See what changed
Every check is kept. Open a task to see its history, then open a check to compare it with the one before, read the AI summary and go through each change.
A task’s history
In Tasks, click a task’s row. The panel that opens starts with the latest check, a chart of the last 30 days (checks, alerts sent and failed checks) and the task’s Recent alerts. Under them, Last checks lists every check, newest first, with what it found, how much changed, when and its status. A run of checks that found no change is folded into one line; click it to open the run.

| Status | Meaning |
|---|---|
| Initial check | The first check, which records how the page looked when the task started. |
| Change, no alert | Something changed, but it didn’t meet the threshold or your Notify me when rule, so no alert went out. |
| Alert sent | The change met the task’s criteria and alerts went out. |
Use the sort and filter buttons above the list to narrow it, or CSV to download it. Changes your team flagged show their flag and comment count; hover over a change to flag or hide it from the row. Once something is flagged or hidden, filters for Flagged, each flag and Hidden appear above the list.
