Monitor Any Page With AI
Get a plain-English alert the moment something changes — not a wall of text to read through.
Point WebDoppler at any page. Describe what matters to you. It watches, extracts, and tells you only when there's something worth knowing.
How WebDoppler Works
Points and Watches
Aim WebDoppler at any page — a filing index, a pricing page, a notice board.
Reads and Decides
It figures out what actually matters and ignores the rest — no noise, no false alarms.
Extracts and Structures
Pulls out exactly the data you described, the same way, every single time.
Alerts and Delivers
A clean notification lands wherever you work — webhook, email, SMS, or Slack.
Less noise. Less manual checking. More signal.
Catch what matters, skip the noise
WebDoppler ignores ad rotations, footer timestamps, and cookie banners — it only speaks up for real changes.
No more reading raw HTML diffs
Get the actual data — a price, a deadline, a filing — not a wall of markup to interpret yourself.
Set it up once, in plain English
Describe what you're looking for. No regex, no CSS selectors, no schema to maintain.
Works on the hard pages too
Cookie walls, embedded tax tables, JavaScript-heavy sites — handled automatically.
Plugs into how you already work
Webhook, email, SMS, or Slack — your choice, configurable per monitor.
Built on a full retrieval engine
Not a single-purpose monitoring tool — WebDoppler runs on the same engine that powers Gyrence's crawling and extraction API.

}What makes WebDoppler different
Most monitoring tools treat every page the same. WebDoppler is built on Gyrence's full retrieval engine, which means it handles the pages that break simpler tools.
| Capability | WebDoppler | Typical monitoring tool |
|---|---|---|
| Ignores pagination & calendar loops automatically | ✓ | — |
| Skips mirrored content across domains (near-duplicate detection) | ✓ | — |
| Reads inside embedded iframes (tax tables, IR platform content) | ✓ | — |
| Dismisses cookie banners & terms walls before capture | ✓ | Some plans |
| Plain-English extraction — no CSS selectors or regex | ✓ | Limited |
| Webhooks included on every plan | ✓ | Often gated to top tier |
| Built on a general-purpose retrieval API | ✓ | — |
"Typical monitoring tool" reflects common patterns across general-purpose change-detection products as of 2026.
Common questions
How long does setup take?
About 60 seconds per monitor. Paste a URL, describe what to capture in plain English, approve the preview extraction, and you're live. Bulk CSV upload is available for registering many URLs at once.
How often does WebDoppler check a page?
Per-monitor interval — Hourly or Daily by default. Each check is 1 credit against the same pool as Fetch, Gyre, and Extract. No separate monitoring product, no per-site markup.
How are webhook alerts delivered?
A signed POST to your endpoint the moment an anchored change is detected, with the diff and any extracted_fields attached. Webhooks are included on every plan — alongside email, SMS, and Slack channels.
What if my webhook endpoint is down?
Failed deliveries retry with exponential backoff. The full run history and alert payloads remain available in the console so nothing is lost.
Stop checking the page by hand
Register your first monitor in the console — describe what you need, approve the preview, done.
