Hawk - AI Price Monitor

Hawk — AI Price Monitor is an intelligent price tracking agent built for the Bright Data AI Agents & Web Data Hackathon. It combines real-time web scraping, AI-powered analysis, and trend forecasting into a single, easy-to-use dashboard. Users can search for any product, select it from the results, and immediately start tracking prices across major retailers such as Amazon, Walmart, Best Buy, eBay, and Target. Hawk scrapes live pricing data using Bright Data's Web Unlocker, extracts prices from raw HTML using multi-pattern parsing, and stores a full 14-day price history per product. On top of the scraping layer, Hawk runs AI analysis powered by a local LLM (DeepSeek via Ollama). For every tracked product, it generates a best deal recommendation, a buy-now-or-wait signal, competitive market insight, and a suggested alert price. Users can also set price alerts and get notified when a product drops below their target. The forecasting module analyzes historical price patterns — detecting rising, falling, volatile, or stable trends — and produces a 7-day price range forecast. An interactive chart visualizes the full price history per store. Hawk also features a built-in AI chat assistant scoped strictly to pricing questions, allowing users to ask things like "Should I buy now?" or "Where is it cheapest?" and get concise, data-driven answers. The stack: FastAPI backend, React + Vite frontend, Bright Data Web Unlocker for scraping, DeepSeek R1 via Ollama for local AI inference, and SerpAPI for product search.
