This repository scrapes AI-related subreddits in English and Chinese, then uses LLM APIs (DeepSeek R1 via OpenRouter, Groq) to analyze posts, summarize discussions, and rank trending topics. It incorporates multimodal capabilities including vision models for image analysis, YouTube transcript extraction, and web page scraping via Firecrawl. Reports are stored with MongoDB persistence for historical trend analysis and updated automatically with daily highlights, weekly comparisons, and monthly evolution tracking.
