PageAlert

PageAlert lets users watch any web page for specific information without writing code or defining CSS selectors. A user pastes a URL and describes the desired condition in plain English—such as a price ceiling, stock availability, or a job title—and the system’s AI parses the page, extracts relevant items, and tracks changes over time. When the condition is met, alerts are sent instantly through email, Telegram, or Discord.

The service targets individuals and teams who need to keep tabs on product prices, inventory levels, new listings, real‑estate offers, or job postings across diverse sites, including e‑commerce stores, classifieds, and auction platforms. Because the monitoring relies on AI‑driven extraction rather than static selectors, it continues to work even when page layouts change.

PageAlert offers a free tier with a limited number of monitors and six‑hour check intervals, and paid plans that increase monitor count, frequency, and data retention while adding multiple notification channels. The tool is positioned as an experimental, code‑free solution for automated web‑based alerts.
