AI ad generation genuinely wins on speed for the tedious parts, character-limit compliance, breadth of messaging angles, negative keyword coverage, and second-language output. It reliably fails on facts it was not given, your actual differentiator, regulated industries, long-term brand voice consistency, and strategy. Every factual claim in generated copy must be verified by a human before launch. The productive pattern is AI drafts the assets while the human owns the strategy and the facts.
