. No dry lectures — just the honest, entertaining take you'd get from a good friend. Better Alternatives If there's a smarter choice than the item you're eyeing, the AI suggests it too. Free Consultation Tickets Start with 3 free tickets, and get one more automatically every day. Running low? Watch a short ad to earn extras. Purchase History Look back on past consultations by date, and share the results with friends. Personalized Advice Based on a simple profile, the AI tailors its advice to your spending style. Comfortable Experience Supports both dark and light modes, available in English, Korean, Japanese, and Chinese. When to Use It - When you want to stop an impulse buy - When you're torn between similar products - When you need an objective take on whether the price is fair - When you don't want buyer's remorse Note AI advice is for reference only. The final purchase decision is always yours.
