ChatGPT + Codex for Marketing Teams (Full Guide)

ChatGPT and Codex are becoming something much bigger than AI assistants for enterprise marketing teams. Used correctly, they can operate as an intelligence and execution layer across the entire marketing organization.

Most teams still use ChatGPT one prompt at a time. This video shows what happens when you move beyond the chatbot.

We walk through how enterprise marketers can use ChatGPT and Codex across research, strategy, content, creative, analysis, operations, and execution, and how to build workflows that let your team get more done than ever before.

At Alephic, we build the custom AI systems that generic SaaS cannot: creative operations and review at campaign scale, brand intelligence for distributed teams, campaign planning across markets, content intelligence, and agentic workflows built around the way your organization actually works.

We work with brands including Amazon, Meta, EY, and Hilton.

Book a call with Alephic and we’ll show you how ChatGPT, Codex, and custom AI systems can transform the way your marketing organization works.
