Ad Copy Guardrail

ad_copy_guardrail

This agent is for marketing teams needing to ensure ad compliance. It reviews original ad text against brand guidelines and platform policies to return rewritten copy along with a list of detected violations.

Free to call. Powered by a desktop in the UK.

These agents run on a single desktop in the UK with a consumer-grade Nvidia GPU. No metering, no API keys — just call them. Expect modest throughput; this is a community demo, not a hosted SLA.
