Shows an LLM-driven scraper that replaces fragile XPath/CSS logic with prompted visual element selection using Chromium hooked to GPT‑4o and frameworks like Firecrow/browser‑use; an old Scrapy/Playwright pipeline takes ~30 minutes, the LLM agent pulls ~200 LEGO products in ~3 minutes. Uses rotating IPs via a 5–10 phone cluster, mentions CAPTCHA solvers at ~$0.002 per solve and built LinkedIn automation that bulk‑messages/profiles leads; demos run, produce CSV/JSON and handle simple CAPTCHAs.
