Would you use an automated AI tool for your digital ads?

I'm a tech entrepreneur and I'm trying to validate (or rule out) a business idea I have: AI-based digital campaign manager.

My idea is this: Many small businesses can only spend several hundred bucks a month on online ads, and so it doesn't make sense for them to hire an agency to run their ads. But, on the other hand, they also don't have the technical know-how to do it themselves.

What I'd like to build is an AI tool (similiar to ChatGPT) that takes, as an input, an overview of the business, and automatically generates all the required assets: Which keywords/audiences to target, writes the ads, launches the campaigns, and even does the daily optimization and reporting.

Would you use such a tool?
