Every other AI sales widget on Shopify uses the same pattern: a small floating button in the corner. The visitor has to notice it, decide to click it, and type a question. Three steps of friction before the conversation starts. Most visitors never take step one.
Remplace uses a notification bar that appears at the bottom of the page when a buying signal is detected. The agent reaches out first. The visitor just reads the message and decides whether to reply. This is the fundamental difference between a proactive agent and a passive widget.
The bar reads the store's primary color on first load and adapts its background, text color, and accent automatically. No manual configuration by the merchant. A jewelry store gets dark purple. A skincare brand gets sage green. A coffee shop gets amber. The widget looks native to the store it is installed on.
A visitor who sees a chat bubble decides in half a second whether they need help. They usually decide they do not. The sale is lost not because the product was wrong, but because no one stepped in during the decision window. The bar does not wait for that decision. It appears at the exact moment a buying signal fires with a message that matches what the visitor is thinking.
