AI website monitoring that alerts you to restocks, price drops and page changes
Describe your monitoring goal in plain text and let the model work out what on the page matters, instead of writing selectors or regex.
Monitoring is driven by GPT-4 Vision, so the service can interpret page layouts and pick up meaningful visual and content changes.
Pick a single element on the page with your mouse, or watch for a keyword anywhere in the text, to cut noise from unrelated page churn.
Route notifications to the channels you already use, including email, SMS, Slack, Discord and webhooks, so alerts land where you will see them.
