Trendier AI Library is a subscription-based trend-intelligence platform for e-commerce market research. Built full-stack — frontend UI plus contributing to the backend API — it surfaces rising and emerging product trends through a browsable content system: trend discovery views, curated collections, category/tag browsing, and article-style posts with a slide viewer (free users get a 2-page preview before a subscription paywall). It also includes report/slide generation tools that turn aggregated product data into exportable PPT/PDF/XLS decks, plus account, billing, and organization management.
