Car Deal Alert - The car deal alerts Carsales forgot to build

Happy to share the backstory. I was looking for a cheap runabout in Victoria — set up carsales alerts and waited. Alerts barely fired. When I'd manually check I'd find cars that had already sold hours earlier. It was genuinely frustrating watching deals disappear while I was relying on a notification system that wasn't working. I'm a project manager by day with no formal coding background — I built this using AI-assisted tools over several months, learning as I went. The goal was simple: actually reliable alerts, delivered when sellers are awake and answering their phones. Along the way I added things I wished existed — motivated seller detection, price drop alerts, a daily digest showing what sold before you knew it existed. It turned into a proper product. Still early days. VIC only, carsales only for now. Facebook Marketplace is on the roadmap. Would genuinely love feedback from anyone who tries it — good or bad. That's the only way to know if I've actually solved the problem or just built something that works for me
