EcoCart AI

说明与用途

EcoCart AI 是一个 Chrome 扩展，实时评估产品的环境影响，推荐更绿色的替代品，并支持一键购买碳抵消。

问题

Online shoppers lack instant visibility into the environmental impact of products, making eco-friendly choices difficult.

结果

EcoCart AI delivers an Eco‑Score within 2 seconds of opening a product page, offers greener alternatives, and facilitates one‑click carbon offset purchases, improving the sustainability decision‑making process for shoppers.

工作流

• 1. User installs EcoCart AI Chrome extension.
• 2. Extension injects a content script that observes the product page DOM using MutationObservers until fully loaded.
• 3. Script extracts product details (specs, brand, shipping distance).
• 4. Data sent to backend API hosted on Vercel.
• 5. Backend calls Gemini Pro API to scrape and summarize relevant product information and corporate sustainability reports.
• 6. AI generates a structured JSON Eco‑Score and alternative product suggestions.
• 7. Backend caches results in MongoDB Atlas for future requests.
• 8. Frontend displays a slide‑out panel with the Eco‑Score, alternative options, and a one‑click carbon offset button.
