I built an AI-powered website monitor that doesn't need CSS selectors — just point and click
got tired of writing CSS selectors every time I wanted to monitor a website for changes. so I built PulseWatch — it uses GPT-4o to analyze page screenshots and lets you just click on what you want to track.
when something changes you get a plain language summary like "price dropped from $1299 to $1099" instead of a raw HTML diff.
tech stack if anyone's curious:
- .NET 8 backend
- Flutter for web + iOS + android
- PostgreSQL + Redis
- Railway + Vercel
- Firebase for push notifications
free tier available, would love feedback from other devs
