# Duelpilot > A/B testing (Optimizely/VWO-class) run end to end by the customer's own AI agent over MCP. The agent installs one script tag, finds test ideas in GA4, designs variants with previews and real-browser checks, and monitors results with always-valid sequential statistics. A person approves every launch. Flat price per site, no AI credits.
