Meaningful monitoring
Describe the value, status or condition that matters instead of watching every visual change.
Website change alerts
Get an alert when the part of a webpage you care about changes.
SeeWhen monitors the condition you describe, so you can follow a changing page without repeatedly opening and refreshing it yourself.
What SeeWhen can do
Plain-language setup
Tell SeeWhen what you are waiting for in normal language.
Automatic checks
The Watch runs in the background and updates its schedule based on the page and recent activity.

- 1
Choose the page
Paste a public page that contains the information you want to follow.
- 2
Describe the change

- 3
Let SeeWhen monitor it
SeeWhen checks the page and alerts you when your condition is met.
Questions
Can SeeWhen monitor a webpage for changes?
Yes. You can ask SeeWhen to monitor a meaningful value or condition on a public page, or to notify you when the relevant content changes.
Will I be alerted for tiny layout changes?
SeeWhen is designed around conditions and meaningful page content rather than blindly notifying you about every pixel or formatting change.
What pages are supported?
Many publicly accessible HTML webpages can be monitored. Pages requiring a login or sites that block automated checks may not work reliably.
