PageVigil — AI page monitor & change alerts

Stop refreshing pages. Stop drowning in false alerts. PageVigil watches any element on any web page — a price, a job board, a stock badge, a contract clause — and tells you when something meaningful changes. Not when an ad rotates. Not when a timestamp ticks. When the thing YOU care about actually changes. HOW IT WORKS 1. Click the PageVigil icon on any page, then click the element you want to watch. No selectors, no code. 2. Say when to alert you, in plain English: "price drops below 50", "mentions PhD funding", "back in stock" — or leave it blank for any meaningful change. 3. Our servers check on your schedule (15 minutes to daily). Your computer can sleep; monitoring never does. WHY PAGEVIGIL ★ AI noise filtering — on a typical monitored page, most detected changes are ads, session IDs, and timestamps. PageVigil's AI understands your condition and suppresses the noise. Every suppressed change stays inspectable in your log — trust, but verify. ★ Plain-English conditions — your words become the monitoring rule. Thresholds are evaluated exactly; nuanced conditions like "back in stock" are judged by AI against the real change. ★ Self-healing monitors — when a site redesigns and the element moves, PageVigil re-finds it from its fingerprint and keeps watching. No silently dead monitors. ★ JavaScript pages included — dynamic listings and single-page apps are rendered in a real headless browser. ★ Alerts where you live — email, Telegram, or Discord, with the before/after values inline. ★ Flat pricing — no confusing "checks" or "credits". Free: 3 monitors, daily checks. Pro ($15/mo): 25 monitors, hourly, AI filter. Power ($29/mo): 100 monitors, 15-minute checks.
