This tool is a content generator. It does not create reach. So I think I do not get your question? If you read the Pomelli article it states in the first sentences that Pomelli will help small businesses by creating campaigns. "Pomelli is an AI marketing tool designed to help SMBs more easily generate scalable, on-brand social media campaigns to help grow their businesses." But my point is, those campaigns are useless, if you do not have reach already. So, Pomelli does actually not help small business as they are stating, but instead is wasting your time and money, because you will end up in buying some ad words from Google.
Content is a component of reach.
Reach happens through channel marketing virally, virally typical happens via novelty.
Creative humans can use any tool to execute reach, this particular tool seems it would be a good one for that, in fact.
