Sophisticated AI systems like OpenAI’s GPT-3 can write prose that’s impressively human-like, or at least good enough to fool the average person. They’ve been used to generate essays, poetry, stories, news reports and more to impressive effect. Perhaps it was only a matter of time, then, before entrepreneurs saw an opportunity to leverage such systems to write marketing copy.

Scale makes AI a great fit for ads. Copywriting is time-consuming work, and AI — being machine-powered — theoretically never stops working. But a greater benefit is personalization. AI systems can target the text of ads to particular segments of customers or even individual customers, making them resonate stronger. At least in theory.
