Web Alert (Website Change Monitor)- Notification when a website of your choice changes
- Visual difference of all modifications to a website detected (diff)
- Choose exactly which part or parts of a page to watch
- Check pages even behind logins, HTTP Authentications, form posts or long navigational sequences
-
On the options page, configure the device for checks, schedule, and notification actions, then save the monitor. Available notification actions depend on your subscription plan.
-
To inspect detected changes later, open the monitor preview in your Watchlist and review its change history.
Use the browser extension instead
On the target page, open the Distill extension menu and choose Monitor parts of page (also shown as Monitor Parts of Page in its Chrome guide). Select the region, inspect the preview, and save. Set the device, schedule, and notification action on the options page.

A monitor added through the web app defaults to a cloud device; one added through an extension or desktop app defaults to a local device.
Make the selection precise
Distill’s visual selector saves a selector for the content you choose. Visual selections use CSS by default in the web app and XPath in browser extensions. Distill also supports manually configured JavaScript selectors.
Include or exclude the right content
-
Use multiple selections when the information you need appears in separate regions.
-
Use expand or narrow controls to adjust the selected area. If a target is difficult to isolate, start with a smaller area and adjust from there.

Delete selections that do not belong in the monitor, or exclude nested elements inside a selected region.
Track matching text or an element property
A regular-expression text filter can extract only text that matches a pattern, such as numbers. You can also configure a monitor to track an element’s attribute or property rather than its text.
Fix a selection after saving
Open the monitor’s options and reopen the webpage selector to change an existing selection. The configuration view exposes selected and deselected elements and allows manual configuration changes. This is the place to adjust the target if the monitor later captures too much or too little.
Choose whether checks run locally or in the cloud
| Mode | What it means | Consider it when |
|---|---|---|
| Cloud | Checks run on Distill’s servers and can continue while your computer is off. | You want checks to continue when your own device is unavailable. |
| Local | Checks run through your browser or computer, which must be running for checks to take place. | You can keep the relevant device available and local execution suits your setup. |
Check intervals, plan accounting, proxy support, and supported page types can differ between local and cloud monitoring and may depend on the plan and client. Consult Distill’s current Local Monitor vs. Cloud Monitor documentation for the details that apply to your setup rather than assuming one interval or capability is universal.
Recommended Free Tools
Troubleshoot an inaccurate or unreliable monitor
-
The preview contains unrelated changes: Reopen the selector and narrow the area, remove extra selections, or exclude nested elements that are not part of the target.
-
The selection misses part of the information: Expand the selection or add another region. Review the preview before saving.
-
You need to track a number inside a larger block: Use a regular-expression text filter to isolate matching text, or target an element attribute or property when that is the value that matters.
-
Checks stop when you close your browser or turn off your computer: The monitor is running locally. Choose a cloud device if the checks need to continue while your device is unavailable; check the plan-specific limits for the cloud setup.

The option names do not match these steps exactly: Distill’s labels differ slightly across the web app and browser extension. Follow the equivalent partial-page selection flow for the client you are using.
Or skip the browser setup
For a one-off screenshot rather than ongoing change monitoring, ScreenshotNeo provides a screenshot API. It is not a replacement for Distill’s scheduled monitoring: use it when you need an image or PDF capture of a page.
For example, this cURL request saves a WebP screenshot of the target URL:

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpSee the ScreenshotNeo API documentation for setup and options. ScreenshotNeo removes cookie banners, popups, and chat widgets before capture; bot checks, blank pages, and failed loads are not billed. Its MCP server lets AI agents take screenshots. The Free plan includes 1,000 screenshots per month with no card, and paid plans start at $5 for 3,000. Learn about ScreenshotNeo or sign up for 1,000 free screenshots a month with no card.
