Show HN: PulseWatch – AI-powered website change monitoring with visual selectors

https://pulsewatch.watch
2•KaracaTR•1h ago
I built PulseWatch as a solo dev because I was tired of writing CSS selectors to monitor websites for changes.

It uses GPT-4o to analyze page screenshots and suggest what to track — just point and click. When something changes, you get a plain-language summary instead of a raw diff.

Tech stack: .NET 8, Flutter (web + iOS + Android), PostgreSQL, Railway + Vercel.

Free tier: 2 monitors with daily checks.

Demo: https://youtu.be/2SKgV4QqtNg

Happy to answer any questions!
