TrendRadar

Scan social media and communities to detect product trends rising or peaking, helping time purchases or avoid declining items.

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

Trigger phrases

• "什么在爆"
• "最近什么在火"
• "小红书在推什么"

• "今日爆款"
• "热销商品"
• "trending products"
• "what's hot right now"
• "what's going viral"
• "trending on TikTok"
