Remplace embeds a discreet bar on your store, not a chat bubble. When a visitor shows buying signals, the bar expands with a contextual message: returning from checkout, comparing products, or hesitating on a variant. The agent fires on the exact signal for each situation automatically. Every question it can't answer is logged with a suggested fix, so the agent improves over time. Your team can take over any live conversation from the dashboard at any time.
