Openai is now offering advertisers a feature that uses ai to re-write their ad to match the language, tone and style used by the target user in their conversation.
they're also rolling out 'sponsored agents' that activate when you click on an ad. ask it any question about the product and it's goal will be to answer and convert you.
its hard to see this not becoming the dominant way advertising happens online. incredibly personal, real-time ads that adopt to the way you're thinking and talking - built on millions of rich context in chatgpt.
