AdVerdict — Multi-Agent Ad Review Pipeline

AdVerdict is a multi-agent ad-creative review pipeline that catches weak, risky, or non-compliant ads before a single dollar of ad spend goes out — built on Band as the agent collaboration layer. When a marketer submits a new ad creative and brief, a Coordinator agent opens a shared Band room and recruits four specialists. The Strategy agent scores brief, audience, and offer fit. The Copy agent scores and rewrites the hook, body, and CTA. The Compliance agent flags risky or unsubstantiated claims and missing disclaimers. The Performance agent predicts likely performance — hook strength, clarity, and fatigue risk. The standout moment is a genuine agent-to-agent loop that happens inside Band: the Compliance Reviewer flags a risky claim, the Copy agent rewrites it, and the Compliance Reviewer re-approves. Every agent posts real messages with @mention handoffs, and the room holds the shared context and task state. The Coordinator then assembles a transparent scorecard and returns a final verdict: GO (overall score at least 7, no high-severity compliance flag), REVISE (fixable issues), or KILL (critically weak or an unresolved violation). The verdict logic is fully auditable. Built as an all-TypeScript Next.js app using Band's Agent REST API, AdVerdict ships with a zero-setup MOCK mode for instant demos and a LIVE mode wired to real Band agents and an OpenAI-compatible LLM. It turns ad QA from a slow, subjective human bottleneck into a fast, explainable, multi-agent decision.
