TrendRadar
Scan social media and communities to detect trending products before they peak — then act on them with BuyWise and CouponClaw.
TrendRadar monitors 小红书, 微博, Reddit, Google Trends, and Product Hunt in real time. It assigns a trend direction (↑↑ surging / ↑ rising / → stable / ↓ cooling) and a commercial signal to each item, so you know whether to buy now, wait, or skip.
What TrendRadar does differently
Most tools show you what's already popular. TrendRadar shows you what's about to peak — so you can get the best price before demand drives it up, or avoid buying into something already fading.
It is the upstream signal source for the entire ecosystem:
- Feed trending products into BuyWise for price and review analysis
- Feed trending stores into CouponClaw for coupon and cashback stacking
- Daily briefing surfaces the top 3 most commercially interesting trends each morning
