Approving and dismissing visual changes

Accept an expected change as the new baseline, or dismiss noise so it stops re-alerting.

baseline

Quick answer#

Every visual alert has Approve (make this the new baseline) and Dismiss (ignore this one, keep old baseline). Approve when the change was intentional.

What it does#

Approve — replaces the baseline with the new capture; future runs compare against it

Dismiss — clears the alert without changing baseline; next different capture will alert again

Snooze — silences the monitor for a chosen window (useful during redesigns)

Where to find it in Lemwatch#

Alerts inbox → click a visual change → Approve / Dismiss / Snooze.

How to use it#

Open the alert to see the side-by-side diff.

If the change was intentional (new hero, updated price) → Approve.

If it was noise (ad rotation, one-off flicker) → Dismiss and consider adding an ignore zone.

If you're mid-redesign → Snooze for 24–72 hours.

Approved captures show a badge in the timeline.

FAQ#

Can I approve in bulk?#

Yes — filter the inbox to "visual change" and use the bulk-approve action.

Does approve trigger a webhook?#

No. Only new detections fire webhooks.
