Use ChatGPT or Claude to generate campaign copy by feeding it real inputs, not generic prompts.

Start with: “Write 5 Instagram ad captions for a fintech app targeting Nigerian freelancers, goal: free-trial sign-ups, tone: confident and simple.”

Take the best two captions, change only the hook line, and run them as an A/B test on the same audience.

This lets you validate messaging before spending heavily on ads.
