How it works
Three clicks to a watchful eye
No selectors, no scripts, no scraping toolkits. If you can click it, you can watch it.
Point at anything
Click the PageVigil icon on any page, then click the element you care about — a price, a headline, an availability badge. Done.
Say when to wake you
Type it like you'd say it: drops below 50, mentions PhD funding, back in stock. Or leave it blank for any meaningful change.
We watch. AI filters.
Our servers check on your schedule — every 15 minutes to daily. Rotating ads, timestamps and cookie banners are silently ignored.
On a typical monitored page, five out of six detected changes are noise — ads, timestamps, session IDs. Traditional monitors forward all of them. PageVigil forwards the one that matters.
Every suppressed change stays in your log. Trust, but verify.
Why PageVigil
Built to be trusted
An alert is only useful if you believe it. Everything in PageVigil is designed around that.
Meaningful-change AI
Every alert says exactly what changed — “Price dropped from $89.99 to $67.00” — and every suppressed change remains inspectable. Nothing is hidden behind the filter.
Self-healing monitors
Sites redesign. PageVigil keeps a fingerprint of your element and re-finds it when the page structure changes — monitors heal instead of silently dying.
Alerts where you live
Email, Telegram, or Discord, with before-and-after values inline. Act on the alert without even opening the page.
Plain-English conditions
Your words become the rule. Numeric thresholds are evaluated exactly; nuanced conditions like “back in stock” are judged by AI against the actual change.
JavaScript pages included
Dynamic listings and single-page apps are rendered in a real headless browser — monitored just as reliably as static pages.
Honest scheduling
Checks run server-side on a fixed cadence — your laptop can sleep. A health badge on every monitor tells you it's alive and well.
Pricing
Flat, simple, no credit math
Other monitors sell you confusing “checks” and “credits”. PageVigil sells you monitors. That's it.
FAQ
Questions, answered
How is PageVigil different from other website change monitors?
Most monitors alert on any pixel or text change, so your inbox fills with rotating ads, timestamps, and cookie banners. PageVigil runs every detected change through an AI filter that understands what you asked for — you only hear about changes that actually matter, and every suppressed change stays visible in your log so you can verify the filter's judgment.
Can I really write conditions in plain English?
Yes. Type conditions like “price drops below 50”, “mentions PhD funding”, or “back in stock”. PageVigil compiles your words into a monitoring rule once; exact conditions like thresholds are then evaluated deterministically, and nuanced ones are judged by AI against each change.
What happens when a website redesigns and monitors break?
PageVigil stores a fingerprint of the element you picked — tag, attributes, and text. When a redesign breaks the original selector, the monitor re-finds your element from the fingerprint and heals itself automatically. No dead monitors, no manual re-picking.
Does it work on JavaScript-heavy pages?
Yes. Pages that render content with JavaScript are checked in a real headless browser, so single-page apps and dynamic listings are monitored just as reliably as static pages.
Is there a free plan?
Yes — 3 monitors with daily checks and email alerts, free forever, no card required. Paid plans add more monitors, faster checks, and the AI meaningful-change filter.
Where do alerts arrive?
Email, Telegram, or Discord — each alert includes a one-line summary of what changed plus the before and after values.
