I built it for myself first.
Price tracking is deceptively hard. Sites change their HTML. Bot detection blocks naive scrapers. Currency conversions drift. Every retailer has different anti-scraping defenses.
I shipped AIPriceCheck as my own product at aipricly.com — go try it on a real product URL. If you want a private build tuned for your specific retailers or feature set, that's the custom-build path on the right.
