Working on my next tool: Page Alert – get notified when anything on a web page changes

Hi everyone 👋

After building Crypto Price Alert, I kept running into the same problem outside crypto: checking the same websites over and over. Prices, apartment listings, job offers, hotel availability, government announcements.

So I built Page Alert, a browser extension for Chrome and Edge:

🎯 Select any element on a page (a price, a status, a value) and get notified when it changes

📋 Watch a whole list and see when new items appear

✨ Smart AI mode summarizes what actually changed in a block of text

📱 Alerts sync to your phone with a pairing code, no account needed

No account, no tracking. There's a free plan.

🎬 See it in 35 seconds: Link

It's already live in the Chrome Web Store and Edge Add-ons, and I'm preparing a proper launch here on Product Hunt.

Before that, I'd love your honest feedback:

- What would you monitor with a tool like this?

- What would stop you from installing it?

Thanks for reading!
