Step 3 User review sentiment analysis dashboard

Problem

When new products like Galaxy Buds4 launch, audio accessory companies (cases, ear tips, charging docks) need to quickly capture complaints and needs from user reviews to plan new products. Manually analyzing reviews across Coupang, Naver, and Amazon takes 2-3 weeks per product, creating opportunity costs as competitors gain first-mover advantage.

Solution

Automatically collects multi-channel reviews for specific audio products and provides a dashboard with sentiment analysis by category (fit, sound quality, battery, noise cancellation, etc.). (1) Automated review collection from Coupang/Naver/Amazon, (2) Positive/negative/neutral sentiment classification by category, (3) Automatic extraction of complaint keyword trends and accessory opportunity points.
