I built SaleSentry with Claude AI because I was tired of missing Steam sales. No browser, no emails—it sits in your system tray and pings you when a deal hits your target price or historical low. What makes it different: Auto-sync with your Steam wishlist. Light & fast: No heavy browser needed. Verified safe (0/70 on VirusTotal). Multi-language support (EN, JA, ZH, RU, FR). Give it a try! It’s 100% free.
