NARAK helps marketing teams spot cultural concerns in South Korean ads before they go live. These concerns can come from hand gestures linked to online controversies, words that people interpret differently, or dates connected to sensitive historical events.

In May 2026, a coffee chain's CEO was fired after a promotion on a painful historical anniversary caused public criticism. Similar problems have happened across different industries, yet marketing teams can still miss these cultural connections.

Users upload a poster, add optional ad copy, and choose a publication date. NARAK researches real reports and past cases, then shows possible concerns with supporting sources. It can also highlight relevant parts of the poster and let teams test design changes.

Powered by Meta's Muse Spark 1.3, SAM 3.1, and Muse Image 1.0.

Built during the Meta Global AI Developer Hackathon, Oct 27 to Nov 4, 2026.
